Q: How Can I Improve Chevy Silverado 2500 W/Vortec 6000 Fuel Mileage?
We own several Chevy Silverado 2500 with Vortec 6000 gasoline engines. Model years range from 2002 to 2005. We used to get 15 to 17 MPG. Now we get 10 MPG. Any tips on how to improve fuel mileage and get it back into the mid-teens?
While it might be nice to extend the fuel mileage beyond the original, I am simply trying to get it back to where it was when the vehicles were new. We routinely use fuel injector cleaner. Sometimes this improves the mileage but the results usually only last for a few weeks. The results may be deceiving because we often use the cleaner right before a long trip.

These vehicles are usually driven an average of 30 miles per day. Normally these are highway miles with some city driving. Typically 2/3 highway, 1/3 city.
I believe that the intake filter has been changed but I will check it/them. Never thought of the exhaust issue. Sometimes these trucks are driven off road (construction) and it is possible that one or more of the guys hit something.

One of the vehicles (2005 Silverado 2500HD 3/4 TON) has a ladder rack on it. That one never gets good mileage. Usually 10 to 12 MPG. I suspect that the wind resistance of the ladder rack causes the poor mileage.

A: one of the best ways that i found to improve gas millage is a cold air intake. when gas goes into the combustion chamber not all of it gets burned up if you force colder air in as well the plugs fire and burn more of the gas that’s already in the chamber witch in turn improves your gas millage not by a hole lot but it does help. other things to check would be your plugs and wires and tire pressure

Q: What is the best muffler for my 2003 Chevy Silverado 2500?
Looking to get input on the best sounding muffler to put on my 2003 Chevy Silverado 2500HD (Gas) Ext. cab.
I would like something a bit more aggressive sounding than the stock system.
Thanks!

A: I am partial to Magnaflow my self. Nice deep rumble but not too loud. If your looking for a cat-back I would have to recommend MBRP. They make an exceptional product, priced about the same as the rest and the best customer service in the biz.

Q: I have a 2009 Chevy Silverado 2500 and want to install a factory remote starter from the dealer.?
I have heard alot of talk of remote starters being bad for your car/truck along with hearing stories of it having no effect at all. I am planning on keeping this truck long past the warranty but don’t want an electrical nightmare down the road. I work on a tight schedule and want the starter to let the engine warm up during cold winters. Does anyone have any advice/experience?

A: Dealer installed factory setups are not normally the problem, its the aftermarkets. Dealer installed parts do not void warranties.

or 2 way system
they are the same as the dealer option and you will save half of the price

Q: How much on average is insurance on a 2005 chevy silverado 2500 or ford F-250?
Looking to buy one of these vehicles and wanted to see how much on average it is. Thanks!

A: It varies a lot from state to state, even city to city. The two vehicles will be similar in price. It would be impossible to guess since we don’t know where you are. Just look in the yellow pages for a broker who deals with state farm, or something like that, to get started. Of course, show around with Geico and Progressive to get the best deal.

I’m more of a Ford guy, but with the F-250’s of that era, I would go with the Chevy. They tend to be more durable. Most of all, avoid the Ford diesel, if the one you’re looking at has one.

All the best.

Q: What would be the best mudding lift kit for a 1999 Chevy Silverado 2500 4×4?
Not sure about the size of the bed but I know there is a back seat and the door for it can only be opened if the front door is open. You may not have needed to know that but figured I say it anyway. So what is the best lift kit for mudding? Where could I get it and how much would it generally cost? And what tires would be best for it?

A: 4″ suspension lift.

Q: I was wondering I have a 2002 chevy silverado 2500 HD would changing my rear end help the gas mileage?
It is a 4:10 on a 4×4 club cab short bed 6.0 L I get about 12 mpg now.

A: You would have to change front and rear gearing equal, the highest you can probably change it would be around 3.55 I wouldn’t expect a big change in gas mileage maybe 2-4 mpg. it would take a long time to make up the expense with gas savings since you have to change the front ratio too.

Q: How do I turn off Daytime running lights on a 2004 Chevy Silverado 2500 truck?
I’ve tried pushing the interior light button 4 times quickly, I’ve tried turing the light switch dial back, but nothing seems to work. They are driving me nuts.

A: with a louisville slugger. LOL

Q: my 2001 chevy silverado 2500 will not engage the 4 wheel drive. does anyone think it is the actuator?
4 wheel drive would engage periodically , but will not engage any more.

A: First things first: check your 4WD/ATC fuse in the underhood fuse box. Both of these fuses should be good and have power. Also, when you push the 4wd engage switch, does the indicator come on? If not, might have a bad switch. If so, could be a the encoder motor (actuator) or the transfer case shift controld module. Take your truck to a local Autozone or Oreillys and have them scan the vehicle for free. Usually, if its a fault in the computer of circuitry, it will display a code. And if it doesnt, it might be a mechanical malfunction. Good luck with it.

Q: I have a 2001 Chevy silverado 2500 extended cab and i wanted to put some subs under the back seat?
Does anyone know how much a special box cost so the subs will fit under the back seat thanks…

A: Go to www.jlaudio.com and look at their stealthboxes. They incorporate a sub or subs and space for an amp…all fitting into the smallest nooks and crannies of most vehicles while providing the best sound. Some even replace your seat console! They’re pretty awesome. I’d say you’re looking at around $300-500 for JUST a box whether you buy a Stealthbox or have a good car audio shop custom build you one. However, I’d HIGHLY recommend a stealthbox even over a cusom made one because the stealthboxes are engineered for optimum sub performance in a small space…not just “fitting” subs into a small space like the local stereo shop will do.

Q: 1989 chevy silverado 2500 need to change valve seals?
what are the step i need to do so i can change the valve seals my truck has been smoky.,,, any websites i want todo it myself… 1989 chevy silverado 2500 350 engine 5.7L

A: First find out if that is the issue.

Do a wet/dry compression on all the cylinders.

That is where you do a compression test on all the cylinders and write them down.

Then squirt about three pumps of oil from a oil can into each cylinder and retake the compressions.

If the compressions don’t change and are low, the valves are burnt and you need a valve job. If the compressions go way up after the oil seals the rings, then the piston rings are bad and the engine needs rebuilding and that may be where the oil smoke is coming from.

If all the cylinders are within 20 psi and runs good, then it may be your valve guide seals are bad. You can replace them without pulling the heads.

You can go to an auto parts store and buy a valve spring compressor that is used while the head is on the block. It has an air fitting that screws down into the spark plug hole and when filled with compressed air, holds the valves up while you remove the spring and replace the valve guide seal.

Q: how do you remove the front differential drive shaft seal on 1990 Chevy Silverado 2500?
Trying to replace the front differential drive shaft seal and the seal that goes to the drive shaft on the transfer case. The truck is diesel and is 4×4.

A: Take a cold chisel and a hammer and beat on the edge of the seal enough to warp it enough to remove it. Use a seal installation tool to put the new one in. Auto Zone or NAPA will probably lend you a tool to put a new one in.

Q: How do you remove a spindle nut fro a 1998 Chevy Silverado 2500?
What size socket do I use?

A: If its 4×4 is a big one. I dont remember what size it is but its one that comes in the standard sets you can buy. Sometimes you need the ones made for axle nuts with the thinner side wall to fit in the recess. Standard sockets that big tend to have fairly thick sidewalls and sometimes dont fit.

Q: Does the Chevy Silverado 1500 extended cab have a different wheelbase than the Chevy silverado 2500 crew cab?

A: I think it might because a Crew Cab is longer than an Extended Cab. But you can never be to sure…
