Tip & How-To about Chevrolet Venture
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.
