Thermostat Orientation on 20R engine

Nov 26, 2005 2 Replies

Does anybody know the correct orientation for a thermostat on a 20R engine?



In other words does the spring end of the thermostat go towards the cylinderhead/engine block (down) or towards the radiator (up)?



Thanks for any help.

It goes down toward the block.

Thanks Chuck.

That's how I put it in. And now (thankfully) the engine stopped overheating which it spontaneously started doing immediately after I installed a replacement igniter on the coil. But when I took the old thermostat out of the hot engine, it was closed.

For the life of me I can't see how one can be related to the other but in my experience there's usually a relationship when one thing gets changed and it is immediatley followed by another change (failure).

Thanks again for the help.
