You guys like a mystery? Below is a quick overview. My questions are at the bottom.
Problem: overheating. Symptoms: radiator cap cold, lower radtr hose cold; also there had been a squeaking noise for a while.
I installed a new thermostat and a new water pump and flushed the radtr.
But it is still overheating and the radtr lower hose is still cold. I disconnected the lower hose from the radtr and found that water runs freely from heater hose through water pump and out the lower hose: no blockage.
I pulled the radiator to test it with a hose. Water runs freely through the radiator from the cap and top inlet, out the bottom outlet. No blockage.
New issue: After flushing the radtr I found globblets of reddish trans fluid floating in the radtr and in the top radtr hose. Earlier those lines fittings had been leaking so I put sealer on the threads and re-tighted where the trans lines enter the radtr.
I think there might be a couple of things going on. MY questions:
1. IS it possible that I broke the trans cooler so it now leaks into the radtr?
2. Why is the lower radtr hose still cold and the engine still overheating?
3. Could these two problems be caused by one bad radiator?
Many thanks, Mike
