Why does my '93 chevy suburban over heat while idle


I would check the clutch fan or (radiator fan), try this when the truck is cold the fan should spin free and when it is warm the fan should stiffen up. the fan should spin slower when cold and faster when warm.

Where is the valve idle air control on 1996 chevy suburban


if you follow the air cleaner/filter tube to where it meets the motor you will find the throttle body and it is mounted in the throttle body on the opposite side of where the gas pedal cable mounts. it has a 4 wire plug i believe.

Vaccum hose diagram for 88 chevy truck. I put a 350 motor in my 88 chevy 1500 truck from a 95 suburban. I cant get the throttle body to stop idaling to high. I may need a vaccum line diagram for this motor...


it may not be a vacumn leak from a line,check the throttle shaft for movement,for example,i had a 89 1 ton 350 and my throttle shaft was moving around a lot and in order to keep it from idling high,i had to kick the throttle pedal.But also check the idle air control valve,which is the round sensor on the side of the throttle body.

1999 chevy 350 runs rough at idle. #4cyl misfire. light gray build up on spark plug. compression good 180.


You either have a bad spark plug wire or coil pack. The light gray color on plug is normal.

I have a 2001 chevy suburban and it is idoling way too high. Once I put it in drive it goes back down. Sometimes when I am driving, it does not want to shift either.


sounds like you have 2 different issues on this one. the high idle concern..i have repaired many of these with the same concern. check for vacuum leaks first, if all is ok, then check the idle air control (iac) on the side of the throttle body. replacing the iac motor 99.9 percent always fixes this concern

I have a 93 Chevy Suburban 1500 and the Transmission won't shift into any gear. I have an 1983 Chevy Suburban Transmission that is still good. Can I use the 83 Transmission in my 93 Suburban?


Not without a little adapting. The 1993 has a 4l60e which is electronically controlled and has shift solenoids. If the 83 is an overdrive it is a 700r4 which is the same trans but not electronic. If you put it in the speedo wont work and you will need to install a T.V. cable so the transmission will shift. The 93 won't go forward or backwards?

All Suburban vehicles are equipped with only one of these choices. Good luck.
