How do you replace the thermostat on a 2001 Chevy Venture?
everyone should have a manual for their vehicle, and the library should have a professional shop manual available in the reference section for FREE to make copies of...read up and fix like a pro!! ) Dave
Dave, if we had a manual at home, we wouldn't be asking for help...now would we?
The thermostat is beneath the throttle body & behind the exhaust crossover pipe.
It's a ridiculously big job considering it's only a thermostat you're trying to replace:
1) Remove the air cleaner & duct assembly.
2) Drain coolant (rad drain plug on bottom corner, driver's side) below thermostat level.
3) Remove the thermostat bypass pipe. This pipe starts on top of water pump (front- passenger corner of engine) and goes along front cylinder bank, turning towards back across the driver's side of engine. there are about three bolts & three pipe clamps to remove.
4) Remove the exhaust crossover pipe heat shield bolts. There are two bolts in front & two in back. Remove exhaust crossover pipe heat shield. (These bolts may be frozen & decomposed because of heavy oxidation due to high heat, good luck)
5) Remove the exhaust crossover pipe; 3 bolts at each end.
6) Remove radiator hose from thermostat housing, remove thermostat housing & get that sucker.
7) Clean everything & reassemble.
NOTE: when filling cooling system, don't forget to let the air out using the (2) bleeders; near water pump & thermostat housing.
Edit Note for #3 #4 and #5 number 3, top of water pump pipe is held on by one bolt. take that off, on the throttle body, their is a nut holding it on, you must take the throttle body off, so this comes off anyways, this allows Evan leway to move it out of the way. as for 4 and 5, you don't need to remove the cross over pipe or anything else if ur using a wrench. worked for me keeping it in
Can you get a detailed picture of where the Thermostat is on a 2001 Chevy Venture and instrustions on how to change it?
I have had a problem with mine. I have a 1997 Venture. I was told that it is very hard to get to and can take a mechanic around two hours to take out. Unfortunately, my thermostat has a bolt that is stuck and will not budge. The mechanic would have to go about getting it out another way. There was a 50/50 chance that it would come out without ruining a part that would…

You replaced the thermostat in your 2001 Chevy venture but the van is still overheating the top radiator hose is hard and hot to the touch like the thermostat is not opening up please advise?
Follow your top radiator hose into the intake manifold. The radiator hose connects directly into the thermostat housing. Take the bolt out of the left (drivers side)side of the housing and then take the nut off from the right (passenger side)side of the housing this will expose your thermostat. Be sure to replace the gasket when you replace the thermostat.
Are there any sensors or relays on a 2001 Chevy Venture working in conjunction with the thermostat which control the radiator fans and if so where are they located?
Its located under the throttle body or follow the upper radiator hose til it hits a semi round housing. There is 2 bolts to remove it. First you have to drain the radiator fluid of course. I am changing the thermostat right now on my 2001 Chevy lumina and I see I will have to also remove the throttle body to get to the thermostat housing
