The top radiator hose is connected to the thermostat housing on the engine, the thermostat is inside that housing, which only has 2 bolts.

Simple solution is to get the repair manual from the parts store ($25 but well worth it) Short of that the thermostat housing is always at the end of one of the radiator hoses and has a minimum of 2 bolts bolting it to the block. Sorry I don't have an exploded engine view to send you. if you can find the bolts and housing at the end of one of the hoses then the manual would be the course of action I could recommend.

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.

How to get to the thermostat on a ford aerostar 93 awd van?? where is it located??


1993 Ford Aerostar 4WD 4.0L MFI 6 Cyl Repair Guide

1. Drain the cooling system with the engine cold.

CAUTION When draining 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.

2. Remove the retaining bolts for the thermostat housing. Lift the housing clear and remove the thermostat. It may be easier to clean the gasket mating surfaces with the heater and radiator hoses removed from the thermostat housing.
