Replying to: redgms (Jan 20, 2008 9:28 am) I have a 2000 4.3 and my thermostat is in the cap of the radiator (top of radiator, passenger side).

Replying to: redgms (Jan 20, 2008 9:28 am) Follow the upper radiator hose back to the top of the engine. The hose attaches to the thermostat housing. Chevy thermostat housings are usually held on with two bolts. Be careful when reinstalling and check that the thermostat is fully seated, the gasket aligned, and the housing is sitting flush before tightening the housing. Many a housing has been replaced because it was tightened down on the lip of the thermostat and cracked.

Replying to: leoandme (Dec 10, 2007 10:20 pm) I'm having a similar problem with my 2000 ZR2. The courtesy light fuse keeps blowing and I then noticed my 4x4 switch light was out too. When I put a new 10A fuse in for my lights (which blew the next day) my 4x4 switch lit up. My question for you is when you were having your trouble, was your 4 wheel drive still able to engage? Mine will not engage while this particular fuse is blown, and the switch light is out. Any help would be much appreciated. Thanks

my girl freind was driveing my 95 Blazer w/4.3 and it died. she thought it was out of gas. she put 6.5 gals in it and it still did not start. I checked for spark and it is good. i cant hear the feul pump like i used to hear it when i turn on the ign. i found 2 relays in the glove box and i assumed tat one of them was for the f/pump. i swaped them and no difference. should i buy a pump and install it or do i need to do more testing. i had a simular problem with a 85 century but it turned out to be in the wiring an i riged it up with a wire direct from the fuse box but i dont want to rig this one. i know that is a common problem with the 80's gm's...t/u for advice in advance Replies to this message: toleson (Jan 22, 2008 9:28 pm) pepperjensen (Jan 22, 2008 9:36 pm) 00jimmy (Jan 23, 2008 9:38 am)

Replying to: pepperjensen (Jan 22, 2008 9:36 pm) It is likely that the pump is dead. However, you may be able to access the electrical plugs on top of the tank if the spare is out of the way. Make sure the connections are good before dropping the tank. I found using a motorcycle jack is a nice way to support and lower the tank.
#3124 of 3449 Ball Joint, Idler & Pitman Arm Repair Problems by csf2 Jan 25, 2008 (11:38 am)
4x4 02 Chevy Blazer had service engine lite on 69k miles. Chevy repair shop replaced upper/low ball joints, idler pitman arms. Said thermostat stuck open, waterpump leaking all repaired. Blazer now rocks side to side (like wave motion)whenever it hits a bump or road irregularity (ie always). Took back to repairshop-they said drives normal and w/in specs. Possible cause? Any help appreciated and thanks.
