Ok i know the coolant level sensor is the block looking one on the radiator....

There are 2 on the engine that have me confused....

one is located on the rear Cyl Head and simply has a one wire plug going to it.

the other one is located kinda under the thermostat housing on the firewall side of the lower intake.

has 2 wires and plug to it.

my problem is my coolant temp sensor is messed up and im not sure which one is which.

any help is welcome

Dave

one under the T-stat is for the engine and ECM and the one in the rear head is for the temp gauge in the car....

both CTS's but for diffrent things...
