93 Olds Ciera 3.3L + tips on changing thermostat
I would like to change thermostat….believe it is stuck open.

Found the housing tucked under the Throttle Body. Exhaust pipe under air filter housing make things tight.

My inclination is to remove Throttle body for easier access to thermostat housing.

My first time performing this job on this vehicle. Otherwise competent.

Suggestions, tips, or previous threads on this ?

Thanks.

LudlowLou

Removing the throttle body won't help.
You may have to use a 1/4 swivel socket and bend like Gumby but I've done many that way.

I believe the bottom bolt is slotted so it doesn't have to be removed all the way.


Here are the instructions

1. Disconnect battery negative cable.
2. If necessary, remove air cleaner assembly.
3. With engine cool, drain engine coolant below thermostat level. Never open cooling system with engine hot.
4. Disconnect radiator hose from thermostat housing.
5. Remove thermostat housing retaining bolts, then the housing, gasket and thermostat.
6. Reverse procedure to install noting the following:
a. Ensure thermostat gasket area is thoroughly clean.
b. Install thermostat with new gasket.
c. Apply a suitable sealer to thermostat housing retaining bolts. Install and torque bolts to 20 ft. lbs.
d. Refill and bleed cooling system as necessary.


Note, if this uses a rubber O ring, don't use any sealer.

Those are the exact same instructions I gave you minus the picture.

I had to delete your link. They are not allowed here.
