[Healeys] Over heating and adding additional core tubes to theexisting radiator

I am jumping in on this subject a bit late, so I do not know if Bob has a thermostat that incorporates a moving sleeve for the bypass or not. Either that type of thermostat or a fixed blanking sleeve for the bypass would be essential for this climate. Or any climate for that matter.

There is not enough cooling capacity in the stock radiator to handle hot climates and have to stop and go because the temperature does not go down only up.  So the next step is to re-core the radiator.  The local radiator guy knows the problem and for $500 will provide new core using the old tanks which will give at least 50% more cooling capacity.  This is a SKI purchase.  Spend the Kids Inheritance.  Then I will think about wrapping the exhaust manifolds and headers to stop vapor lock.  What do you think about Push and Pull?  Take off the engine fan?  By the way, I know the engine machine shop boiled out, oil bathed, everything in the engine during his machining of the engine to bring it up to specifications.  He knows what to do.  The only modification is the 20 over pistons.    Why do other Healey’s with a stock radiator not have this problem, who knows?  Bob   From: Perry <healeyguy at aol.com>

There is something else amiss in the equation. Perry  Sent from Mail for Windows 10  From: Robert Begani

Subject: RE: [Healeys] Over heating and adding additional core tubes to theexisting radiator  Hi Perry:  I do not remember the CFM, however, it is the Hayden Fan offered by Moss with the largest diameter to fit the radiator.  As a pusher it really pushes air through the engine compartment at low speeds and standing still. I still have an original Texas 6 blade fan on the engine.  As I was searching overheating problems, one reference indicated that is not recommended as they act against each other.  Bob  _______________________________________________
