How to pressurize your radiator?
you did not state the problem
most radiator shops will do this for free. If you want to do it yourself you'll have to buy a kit or see if you can rent one at a parts house. But how it works is you take your cap off and put the right size cap on hook a hose to it and pump up to the psi on the radiator cap you take off and look for leaks
Radiator scaled up. Some raditor shops can descale them , but depending on what type it is. Possibly the water jackets in the cylinder head can also be scaled up.
the heat from your engine will pressurize it. Is their a leak somewhere? You shouldn't need to pressurize it by yourself.
what degree thermostat did you put in? that make it go hot then cool
