Thermostat is going how do i replace 6cyl. - 1997 Chevrolet S-10 Pickup

might be simple radiator cap need replace,or a blockage in waterways try flushing them ,if not get it pressure tested .

The top picture is thermostat housing. It appears to be toward front of engine, lower, driver side. Usually, one of the radiator hoses goes to thermostat housing.

The thermostat housing is to the right side of the engine, mounted under the coil pack location. Look for the coolant hoses going into the housing with the 3 temp sensor harnesses in the front of it. That whole assembly is the thermostat housing. The thermostat itself is inside of it.

If you plan to do this yourself, I suggest removing the battery (for better access) and drain the coolant before you pull the thermostat housing off. Be aware that the housing is plastic and it will need replacing if it is cracked or damaged during removal.

The thermostat is located in the thermostat housing, which is mounted to the coolant crossover tube. The bypass hose is connected to the thermostat water inlet on one end, and to the intake manifold water outlet on the other. The thermostat is not located in the intake manifold water outlet, where the upper radiator hose is connected.

is there any air in you system i know from experince this cars can be stuburn and it also seems like a head gasket

On the 3.8 6cyl it's near the thermostat housing, it looks like a spark plug that has 2 wires going to it.

3.3 6cyl may be similiarly located near the thermostat housing.

Autozone.com has troublshooting section and repair section online that may show the exact location

Hope this helps.

have you recently replaced your waterpump ?

thermostat is located at the end of the lower radiator hose, not the upper like most vehicles. Remove the two bolts (most likely 10mm, you'll need a deep socket 10mm) then the housing. The thermostat is in the housing. remove and replace with a new one.

Thermostats usually connect to another hose so you should be able to replace it. Just go to autoaone they should have whatever you need.

can please give us a clearer info regarding on this..?
