Can you put a thermostat in upside down?

Can you put a thermostat in upside down?

So if you put it in backwards, the water pump flow will push open the thermostat and cause it to take MUCH longer to heat up. When a thermostat is in correct orientation, there needs to be coolant flow, else the stat will be in dead zone and take longer to heat up.

What is the purpose of a jiggle valve on a thermostat?

These thermostats are equipped with a jiggle pin valve in the flange. This valve prevents air lock from occurring in the cooling system by allowing trapped air to escape while also reducing coolant leakage through the flange. Air lock and leakage hinder the operation of a thermostat during engine warm up.

Where is the thermostat located on an engine?

The thermostat provides control for your engine’s warm-up period. The thermostat is located between the engine and the radiator. This little temperature-sensitive spring valve stays closed during engine warm-up.

What happens if the thermostat is installed backwards?

Answer: A thermostat installed backward will cause the engine to overheat quickly, similar to a thermostat being “stuck closed.” Therefore, always double check that the thermostat is installed in the correct direction, and if equipped with a jiggle valve you install it according to the Factory Service Manual. Which way does the jiggle valve go?

Why does the thermostat have a hole in it?

So the sensing part of the thermostat has to be toward the engine. Coolant over the thermostat will cause it to close immediately. The temperature spring. Also, your thermostat may have a small hole with a “jiggle pin” the air out of the system. Replace tt with t (twice!) and remove parentheses to email me directly.

Which is the deep end of the thermostat?

Therefore, the deep end (Arrow C) of the thermostat always gets installed going towards, or into, the engine. (Arrow A) in the photo is the new thermostat gasket on the new thermostat, make sure to always use a new thermostat gasket if your Factory Service Manual calls for one.
