I changed my turbo over today and after bolting everything back on, i can now hear a bubbling sound while im driving thats sounds like its coming from in the dash/ under hood? Doesn't happen constantly but every 10-20seconds.
A shit tonne of coolant came out of the water lines of the turbo, so once they were bolted back up, I poured coolant and water into the top of the radiator. I'm thinking the bubbling has something to do with the way I have done that.
The car does nt seem to overheat, but then again I haven't driven very far.
