radiator cap adaptor

[baxter]

I have a leak in my coolant system and I'm looking for a radiator cap adaptor for a pressure tester so I can locate the leek. If anyone knows where I can find one it would be helpfull thanks in advance.

It might be possible to fab one up using an old radiator cap and a valve stem from a tubless tire.

They are usually part of the pressure tester kit.

Stick a hose nipple in one of the unused holes (or a used one for that matter...) in the intake jacket by the thermostat. Hook it to one of those inexpensive pressure regulators (make sure it's a regulator, not just an orifice type), hook it to the glad hand if the engine is running, or your compressor if not, set it to ten or twelve pounds, and let 'er rip.

Most of the nation wide autoparts places will rent special tools. You should be able to rent a cooling system pressure tester really cheap. Do not hook up to a high pressure air source as all kinds of really bad things can happen.
