So i filled up the radiator.

No pressure radiator cap.

The problem is my pepcock on my brand new radiator is leaking. High pressure caps are available in pressures ranging form 19 to 32 pounds. Cost was only 3 or 4 dollars. This may help you find leaks or determine if the radiator cap has gone bad.

Let s take a pan of water and heat it up. Most radiator pressure caps keep the system pressure at 16 psi so the engine coolant can get considerably hotter without the fear that it will boil off. The water heats up and boils and 212 degrees. When i removed the radiator cap there was no pressure on it.

I m not losing coolant. To make a no pressure cap you want to remove the inner seal and fully tighten the cap so the outer seal keeps the coolant in the radiator and the overflow tank. They should not be used on passenger cars. The outer seal seals the cap to the radiator.

It might simply be that the cap is no longer holding the pressure correctly. Sometimes its hard to find a correct radiator cap. So i replaced the radiator cap. I can drive my rig for hours and nothing.

On the other hand if the pressure was allowed to increase above 16 psi the cooling system including the hoses and. Find radiator caps with 0 psi maximum pressure psi and stant cap logo and get free shipping on orders over 99 at summit racing. My dipstick shows no sign of coolant. The easiest way to fix this problem is with a new radiator cap.

I m at my wits end. The cap pressure rating has nothing to do with regulating your engine coolant temperature nor will it make your engine run cooler. However you want to be sure that the problem is the cap and not in another part of the system. Now i don t know what to do.

If you have a radiator pressure tester then you can inspect the cooling system on your own. Now after running the engine for 15 minutes or so i can remove the radiator cap and there still is no pressure on it. High pressure caps are available for open and closed cooling systems. No pressure but it gets up to.

Visually inspect that cap to make sure the spring moves freely and there is no debris or corrosion under the cap. The cap on the right has been mangled to do that. I installed the stat spring side down so thats okay. I bleed the system.

Sometime back i found one available at napa stores they may have to order it in from the warehouse but last i knew they had them. Pressure testing the radiator. My coolant shows no sign of oil. I thought that it might be because the radiator was only 1 2 full of water.

You will also want to check the cap if you begin to have problems with the cooling system. There is one coolant cap that is quite different others. High pressure caps are made for use on race cars only.
