Tip & How-To about Chevrolet Venture

Chevy venture thermostat replacement

If you find yourself in the position of changing out what looks to be an impossible thermostat on the 3.4 engines in the venture, you might not be as bad off as you thought! first you must remove the air box lid and hose from it so throttle body. next you must unhook the throttle linkage bracket from the intake, two black bolts on top. Now the fun starts, the throttle body bolts to the intake with two bolts, one it right on top in front, the next is opposite the first on the bottom back and also holds a coolant line mount tab. You will remove a nut to allow the mount tab to come off (carefully pull it out, it will come off and give enough to get out of the way but it will fight the entire time), now you will need a deep well socket to go over the stud to the actual bolt that holds the intake on. once you have the intake loose you can swing it out of the way gntly to reveal the tightly packed thermostat housing nestled in beside the exauhst!! Here is a little tip to help, the front bolt, as before, is easy to remove, the lower is about 3/4 of an inch from the exauhst and will take a wrench, which you will have almost no room to swing. BUT... this bolt DOES NOT need to be removed, only losened, AND... I have found that by trying a few different wrenches (different brands of the same size) you can get a little extra here and there, and if you reach around and slide the wrench in from the back of the motor, you can take your swing a little farther (alternate from front of motor to back of motor)! and there you have it, you will loose antifreeze, replace the thermostat, and repeat the steps above in reverse order, refill you antifreeze, including the over flow up to the full cold line, and let it run, there is a brass bleeder screw on the housing that im sure you will bump atleast once in this process, use it to bleed off the air out of the system by turning the top portion only counter clockwise until you hear a hiss or see coolant, once the coolant comes out consistant your good!! top off the coolant and pat yourself on the back!!

Most thermostats come with a gasket, the gasket for the throttle body (if you cant reuse the old on) is FEL-PRO # 60983.

need diagram of where thermostat is located on 2002 chevy venture


If you follow the upper hose to the metal housing on the drivers side of the engine the thermostat is behind that housing.

A 13mm socket, some extensions, ratchet, 13mm wrench and a lot of patients will be needed. Its not impossible to do but as you get into it you will think so!

where is thermostat


Hi this is a big job and not the kind of job a novice can do below is the instructions on removing and refitting the thermostat

    Remove the Thermostat
  1. 1 Place a catch pan under the drain valve of your Venture radiator.
  2. 2 Open the radiator valve and drain at least 2 quarts of coolant. Then close the drain valve.
  3. 3 Remove the air cleaner and duct assembly from the top of the engine to gain access to the thermostat housing. Use a screwdriver and a ratchet and socket if necessary.
  4. 4 Disconnect the crossover exhaust pipe using a ratchet, ratchet extension and socket.
  5. 5 Follow the upper radiator hose towards the engine to locate the thermostat housing.
  6. 6 Disconnect the upper radiator hose from the thermostat housing. Use a pair of rib joint pliers to loosen the clamp, and then slip it off the thermostat housing towards the radiator. Other Venture models may use a worm clamp type, which you can remove using a standard screwdriver or ratchet and socket.
  7. 7 Remove the upper radiator hose from the thermostat housing by carefully twisting and pulling the hose off the fitting.
  8. 8 Unscrew the two mounting bolts from the thermostat housing using a ratchet, ratchet extension and socket. Detach the thermostat housing from the engine.
  9. 9 Note the exact position of the thermostat so that you install the new one the same way. Then remove the thermostat and gasket.
  10. Install the New Thermostat
  11. 1 Apply a light coat of room temperature vulcanizing (RTV) sealer to the threads of the thermostat housing bolts.
  12. 2 Set the new thermostat and new gasket in place.
  13. 3 Set the thermostat housing in place and start the two mounting bolts by hand. Then tighten the bolts using the ratchet, ratchet extension and socket.
  14. 4 Connect the upper radiator hose to the thermostat housing.
  15. 5 Tighten the upper radiator clamp over the thermostat housing using the rib joint pliers, standard screwdriver or ratchet and socket.
  16. 6 Connect the crossover exhaust pipe using the ratchet, ratchet extension and socket.
  17. 7 Install the air cleaner and duct assembly using the screwdriver or ratchet and socket.
  18. 8 Add coolant to the radiator using a 50/50 mixture of distilled water and anti-freeze.
  19. 9 Start the engine and check the upper radiator hose and thermostat housing for leaks.

if your doing the job yourself then just take your time and remember where all the bolts you undo come from as putting them back in correct order can be a nightmare.

plz rate this solution as unrated posts will be removed from the site, plus i have a whole page of unrated posts, thanks
