Radiator Cap
What does the pound size on a radiator cap stand for? I have a 16 pound on my new radiator now but I saw in the overhaula manuak it said either 11 or 13.
Thanks

That is the pressure in the radiator and cooling system. If the pressure reaches the max the radiator cap will release the pressure to keep from rupturing the radiator or other parts in the system.
The pressure is in pounds per square inch and is necessary in the system to raise the boiling point of the coolant. Jim |

Adding a higher rated cap may sound like a good idea, but if your rad is old, or if your heater core is original, I would advise against it. A few extra pounds can create a bunch of stress on old joints, and make a nasty green puddle under your rig.
Been there, done that, and I think I may still have the second degree burn scars to prove it too. |
