Re: 1950 Packard 288 Auto overheating HELP

Some owners of these 22nd/23rd series Packard have fit electric fans in front of the radiator to provide air flow at slow speeds and while idling. The fan is controlled by a switch usually mounted under the instrument panel. These fans are available in 6-volt versions. They are not too difficult to install. They will cool down the engine.

Some owners also install an after market flex fan. These come in different sizes to fit a variety of applications. These fans will also increase air flow at low speeds and have less resistance to air flow at higher speeds. They too are readily available in the after market.

What temperature rating does your thermostat have? Usually, a 160F is recommended. Some owners have installed 180F thermostats only to replace them later. The 180F thermostats limit the operating temperature to a narrow range on the high side.

Have you double-checked your radiator cap? Make sure you have the type that fully seats/seals in the neck.

One more thing. Does your coolant circulate through the heater core, or do you have it shut-off? Circulation through the heater will give you a little more coolant capacity.

Good luck and let us know how you solve the problem.
