Valerian 0 Posted March 2, 2006 these are the possibilities..... blown headgasket cracked cylinder head cracked cylinder block Faulty expansion tank cap Faulty thermostat or air lock in the cooling system somewhere I've found that a common reason for the temp guage to read low is because the two wires to the two coolent sensors are connected the wrong way round. However.....from what you describe.....may well be headgasket failure Quote Share this post Link to post Share on other sites
