I have a 2000 Jetta TDI and have flushed the coolant, replaced, burped, continual interaction with the car for past 2 weeks... yet is still over heats unless i run the heater.
i really need some help.
When i flushed the system I opened up all i could and the bottom drain allowed all fluids to leave via gravity. ran distilled water through with engine running until it ran continually through the return like to over flow bulb. then drained again and gravity fed G12 until stopped flowing and started motor. continued to fill until ran continually through return to bulb. even stood squeezing hoses for an hour burping bubbles out.
yet, my 50 mile commute finds me at temp (190) after 5 miles of driving, then after my midpoint (25mi) the needle rises quickly to the 260 mark. then i hit the heater and it starts going back down. heater on (190) heater off (overheat).
its driving me nuts.
I have: done all of the above as well as look for leaks (finding none), and clean temp sensor connection and ensure good connection. Radiator fans are working, water is in constant flow to bulb. G12 coolant.
I have not: tested or changed thermostat
thank you in advance
