Toyota: engine / cooling system diagram, engine cooling system, radiator hose


Question
I'm hoping you might be able to provide me with a diagram or description of where the thermostat is in my '94 Toyota pick-up. It is a two-wheel drive, 4 cylinder model. I've changed the thermostat before, but when I looked for it today I couldn't remember how to identify it, and my manual was no help. I know roughly where it is on the left side on my engine block, but can't say I know exactly where it is. Could you please give me a pointer or tell me where I could find an diagram online. Thanks.

Answer
Hi Corey,

I haven't done a 94 model Toy, but in my old 74 Luv truck and my 65 Austin Healey both, the thermostat is located between the top radiator hose and the engine block.  Its a roundish/dome-shaped housing attached to the top of the engine.  Remove the top radiator hose at the engine end, and remove the thermostat housing bolts, clean the area, and reinstall the new one.

Hope this helps,
