Need clip to use on new coolant temp sensor. Had to remove to remove bad one.

Well let's see, I reckon we have to assume you mean the retainer clip that holds the actual sensor in place at the thermostat housing on the 4 cylinder engine? .... Any of the auto parts stores have the CTS so nothing special about that, however when I looked I didn't see the clip with any of them ... Try salvage yard (Ford Ranger some Mazdas should be same) or get dealer to order one... Good luck!
