1997 Ford Aerostar thermostat

Does anyone have a diagram where the thermostat is on this vehicle? I think I found it (not a true mechanic). There is a hose that runs from the radiator back and down. It is attached to something with two bolts. Is this the thermostat?

Sounds like you found it. Follow the hose to where it mounts to the engine. And yes, most thermostat houses are secured with two bolts. Be sure to replace any gaskets and make sure the mating surface is clean.

Thanks so much. Do I have to take the hose off or just unbolt the thermostat?

Remove the two bolts and the hose with the thermostat housing will come off with it. There will be a little antifreeze spilling, but don't worry about it.

It will take you all of 5 mins to replace.

Also, sometimes loosening the hose clamp at the radiator end will allow the hose to be rotated slightly for ease of work (just be sure to retighten when finished). Be sure you can get the outlet in a position to get the surface cleaned as "Hot" mentioned.

I'm assuming the hose(s) are in good shape? Might be a good time to replace if they need it.
