Follow the top radiator hose to the engine. The top radiator hose is clamped to the thermostat housing. Two bolts fasten the housing to the engine. On V8's it bolts to the intake manifold.
front of the engine where the neg cable is grounded next to the cable you will see a dome like housing two bolts the thermostat is in there. be careful when tightening the housing if the thermostat is not seated properly you could brake the housing also if you tighten it to much you could brake the housing.
A thermostat always looks like a small rubber valve with a spring. It is inside the thermostat housing on the top of the engine (top coolant hose exit)
The thermostat on a 1984 ranger is located in the lower radiator hose housing connected to the engine, not the top like most vehicles..Fairly easy to replace. Just remove the bolts.. then the housing and the thermostat.
The thermostat on a 1998 Grand Prix can be located by following the radiator hose (at top on the driver side) to the engine. The housing that the hose is clamped to has the thermostat in it. Just remove the housing (two bolts) and you will see the thermostat. Its a tight spot but if you remove the air filter and remove it from the throttle also, then you can access the thermostat housing. Removing the bolts from the thermostat housing can only be done in small increments(short turns). I think its a 10mm wrench or 13mm can't remember but its metric somewhere in that range and only a wrench will work. Its impossible to get a socket wrench in there. Have patience and keep turning. CAUTION CAUTION! (Also make note to how the thermostat sits in the housing, because if you sit the thermostat in the housing wrong you will not be able to put the housing back in position. It will be confusing if the thermostat is in wrong. It just won't fit back in place like that.)
if it is a 3ltr diesel follow the top hose to the engine and that the housing for the thermostate
it should be by your thermostat housing
depending on the year of the car, Chevrolet had developed cars that had the same body style, but with different names. for example, in 1968 Chevrolet had built the chevelle.and this body style had several different variants, one would be a Malibu, then a chevelle Malibu, a chevelle, and a chevelle super sport. so a chevelle clone would be just taking a car with one body style, and converting it to a different variant that had the same body stylr. it would be like taking a chevelle-Malibu abd converting it to a chevelle ss.
take off the water pump housing on the front of the engine, ancilleries like the air pump may need to be removed also, the thermostat is located directly behine the pump housing, wil pry out once the housing and water pump are off.
Not stock. Maybe if you went thru COPO or somthing like that. 1964 absolutely did! http://www.ss396.com/1964/Chevelle/parts/1964_Chevelle.htm The 327 was available stock in various horsepower options from 1964 thru 1968.
Any GM engine only has 1 thermostat. On the 4 cyl, many people get confused as to its location. It is not in the upper radiator hose / housing on the engine. This looks like it should be ther, but it is not. It is actually on the back of the motor, under the exhaust manifold. Have had some people put a thermostat in the housing on the top that looks like it should have a thermostat. This caused overheating problems. TechJK ----------------------------------------------
sounds like either the thermostat housing or hose connection.
On a 1994 Ford Explorer , 4.0 liter EFI , V6 engine : Follow the top radiator hose from the radiator If it is like my 1995 the radiator hose connects to a metal pipe which is part of the engine coolant thermostat housing . The housing is bolted to the front of the engine and the engine cooling thermostat is inside the housing
