The ex-mechanic recommended an head gasket sealant bottle as a remedy for the "oil leak" that needed to be mixed with water and applied thru the radiator. My husband took 2 days for the whole process to allow all the water to evaporate/drain. Replaced the thermostat and refill it with premixed 50/50 coolant. Event replaced the plastic "T" pipe that the cap screws on and the big hose connects to and change the cap also.
Yesterday, we removed the fan sensor and checked it had son "resistance" between the connector pins and clean it shinny the re-installed it with silicon tape. Second, hot-wired the fan and it worked on both sides. Things I found out to do in the internet.
The fan turns on almost immediately when the car is cold because the water takes seconds to get warm to touch. I know because I put my finger where the cap goes when the car was cold. Also, I can see inside the cap hole, the water being suck for a few seconds, then it comes up to the top, then gets suctioned again.
After driving it for awhile, the water reservoir is literally boiling and shooting water from a side vent.
