Radiator cap 52 F1
Hi guys
Only had truck on road half dozen times. All occasions (after warmed up) truck runs at 190. Upon getting home engine is dry and no antifreeze under truck. I have no clue what radiator cap is on it. There are no markings. I believe the truck should have a 4 lb cap and having the wrong one could cause damage. Should I buy a new one or based on the history I just explained, not worry and buy new when I come across one. Btw I've tried local Napa and other auto stores and they don't carry 4 lb cap. Thanks Andy |

I wouldn't sweat it. If the temp gets up above 200 or so and don't lift the cap then I would investigate it.

Re: Radiator cap 52 F1
I know it is an old issue but I've never run pressure on mine. Been running it for 67 years and it has never once overheated. Removed the bottom seal on the cap and hooked up a recovery system. Left the top seal in place. Works like a champ. I do have to add a little anti-freeze occasionally. 160 degree thermostats.

Anyhow, Stant part number 10208. (4# cap) I'm running 180 degree thermostats. Temp sits a little over 180 usually. If it's really hot outside it may get up to a little over 190. Last edited by 1948F-1Pickup; 02-21-2017 at 09:43 PM. |

Re: Radiator cap 52 F1
Also running 180 stats. and 4# cap. Usually runs about 180-190.(Even with a/c) I understand that's the best temp to run these flatties.

Re: Radiator cap 52 F1
Most old caps don't seat down on the bottom seat in the radiator
filler neck. The bottom rubber seal needs to hit before the under side of the cap hits the top of the filler neck. I put a rubber washer down in the bottom on the brass seat. For the guy that put on the recovery tank and removed the rubber on the bottom of the cap, this is not necessary because as the engine cools when the temp gets below 155 a vacume is created in the engine. This vacume sucks the water from the recovery bottle into the engine as the jiggle valve on the bottom of the cap opens. G.M.

Re: Radiator cap 52 F1
I didn't remove it for recovery purposes. My radiator is as old as my engine and with any pressure it leaks a little. Removing the lower seal cured it. The engine and radiator have been carefully cared for all their lives. There is no build up in the block and the inside of the radiator is shiny copper.

Re: Radiator cap 52 F1
I had my original radiator at a repair shop to have a couple leaks repaired. The shop owner also has several classics. He made the repairs and told me that these old radiators should NEVER have more than a 4# cap. Hope this helps!
