capnfred Posted February 23, 2009 Share Posted February 23, 2009 Have you checked the compression for a possible blown head gasket, is the fan running at the correct speed, have you done a pressure test on the cooling system to see if there is a problem holding pressure, have you checked the cooling system cap,,, these are a few of the other things that could cause an overheating problem. good luck Capn Quote Link to comment Share on other sites More sharing options...
eatingupblacktop Posted February 23, 2009 Share Posted February 23, 2009 In addtition to what capnfred has suggested, check the coolant hoses. The rad could be blocked. Quote Link to comment Share on other sites More sharing options...
kingjack133 Posted February 23, 2009 Share Posted February 23, 2009 did it start overheating after the new water pump? If so, i would bet that it is an air lock. Quote Link to comment Share on other sites More sharing options...
eatingupblacktop Posted February 23, 2009 Share Posted February 23, 2009 Was it overheating before or after the work you've done? I understood you to say that you made the changes because it was overheating. Quote Link to comment Share on other sites More sharing options...
manest Posted February 23, 2009 Share Posted February 23, 2009 I hate to be the bearer of bad news, but it is most likely a blown head gasket :( I'll go as far as to say it is probably the #6 cylinder. Don't ask me how I know!! Quote Link to comment Share on other sites More sharing options...
DUBBCEE Posted February 23, 2009 Share Posted February 23, 2009 Agreed #6 is a likely suspect. Do some of the test as stated above or even test the anti-freeze for exhaust gas. Any one who has owned an 1992-93 ES with more that 150,000 miles on the dash can probably relate. Quote Link to comment Share on other sites More sharing options...
capnfred Posted February 23, 2009 Share Posted February 23, 2009 mine is a 93, with 179k on the clock, but I do not have a clue as to the maintenence history on it. Any insight as to why number six would be the commen location for the blowout..... the early VW engines had a problem with number three burning valves, but that was because the oil cooler was in theway and block the cooling air to it.
