1948 Cadillac Hearse Radiator Cap Pressure?


Recommended Posts

I have an e-mail contact with a funeral home in Canada that uses a 1948 Cadillac hearse regularly. He needs to know what the radiator cap pressure rating is so that he can replace it.

I figure that if he needs that, what h really needs is a service manual on his hearse. I have a 1953 Chilton that covers Cadillac but it doesn't give cooling system pressure specifications. I presume that the hearse will be a 75 series.

Replying here is best, of course. You can copy the guy, Glenn, at Monk Funeral Services, monkfunerals@bellnet.ca if you like.

The best that I can determine is that the car should use a 180 degree thermostat and a 13 PSI radiator cap.

If your weather is generally mild (under 85-90 degrees), I would consider using an 8 PSI cap, less pressure on the radiator and heater components.

Both of my old Chryslers (1955) use 14 PSI caps, I have actually had a 8 PSI cap on one for years, without any overheating.

Take a look at Stant.com for more information.
