I'm finally buttoning up my Edelbrock 1406 with 2131 manifold and Skip White HEI upgrade project in my 75 Wagoneer.
Discovered that coolant is leaking out somewhere near the water neck/thermostat housing once I regasketed, sealed, and reassembled.
I have a brand new cast iron housing on order just in case the current housing is cracked or warped. The currently installed housing is original to the engine.
My actual question is, what do I do with the CTO switch on the housing? Could it be peeping coolant out? Do I put caps on the 3 vacuum line ports? Do I remove the switch and "bung" it? My Jeep does not have to undergo emissions testing, and therefore I removed much of the emissions equipment.
