Bubbles in rad HELP!

[MoparMike1974]

Let it sit overnight, pull plugs then turn over slowly by hand. See if any coolant has collected in a cylinder. You should be able to see a plug that has been steam cleaned but if your plugs are fairly new and clean it can be hard to detect.
Put a pressure tester on the radiator and pump it up. See if it holds.

1st. and easy thing 1st. Top off radiator plum full. Disable ignition by pulling coil wire, whatever. Have a helper crank engine over while you watch radiator filler neck with cap off. If it raises up and runs out you have compression leaking into cooling system, this will show anything MAJOR wrong 1st. Hope it helps.

I will try that for sure. Going to check compression tomorrow as well, thanks!

If its a pinhole,good chance you wont get coolant into cylinder.
Can leak compression, but not water.
Doesesnt hurt to check cylinders for coolant. Again, at least you where to look when you pull it apart.

Ended up being tiny pinholes in the water pump hose. New hoses and she's good as new! Thanks for the help everyone.
