The ects in located on the drivers side up towards the top and into the side of the block has a small 2 wire plug,make sure when you buy this that you tell them sensor and not switch as they look the same,do this with the engine cool,remove the coolant tank cap to relieve pressure and coolant loss will be very small.

check coolant temp sensor located at driver side end of cyl head. remove sensor and check or cracks. also check connector for corrosion. if cracked, go to dealer for replacment. they eill sell you a new designed metal sensor to replace your cracked plastic one. dont buy aftermarket, they will not be accurate. cracked sensor will cause eng. to run rich. may start ok cold but not when hot.
