Jay85 Posted May 3, 2014 Share Posted May 3, 2014 (edited) Take the thermostat out n try it dude, sounds like it's jammed shut! Also connect the fan directly to a 12v feed to check it's working Edited May 3, 2014 by Jay85 Quote Link to post Share on other sites
brendonware Posted May 3, 2014 Share Posted May 3, 2014 if its not the thermostat maybe you have a broken water pump? Brendon Quote Link to post Share on other sites
smb2011 Posted May 3, 2014 Author Share Posted May 3, 2014 I checked the fan it works fine il take the therm out and test it in hot and cold water and see but i thought the fan would still kick in it the temp goes to high ? Thats whats confusing me its not kicking in even when i change both switches Quote Link to post Share on other sites
richardc9052 Posted May 3, 2014 Share Posted May 3, 2014 Put 12v to the fan. But to be honest if the coolant is bubbling over that's generally a sign there are combustion gasses entering the coolant somehow Quote Link to post Share on other sites
smb2011 Posted May 3, 2014 Author Share Posted May 3, 2014 It gets hot and starts shooting out the top hot air coming through and fan still hasnt come in weird one Quote Link to post Share on other sites
richardc9052 Posted May 3, 2014 Share Posted May 3, 2014 How long after you starting the engine from cold does it start bubbling? Quote Link to post Share on other sites
smb2011 Posted May 3, 2014 Author Share Posted May 3, 2014 Put new therm in and shes spot on now weird because hot air was coming through before Quote Link to post Share on other sites
Jay85 Posted May 3, 2014 Share Posted May 3, 2014 Hot water for the matrix comes from the engine side of the coolant system! Glad it fixed!! Quote Link to post Share on other sites
