If the temperature rises rapidly after you start the car, it is very likely that the radiator is not doing its job. This is usually due to an internal coating of the radiator tubes with deposits such as lime from the water. The only true repair is by replacing the radiator itself. Radiator shops have mostly disappeared, and even when they were common, boiling and rodding didn't improve efficiency. Electric fans are a stopgap. They are expensive and draw high current incompatible with old car systems. When I bought my '47, it would boil before you could get around the block. A new radiator now allows adequate cooling on very hot days, and in heavy traffic. I know new radiators are very costly, but overheating certainly interferes with enjoying a reliable vehicle.

hi how long does it take to get hot, at idle or driving . Is it really hot of just hot water overflowing,? if it overflows , is it steam or just hot water,? check temp of coolant with a thermometer 'take a reading, see what it is, always fill the radiator when running warm,? not cold. water expands, first question, I assume the fan belt is adjusted, and is the correct one, not to skinny, and maybe slipping if you can turn the fan by hand with out turning the engine over belt might be too loose, how are the water pump impellers , rusted away ? are they turning , I know it is a stupid question,but maybe slipping on shaft,? maybe new water pumps. I have a 37 that ran on the hot side, installed the correct size fan belt, fit in the water pump pulleys on the edges not on the bottom of groove, I installed 2 REWORKED water pumps, from SKIP,with special impellers I also installed SKIP's overflow valve, to pressurized the coolant system, like a modern car, you have to seal your radiator cap so it does not let the pressure out. this for the most part solved the problem, stay out of PARADES , I think a ELECTRIC FAN is like a band aid, might help but does not solve the real problem,they did not use these years ago. also check if you head gaskets are leaking, any bubbles in the coolant system at idle or running,,? a coolant system pressure checker, will tell you if the coolant pressure rises within a few minutes, I use straight distilled water with water wetter in the coolant,and water pump lube ,but not antifreeze I hope this helps ,,GOOD LUCK....!!! regards 1937 RAGTOPMAN

Can you post some photos of the engine and the fan? A photo can help us understand how you cooling system is configured so we can help you better.

Coolant expands. Are you filling the radiator right to the top? If so you are getting it too full and there is no room for expansion and it goes out the overflow..

Is the cooling fan that you installed an electrically powered one? If so, do you have room to install it behind the radiator to make it a "puller" to improve efficiency ? Did the car previously have overheating issues before the installation of this fan? Has the radiator been boiled out recently? If you have exhausted all other means to make it run acceptably cool, there are other things that can be done to make it run cooler. You can seal any gaps between the radiator and the body so that you force all of the air that comes through the grille to go though the radiator. A shroud can be made or purchased to surround the fan to minimize hot air that would be recirculated. Does the engine have 160 degree F thermostats installed. After you shut a hot engine off, heat will continue to build in the cooling system for 10 minutes or so during a "hot soak period". This is a normal condition which can be minimized by allowing the cooling fan to run for a few minutes after you shut off the engine. To enable this, you will want to route the power for the cooling through an electrical thermostat that has battery power when the ignition switch is in the off position. Please let us know of your progress in solving this cooling issue.

I have a 1936 Ford 2 door sedan . i installed a 2700 cfm fan on it a week ago so now when I drive it the temperature gauge runs at 180 degrees . This last time when I turned the car off the temperature shot up to over 200 and started dumping coolant on the ground I believe it is a stock radiator it has a front vent tube in front of the radiator where the coolant was coming out does anyone have any answers. This is getting to be a problem and I can not correct it
