    Losing coolant after cam swap

    I completed a cam swap last month and noticed that it was losing coolant every couple days, needing maybe 1/2 cup or so, just enough to make we worry about it. I figured it was just purging air out of the system, but now a month later, it is still losing fluid at the same rate. I installed new water pump gaskets when doing the swap, kept the stock hoses.

    I have looked all through the engine bay over and over, and see no leaks, no dripping under the car (hot or cold), no steam...

    Any suggestions where it could be leaking??

    if you cant find the drip your best bet is to "pressure check the system". You can pick up a tester from local parts store, may even be able to borrow one, with the system cold you attach it to the rad, where the cap goes and just pump air into the system and see if you loose pressure and or if coolant comes seeping out.

    Thanks for the tip. Turns out this was a simple worn out radiator cap. I left it off the car for a few days during the swap and I guess the rubber dried out and started leaking under pressure.

    New cap, $4, problem solved!
