What is behind this cover? Is it sealing off the timing chain and then open holes in the block to circulate the water in the engine? Does the water pressure only come from the jet pump?
Thanks for the reply - So there is a timing cover behind that plate. Good. The kid I bought it from said it would run cold all the time so he said someone recommended to put valves on the lines to regulate it. I have been reading up on it but sometimes people can be confusing. Do you recommend putting a pressure relief valve on the intake hose and set it at 20psi - Then have both outlets on the thermo housing dump overboard? Then take plug out of manifold next to housing and feed the headers?It's not really sealing off the timing set, as the timing cover does that.
It's an adapter plate to eleminate the automotive water circulating pump, and to plumb cold water from the jet pump into the front of the engine.
Just FYI, you should never limit the flow out of the engine. Limit flow at the pump into the engine to desired running temps. Limiting flow out of the engine can (WILL) over pressure the cooling system, and push out head gaskets and intake gaskets.
