Heard a weird popping sound coming from the hood while sitting idle in a parking lot, after about a 20 minutes drive. Pop the hood to find that it's coming from the coolant tank. An intermittent popping sound. Any ideas on what's going on? I've been having heating problems, which may be related to a bad ground I think (hot ground cable. funky charging voltage), causing faulty gauge readings. Coolant system has been bled twice with a pressure tester, I believe I've gotten all the air pockets out.

TIA.

thermostat to turbo stuck shut? sounds like your turbo is getting too hot and boiling coolant. lso mke sure your aux water pump is running.

Turbo thermostat is new. changed out like 2 weeks who. Didn't test in water though... maybe ill run without.

pump works cause i can always hear it run after shut down.
