Cooling system pressure test

[BlackGT97]

any ideas on how i can manually pressurize my cooling system to find my leak?
thanks.

you could take the upper radiator hose off and take a water hose and blast water through the lower intake manifold where the thermostat was. not sure how well that would work and then after that you would have to do a complete flush.

Those things work great.
