Coolant Temperature Sensor

I did mine that way. You need to make sure that the new one has a new seal on it, and is ready to go. A third hand to put a finger in the dam might help. But actually I lost very little coolant - it's a small hole and will have to gulp air back in as the coolant comes out, so it is not as bad as one might think.

Thats my experience. You won't lose much, just have the new one ready to go when you start taking the old one out.

Make sure the engine is not hot (though slightly warm is probably best). Leave the radiator cap on.

I did it with draining a bit of coolant. My problem was after installing the new `brass` one.......the old one was plastic......the new one I put in was faulty. My luck goes that way :( . Dan.

I replaced the CTS on a SL2 without any problems. Can't remember much coolant coming out - car was cold.

The new sensor should have sealant already applied to the threads.
