Subject: Re: Coolant boiling/gargling sound when the engine is turned off by BillH on 2012/10/6 17:45:41 It can gurgle when parked hot BUT this is usually coolant going from the header tank back to the reservoir. Gurgling under the T/B sounds like there's air in the system. It helps to jack up the car or park on an incline to put the radiator higher than the engine but - with the cap off and the engine warmed up enough that the thermostat is open, with the car running, open the throttle to 1500 or so and fill the header tank up to the cap, then put the cap on wothout releasing the throttle. Release the throttle after the cap is on. This helps push the air out. Ypu can also drill a 1/8th hole in the thermostat which will help purge the air. All this will work IF the mechanic did the gasket correctly. Ypu should probably have the system pressure tested, possibily Autozone or whatever would do that. I don't have a pressure tester buy feel free to stop by if you get up this way. Are you going to be at the racetrack next weekend? |
