About 2 minutes after the guage indicates normal temperature, the sound of a "pop" resembling that of a gallon can popping out a dent when filled with air comes from the front of the engine. After replacing the water pumps with Skips, the engine does not overheat at any speed. Upon cooling down, I can hear the same "pop" somewhere up front. Your comments would be appreciated. Thanks!

It might be the top tank on the radiator flexing. Are you running a pressure radiator cap? My radiator guy added two braces between the front and back of the top tank when I told him I wanted to run a 4 lb. cap. Look carefully at the shape of the front of the tank when cool and then after you hear the POP.

Sporty, DeLuxe hit the nail on the head for you. Early radiators were not engineered to use pressure caps. When freshening up one of these radiators, a good radiator shop will, upon request, solder internal supports to prevent oil canning, which will eventually cause a leak at the solder joints. Alan

my 40 running a NOS radiator with Skips pumps and following his instructions, 4 lb cap, etc did the same thing, except it buldged out and has not yet returned to normal--I left it alone-if it ain't broke don't fix it.

I was thinking about hanging a coolant tank, and NO pressure cap, this way the coolant will not get lost and keep the radiator full and no radiator problems ? this would be a tempory tank that easily be removed if need be,placed on the inner fender panel what are your thoughts on this,???? I also have Skips pumps and have bought his valve but Have NOT Installed the Valve, as of yet,. I drive my car, and really do not loose too much coolant if not used in much traffic,as loog as it stays a little cool, 37RAGTOPMAN at some of the car shows have seen the aluminum tank on some of the cars that are driven to the show,

Deluxe40, Alan, Alan & 37RAGTOPMAN, I am running a 4 pound cap but appear to have no leakage at this time. The extra radiator supports and an expansion tank sound like good ideas. Thanks for your comments! Alan

We should find out who's the oldest! I'm 70 but most likely the least knowledgeable about old Fords. My first car in high school was 1946 Mercury Convert, then a '49 Ford 2 door followed by a '53 Hardtop.

Although my name isn't "Alan", us Geezers should form a club of 70 Plus types. We could call it the ELDER Ford V8 Club of America. Sort of a geriatric version of the original, except instead of suggesting Marvel Mystery Oil for all our woe's, we would prescribe Geritol.
