Re: Exhaust brakes & super chips
|
I am the guy that was wondering if I needed to spring for a Diesel or not because of mileage. I don't have to switch trucks often to stay happy, and I am going to be putting a lot of miles on this truck. I got a guy at a used dealership who has a '94 1/2 ton Z71 Ext. Cab Diesel that has 110,000 miles on it. He's asking $9,500 and I am just wondering what sort of deal this would be for me. I am not going to be pulling anything with this truck... except for the odd trailer here and there and possibly a RV trailer one of these days in the next couple of years if I can get one. I haven't seen many 1/2 ton diesels and someone told me that's because they had front-end problems because of the weight of the motor??? Is this so? Thanks for the info and advice... love the site!
Hi thanks for visiting my website. I'm not found of the older GM diesels. Yes even the older GM diesels are heavier than a gas engine and will give you some expensive problems, suspension and engine. For fuel mileage, a GM Vortec gas 4.3L V-6 in the same truck your looking at will be close behind the GM diesel in fuel mileage and last a heck of a lot longer. Good Truck'n. MT
I've recently purchased a 2002 F250 Crew cab 2WD 7.3 Diesel. I'm going to be pulling a ~6000 pound RV trailer (bumper pulled). My question is: Is it safe to pull the trailer with the overdrive "On" and using cruise control? I have heard that in hill/mountain areas, I should definitely not use the overdrive. What is your opinion on semi-flat highway towing with this type of truck and trailer? Your comments would be much appreciated.
Hi, with just a 6000# trailer, your F250 should pull that with overdrive and cruise on. I would shut the overdrive off coming down the mountain to give you some engine braking. The 2002 Ford Super Duty series has a new tranny temp gauge in the dash on the upper right side. When you are pulling in the mountains in overdrive watch that gauges and see where it goes. It shouldn't move a lot. If you pull a trailer of say 10,000#'s or more in the mountains I would shut off the overdrive. Good Truck'n. MT
my father in-law bought a 36 ft. fifth wheel now has looking for a truck whets better ? I am Chevy his brother is ford and he has to have gas. does the vortec 8.1 have a edge on the ford v-10? how about trans. and gearing i say 4:10 also would dual wheels on the back axle help or not? and last braking and does anybody offer headers and other upgrades including exhaust brakes?
Hi, thanks for visiting. If you’ve read my site you know how I feel about new engines their first year. I know this is the second year for the GM 8.1L V-8, but they hardly sold any in 2001. I think it's a gas mileage thing. You might be able to find a new 2001 out there somewhere. You can get the 8.1 in a dually with the 4.10 rear axle and with the Allison 1000 automatic. It has more torque and horsepower than the Ford 6.8L V-10. The Ford V-10 has been out since 97. Actually 70% of the class A motor homes (the big ones,) that have gas engines, use the Ford Triton 6.8L V-10. It will be interesting to see have many motor home manufactures switch to the GM 8.1L. I wish GM would loan me an 8.1L with an Allison 1000 to test for a year. There just aren’t enough out there in use for me to have enough data to give you more advice. As far as duallies, I like duals for the stability, bigger brakes, and they look cool. I’ve sold duallies to people who didn’t need a dually but wanted to put the company signs on the side and the dually gets noticed more. I like Banks exhaust brakes, but there are several good ones out there. Exhaust brakes can mess with warranty, so check it out. I hear the argument both ways on that and it comes down to lawyers. Good Truck’n. Oh by the way, my new disclaimer: I like lawyers. MT
I am in the process of ordering a 2500HD Duramax diesel. This truck will be used for my everyday driving as well as towing. I need to know who has had trouble and what the problems have been? Is the tranny ok or too much for the truck? If there are good things let me know that too. Yes I read your article and I hope the 2002 are improved. Let me know-thanks
Hi, thanks for reading my web site. I was actually surprised by the problems of the Duramax. And most of the problems were from people pulling workloads. I’ve also heard good things from people pulling smaller RV fifth wheels. I expected head and head gasket problems with the aluminum head. But Duramax owners have told me about, broken crankshafts, blown head gaskets, broken front shocks, broken front stabilizer links, replacing front ball joints, starting problems, entire fuel systems replaced, etc. For some Duramax owners, the tow truck has become an accessory. I like the technology behind the Duramax and Allison 1000. GM has some great ideas in this new combination. As soon as dependability catches up with the technology, I’ll stop bitching about them. These are my opinions from my research, reviews and interviews; the softer stuff comes from magazines that get the big advertising from manufactures. I would love to hear more good stories from anyone out there about their Duramax or Allison 1000. Anyone out there have a 8.1L V-8 gas engine with the Allison 1000? The nice thing about any of the new diesels is the 5-year or 100,000 warranty. If you have the time, it shouldn’t cost anything to fix the Duramax for a while. Gosh, time for another cup of coffee. Please let me know how your new Duramax works for you. You should get a good price on an ordered truck; it doesn’t cost the dealer interest or floor plan. It should be like $1000 over invoice. Good Truck’n. MT
I recently bought a used 96 dodge with the Cummings diesel and I have loved the truck since I bought it! But i have had some problems with the tranny lately? Q: It seems like the clutch is slipping and the motor reves but I don't seem to move until the clutch seems to grab again. i went to adjust the clutch but found that it is all in closed and you can't adjust it. can some one give me a hint on what to do or if they might know what is wrong with it?
Hi, with hydraulic clutches that the newer trucks have and all diesel pickups have them, you don't have adjustable free play anymore. This makes it hard to know how much wear is left on the clutch discs. You could have the master slave valve out. Or it's possible you have a oil leak somewhere, which is soaking the disc plates. Do you see any leaking around the tranny? If the rear main seal on the engine was leaking or the clutch slave valve, it could cause slipping. Sounds like surgery. Let me know what you find. Good Fix'n. MT
One stop truck shopping, comparing, buying, and selling, new or used. I highly recommend this great service.
I am looking for a truck that will get decent gas mileage, over 20 highway. But be able to pull a 2-horse trailer (6,000# max). I am looking at the 2001 Dodge Dakota quad cab. Will this get the job done or would I need to go full-size? I put quite a few miles on for work and would like to get the best gas mileage I can but still be able to pull the trailer. Any help would be appreciated.
Hi, the Dakota with the 5.9.L V-8 the 5.2L V-8 or the new 4.7L V-8 will pull the trailer. With the 5.2L V-8 you could get 20 mpg with a 2-wheel drive on the hi-way when you're not pulling a trailer. The issues I have with the Dakota besides how badly they rate with Consumer Reports, is they cost so close to a full size pickup. For gas mileage the Chevy, GMC, 1500 with the 4.3L V-6 Vortec is the best I've seen in a full size gas engine. But under a load like 6000#'s the 4.3L V-6 tends to overheat... I just looked at the EPA's gas mileage booklet for 2002 and the GM 4.3L V-6 still shows the best mileage in a 1/2 ton. So if you can afford it get the new Chevy or GMC 1500 with the 4.3L V-6 automatic, ( you have to go auto tranny to get the best tow capacity until you get to the 3/4 tons.) Get the heavy-duty auxiliary auto tranny cooling, heavy-duty trailer tow equipment and a 3.73 rear end. Today I'm adding a link to the EPA gas mileage ratings. Go to home or my front page and look on the left gray column next to the "Rebates, Recalls and Rates." Let me know what you decide and you experience so we all can learn. Anybody else have opinions on the right truck for pulling and gas mileage? Good Truck'n. MT
Hi, again if you are pulling your trailer in the mountains, the V-6 won't cut it, you will have to go up to a larger V-8. The Chevy or GMC with the 4.3L V-6 Vortec auto and 3.73 rear axle ratio has a 10,000 # combined gross vehicle weight. If you get a Chevy or GMC crew cab to give you the room of the Dakota Quad cab you may be over the 10,000#'s. So part of this equation envolves which cab configuration you need. I know I'm as clear as mud but I do want to see you get the right truck. Good Truck'n. MT
I am looking to by a truck that I plan on putting a LOT of highway miles on. I work about 50 miles from home and drive that distance at least twice a day, not to mention we like to go out and have to drive back to town for that. I am the type person that will keep a vehicle as long as it will run, I don't need something new every couple of years, so I figured a diesel would be a good candidate. I here these 250,000 miles plus stories all the time. Should I spend the extra now on a diesel? Will the gas mileage save me that much? Thanks.
Hi, a rule of thumb of 80,000 miles depending on the price of fuel to pay for the diesel engine from fuel savings over a gas engine. Today generally a large enough gas engine geared low enough to pull near a diesel is (Ford 6.8L V-10 4.30 rear axle, Dodge 8.0L V-10 4.10 rear axle, GM 8.1L V-8 4.10,) will get roughly 50% to 60% the fuel mileage of a diesel. Sometimes they are a little closer but not much if you gear the gas engine low enough to pull a large load like the diesel. There is a reason that you don’t see over-the-road semi tractor-trailer rigs with gas engines. So if you trade often and don’t pull a heavy trailer much, the gas will work. If you pull a lot, keep your truck a long time or just love the power, the diesel is the choice. Service the diesel on schedule and you should expect to join the 300,000-mile club. If you like to shift your diesel and economy is more important than convenience, the manual tranny can get a couple more miles to the gallon than the auto. Good Truck’n. MT
I need to get a new (used) truck the old 78' Chevy is worn out. I have narrowed my decision down to two Models, the Ford F250, Diesel, 6speed 4x4, or the Dodge Ram 2500, Diesel 5speed, 4x4. I would prefer the Dodge because I have heard so many good things about the Cummins. Although it seems that the Dodge is very hard to come by used. I would rather not pay for a brand new one. Any suggestions. I would appreciate some advise. Carlos Elk Grove, CA
Hi, thanks for visiting my site. I put about 300,000 miles on my 77 Chevy and learned to be a mechanic keeping it running the last 200,000 miles. You are going to like having both fuel tanks on one side! Ford diesels out sell the Dodge diesel 3 to 1 which is why it's harder to find used Dodges. The short answer, because I'm ill and can't see the screen very well, is if you are buying a 99 or newer get the Ford, if 98 and older get the Dodge. Ford didn't make a 98 but came out with 99 early. Good Truck'n. MT
Would you comment on ride quality (empty load) on a 250 vs. 350 ford truck. Mainly city and highway roads- a few potholes. Both would have a non factory camper upgrade suspension. If I rarely (if ever) need the extra hauling capacity should I buy the 250 vs. the 350? Thank You!
Hi, This question gets me in trouble with Ford. The F350 cost another $1000 and the only difference I've found is the 2.5" spacer on top of the rear axle, to raise the back up, and Ford gives the axle on a F350 around a 800# higher rating than on a F250. In 99 the F250 was jacked up also. Ford then discovered that not everyone’s trailer or camper would fit the new tall truck; so one time under warranty Ford would lower the truck for you. From 97 and back the F250 and F350 had different axles and springs. Then Ford came out with the new model, Super Duty replacing the Heavy Duty in a 99 model. The F250 and F350 share everything. But then there is that “magic spring dust.” Somehow without making the trucks different Ford gives you a 9900# gross vehicle weight on the F350 and 8800# on the F250, but the trailer capacity is the same. That kind of gives it away magic spring dust and all. So I usually recommend saving your money and get the F250. Manufactures are always trying to do one better than the competition, so why not more configurations to brag about. Back to your question. The F350 does ride a little rougher than the F250. Try them yourself and let me know if you can tell the difference. Good Truck’n. MT
Thanks for a previous post answer! This site is an example of what is right with the internet. Are there different types of diesel fuel? If I pull in to a gas station is there one type best for my truck? Sorry for my basic questions but I wish to learn. Pat
Hi, Thanks for visiting my site. Normally diesels run on #2 diesel. #2 has lubricating qualities that make it oily, smelly and stays on your hands for a few days. #1 diesel is like kerosene or jet fuel and less oily. The lubricating properties in #2 are what gels when extremely cold. Most service stations in colder climates blend #2 and #1 50/50 in the winter to keep your fuel from gelling. You don’t want to experience your fuel turning into jello. It’s not fun using a hair dryer on your pump and fuel lines. But if you go to a warm state, (California, Arizona, Florida, etc,) in the winter and buy fuel there, you may want to use a diesel additive. If you are out of your area, buy your diesel at a truck stop. They should know what you need to drive home with. Good Truck’n. MT
