Guest fist302 Posted May 16, 2009 Report Share Posted May 16, 2009 Le sigh My 5.0 is overheating after replacing a thermostat. It will warm up fine but after about 5 min the gauge suddenly shoots up to the last line befor the red and sits around that area. This is the same thing it did the last time i did a t stat but this time it isnt going away. I have ran the motor with the radiator cap off for a long time and i have taking it on a drive and it only gets worse. The only thing i replaced was the t stat and the car was working perfect befor this. It has a new water pump, radiator, cap and gaskets. Whats up with this? Second question is, what is this hose on the passenger side firewall that is dripping coolant onto my exaust? How can i stop this leak? Here is a pic. http://i698.photobucket.com/albums/vv346/wpiner88/33.jpg Thanks Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted May 16, 2009 Report Share Posted May 16, 2009 block off your heater lines and see if the problem goes away make sure you get an ALL METAL replacement core if you get the metal plastic mix you'll be right back in there in 6 months changing that fucker again Quote Link to comment Share on other sites More sharing options...
Guest fist302 Posted May 16, 2009 Report Share Posted May 16, 2009 So the heater core is the cause of the overheating or just the cause of the leak? I was thinking it had something to do with the thermostat since the problem happened directly after replacing it. Quote Link to comment Share on other sites More sharing options...
Guest fist302 Posted May 16, 2009 Report Share Posted May 16, 2009 heater core..i can hook you up on that Il get in touch with you about that, shit i woulda went down there tonight but this happened Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted May 16, 2009 Report Share Posted May 16, 2009 you need to eliminate all leaks before chasing down the overheating issue Quote Link to comment Share on other sites More sharing options...
Guest fist302 Posted May 16, 2009 Report Share Posted May 16, 2009 you need to eliminate all leaks before chasing down the overheating issue alrighty, so may i ask which hoses are the heater hoses i need to block off? Quote Link to comment Share on other sites More sharing options...
rl Posted May 16, 2009 Report Share Posted May 16, 2009 So it didnt overheat, you put a thermostat in, and now it overheats? you either didnt bleed the system or you put the thermostat in backwards. Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted May 16, 2009 Report Share Posted May 16, 2009 alrighty, so may i ask which hoses are the heater hoses i need to block off? you should have two steel pipes that run along the intake manifold then they change to rubber hoses that run into the firewall remove the hoses and gett rubber caps and clamps for the tubes and your all done Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted May 19, 2009 Report Share Posted May 19, 2009 so what happened after you got rid of the leak? does it still overheat? Quote Link to comment Share on other sites More sharing options...
Guest fist302 Posted May 19, 2009 Report Share Posted May 19, 2009 so what happened after you got rid of the leak? does it still overheat?

Guest fist302 Posted May 19, 2009 Report Share Posted May 19, 2009 got the heater core bypassed and it didnt help. Still did the exact same thing in the same amount of time, only new info is that once it starts to overheat it seems to be letting air/steam out of the waterpump tip near were the fan bolts up. This is really getting frustrating... i need this car :doh: Quote Link to comment Share on other sites More sharing options...
rl Posted May 20, 2009 Report Share Posted May 20, 2009 As I said earlier, you either have an air pocket or you have the thermostat in backwards. Check the thermostat and/or bleed it better. Quote Link to comment Share on other sites More sharing options...

Check the thermostat and/or bleed it better. Thermostat is in correctly. Got any ideas how i can bleed the system when the engine block drain plug is totally stripped?

rl Posted May 20, 2009 Report Share Posted May 20, 2009 Let the car idle with the cap off until the thermostat opens. You checked the thermostat? It's somthing simple, it didnt overheat, now you swapped thermostats and it overheats. Quote Link to comment Share on other sites More sharing options...
Guest fist302 Posted May 22, 2009 Report Share Posted May 22, 2009 I got it somewhat stabilized but it is deffinatly still running way to hot but i needed to get to school. How bad is it to run temps up around 230 for a few days? The problem is deff with the T stat i cant seem to get it to bleed properly, im thinking there is some air leaking in the hoses that i used for the heater core bypass. Il try and figure it out but thanks for the help so far atleast i got rid of my heater core leak : ) Quote Link to comment Share on other sites More sharing options...
