#869 of 877 gas mileage
Feb 13, 2004 (11:03 pm)
I own a 2003 1500HD with the 6.0L and the 3.73 rearend with quadrasteer. What type of mileage should I expect? I currently get 8-9 in town and 11-12 on hwy. Is there a computer chip or something that will improve the mileage. I'm somewhat disapointed in this result after you hear of tahoes etc. getting 17-19 mpg. on hwy.
Thanks for any responses.

yes you still need a brake controler. GM has a nice adapter plug (posibly came with the vehicle, available at the dealer) makes installation very easy.
step 1: attach 4 wires from adapter plug to 4 wires on brake controller
step 2: plug adapter into wiring harnes to the left of the brake pedal.
no drilling, no wires to run all over the truck

We are wanting to purchase a 2004 Silverado
extended-cab, two-wheel drive truck. The vehicle
we drove had excessive noise at speeds 60-64.
At 70-73 the vehicle was perfectly quiet.
I drove four additonal vehicles similar to the first one I drove. All of them had the same
My hod-roding days are over so I do not want the
extra noise. Have any of you experienced this
problem with your Silverados? I read the message
board posts for a ways back and did not see any
reference to this problem.
Thanks for information.
#872 of 877 Winter Gas...

I think it's the same all over for the colder climate states. Only difference in N.Y. now is they banned MTBE which was used to oxygenate the gas and instead use 10% ethenol. MTBE is polluting all the drinking water wells from the underground tanks leaking an causing havoc with homeowners effected. MTBE causes cancer and mixes easily with water. I sure wouldn't want a cup of it. Of course the gas manf's are getting a $2 billion bail out from the government to help ease costs of the transistion from MTBE to ethenol. Talk about fleecing the taxpayers, has anyone see the price of gas DROP lately ??NOT!

ours have, but will undoubtedly go right back up. they keep bouncing back and forth between upper 1.40's and mid 1.50's for 87 octane. (Austin, TX)

If you're curious, we have a topic over on the News & Views board where folks report their local gas prices. Interesting to see the variations across the country. Here's the link:

New to this forum -- looking for info about a cooling leak on my 97 vortec 5.7. Leak is around the head gaskets. My mechanic said the problem was common to the vortec engine. This true? He thought GM was aware of the problem and had considered a recall to fix. Any comments or where to look appreciated.
#877 of 877 Sierravista. coolant leak..
Feb 19, 2004 (6:52 am)
The leak you mention is pretty well known. The leak is usually from where the intake manifold and the head meet. The coolant passage is leaking. On the 97 vortec motors, they use a low torque intake gasket. It is somekind of ceramic polycarbonate with rubber inlaid around all of the passages. The ceramic fails over time and thus your leak.
Rumors are that some of the factory installers torqued the intake manifold too tight.
The intake on this motor is torqued in inch lbs versus the normal ft lbs.
