I own a 1992 SC400 with 140000 miles now, I bought a new expansion tank thinking it was cracked but a week later I notice coolant on the top of the tank. It must be the coolant tank sensor.... looked for install tips but could not find them... is there anything special I need to know to change it?

 

well to b honest its plain and simple get the old sensor out and the new one in nothing crazy to watch for or do.. but make sure its that sensor and not he tank or rad.. and i literally just bought it for the same car but diff reason heres the part # 16485-50021
