I replaced my radiator cap. The one before the rubber on the other one i had was dry rotted and spring didn't flex the best?

I bought a new one and put it on so i have no way of testing and also the temp would get up to 240 degrees.

But i have no way of testing and my air duct part of the paneling was hanging so getting a bigger washer or going to the junkyard and picking up a new one mine i kinda torn.

Do you think this will make it run alot cooler now.

 

cooling system when it pressurizes it is going to find the next next weak spot- if there is anymore. you replaced to cap- old was dry rotted. if everthing else will hold up then you need to make sure to get the best air flow across the radiator.

 

Ok Sounds Good But do you think this will fix my close to overheating i replaced most hoses also done the thermostat and all the good coolant flushed twice radiator is clean uhm, let's see and new coolant. Gm's 50/50
