uaquin Posted October 18, 2010 Report Share Posted October 18, 2010 Maybe a faulty water pump or a blockage somewhere? Link to comment Share on other sites More sharing options...

PRIDEneverDIED Posted October 18, 2010 Report Share Posted October 18, 2010 did you bleed the cooling system properly when you replaced everything. Link to comment Share on other sites More sharing options...

sobercuban Posted October 18, 2010 Report Share Posted October 18, 2010 did you bleed the cooling system properly when you replaced everything. yeah sometimes air in the system can keep it from functioning correctly. Have you ruled out a head-gasket? Link to comment Share on other sites More sharing options...

sobercuban Posted October 18, 2010 Report Share Posted October 18, 2010 i haven't ruled out a head gasket' date=' but i dont really know what that means, explain further please.[/quote'] are you losing coolant as well? If you have a blown head gasket, coolant can escape through the exhaust. Getting any white smoke ? Link to comment Share on other sites More sharing options...

TheFedornator Posted October 18, 2010 Author Report Share Posted October 18, 2010 ok, so there isnt any white smoke coming from the exhaust, everything seems to be running fine, it just seems ike the water is circulating like its suppossed to, i started the engine and removed the radiator cap and after a few minutes bubbles began to come out, does that mean i have air locks?

PRIDEneverDIED Posted October 18, 2010 Report Share Posted October 18, 2010 I havent worked on anything German since my VW which was a pain in the ***....this is the best thing i could find on flushing the coolant, go to the bottom and make sure you keep a very close eye for air bubbles http://www.pelicanparts.com/bmw/techarticles/E36-Coolant_Flush/E36-Coolant-Flush.htm Link to comment Share on other sites More sharing options...

UFCCagerattler Posted October 18, 2010 Report Share Posted October 18, 2010 Don't run your car with the rad cap off. Take it to a mechanic and he can pressure test the rad in 2 minutes. Link to comment Share on other sites More sharing options...

joshdfs Posted October 18, 2010 Report Share Posted October 18, 2010 turn on your heater when u drive This' date=' sorta. run your car in the driveway til it gets warm (not hot), then remove your radiator cap, and turn on your heater full blast, once the water in your radiator disappears slowly refill it and keep everything running until you can see water circulating through the radiator. Close your radiator before turnng off your engine and you are chock full. To check for head gasket damage is simple. Check your dipstick and the inside of your oil cap for any milky colored tarry type substance or white foamy bubbles. Also while you are filling your water and you see it circulating look for any milky oily looking water or a buildup of foam that will have oil on it. any of those signs and I suggest getting a tube of [i']Liquid Glass[/i] from the part store, running it, and selling the beamer!

Okoye35 Posted October 18, 2010 Report Share Posted October 18, 2010 Not sure if this has been mentioned yet... It could also be your heater core. It needs to be flushed every so often or they completely clog up and won't allow circulation. If your car is still having problems after everything else you have tried I'd suggest having it flushed. If it is completely clogged, flushing it will not work and it will need to be replaced. Link to comment Share on other sites More sharing options...
KungFuMaster Posted October 18, 2010 Report Share Posted October 18, 2010 I would suspect your pump is not working just like uaquin have stated. For trapped air, you must bleed it......by using the bleed valve. And if you don't know how to do it, a friendly mechanic would be able to do it for you. Try asking a friend first before going to the shop. Link to comment Share on other sites More sharing options...
