Hi ive changed the radiator with a brandnew one also new water pump, new thermostat flush the system but my car over heats when idling and driving around, even the fan comes on, my car splutters and bubbles from the resavoir tank boiling water shoots out, i thought it might be a air lock ran the car for 45 minutes and still bubbling , the rad pipe on top is bubbling when i feel it , return pipe is not flowing properly and steam is coming out continously.
any help or advice would be grateful ive checked for mayo in oil and water for oil both is clear.
Help!!!
