Alright another over heating issue, this explanation will be long to cover all symptoms, issues and attempts of fixing from other forums. But I have read almost every other forum and post and still cannot find problem or resolve. Of course if I had money I would have it fixed already, but on a budget that is almost dry. History of car; bought from a public auction drove it home fine and to work for about a week no "serious" issues except coolant reservoir boiling and loosing water which I would just add more. But no over heating, wanted to fix this problem to have a reliable daily, so started to replace parts that lead to over heating problem. Found out radiator cap was all jerry rigged to stay open allowing it to loose heat and pressure (i am thinking so it would not overheat at auction/quick fix)and radiator opening was scared and messed with. So bought new radiator and cap, this sealed coolant system to function properly. Now it starts to over heat and loosing coolant from around water pump. So go a head and replace water pump and serpentine belt. Water pump was bad, lots of build up around "weep hole" and fins corroded. Still over heating so I replace thermostat. Still over heating so find all issues and resolve on forums to fix issue. I have checked thermostat. In boiling pot, both old and new one open up fine. I do a compression test, all cylinders 140-145. Lower than specs saying around 180. But this should not be a cause of over heating? As just worn rings. Next forums saying bad head gasket or faulty head cracked/warped. I do not think it could be this as there is no water in oil (milky liquid) or excessive amount of water out from exhaust pipe nor any visible leaking from anywhere. So I try my luck with Bars HG sealer anyways and still no luck. Find out about the head gasket leak test. I have gone ahead and did the test with the two chambered detector to get a more accurate reading. I unfortunately cannot get a confirmed positive or negative as the blue liquid is suppose to turn yellow for gasoline engines and green for diesels. Well the liquid turned green. Tried it a few more times to get better results still only turns green. Tested it with breath (as instructions explain) and exhaust pipe and can get it to turn yellow. So it does work. So not sure how to decide if I do have a faulty head gasket with the wrong color positive. Any help with this? So back to square one! Last attempt was buying the "fail safe" thermostat thinking the new thermostat I bought could have been faulty some how. Still no luck and now the symptoms are; top radiator hose gets piping hot and bottom will stay cold, not even warm. Will always start up car with hot air on funnel in radiator filled with coolant to do the "burping" process every time to rid system of any air but system will continue to "burp" up air from funnel in radiator; to the point of car reaching operating temperature but coolant will start to boil out where I will have to shut it down before all coolant is pushed out. Car cannot get more than a mile before it starts to over heat. And wont ever over heat at idle sitting, even revving up to simulate stress; only over heat when driving. So confirmed air getting in system and believe thermostat not opening correctly because of this. And no check engine lights come on and car runs and idles amazing other than overheating. I think I have covered everything if anyone can help out I would be unbelievably grateful as this is all my money in this car for transportation to make money. :( Almost broke and out of options. Thank you in advance!
have the same problem?
