m1cr08472 Posted December 13, 2012 Report Share Posted December 13, 2012 Headgasket failure would only cause the heater to blow cold if all the water had leaked out. Quote Link to comment Share on other sites More sharing options...
raj91lupo Posted December 18, 2012 Author Report Share Posted December 18, 2012 i've got hot air in it now. turned out the new matrix wasn't allowing perfect fluid flow through it. Quote Link to comment Share on other sites More sharing options...
