This reminds me to let you know. BEWARE !!!

The temp sending unit is located on the thermostat housing. It is one of the highest points on the engine with coolant. If your coolant level drops below the sender, your gauge will not raise up, because it needs coolant touching it to send an accurate signal to the gauge.

Your gauge will usually drop down a bit, and make you think your engine is actually running cooler.

So learn your car, and know where your gauge normally operates at. Look at it often when you drive.

And make sure your radiator cap holds 13lbs, they do get weak as the years go by. ( I almost lost a freshly rebuilt motor in my '65 Mustang due to a cap that was supposed to be 14lbs, but only held 7lbs).

All of the above happened to the Mustang.
