Sounds like your well on your way. A few tips that may help you along the way. Usually the bottom bolt hole in the thermostat housing is slotted so you don't have to fully remove it. Which should save you a headache trying to get it back in. Also be very careful with those bolts, spray some penetrating oil down there a few times before you go at it. If they break you'll find yourself in a world of misery. Good luck.

Need to see where the thermostat is located on 1994 chevrolet corsica

a simple way to find the thermostat on any vehicle, is to follow the upper radiator hose to the engine. Where the hose clamps to the engine has 2 maybe 3 bolts holding it on. Take out the bolts and the thermostat will be inside. be aware that coolant will leak out, and only do this when the engine is completely cool.

Replace themostst

Hello ,

The thermostat is located on the right side of the engine looking in,between the intake manifold and the air filter box, underneath the wiring. This is in a 1994 Ford Probe GT 6 cylinder.

To replace the thermostat, you really need to remove the intake manifold and this can be up to two or three hours work alone, even for a qualified mechanic.

It is in the housing at the engine end of the upper rad hose. When replacing it make sure the spring on the thermostat is toward the engine.

NOTE: Remove the air intake box so you can see below. There is a pipe running right into the bell housing where the thermostat is housed. There is one bolt that you need to remove (it is to the right,below the distributor) Then there are the other 12 mm bolts on the bell of the thermostat housing to remove. After removing those the thermostat should be able to come right out.

Thank you, hope this helps you out.

Need to see where thermostate is located have an idea but am not sure where it is the year is 1996 corsica 2.2liter v4

GM Corsica/Beretta 1988-1996 Repair Guide
The thermostat is located inside a housing on the back of the cylinder head. It is not necessary to remove the radiator hose from the thermostat housing when removing the thermostat.

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

Coolant leak at intake 1994 Buick LeSabre 3.8 ltr

There are several areas of possible leakage. One is the hose and plastic outlet from the intake manifold on the passenger side of the engine. The hose runs low, underneath the alternator. The plastic outlet cracks, the hose gets old, the clamps on the hose can also be loose. The replacement outlet from the dealer is steel, not plastic.
Another possibility for leakage is on the driver's side of the intake manifold. Underneath the air inlet is a metal cover on the end of the intake manifold. This covers the coolant passages at the end of the intake. Mine was oozing don't have to pull the intake to replace this.
The other place for leaks is the intake itself..requiring removal of the intake. I've done this...I don't think it is that bad of a job. However, if you put in a new intake, don't forget to put in a pcv fits under a small cover at the right rear of the intake manifold.
