My Buick 2003 Rendezvoux has intermittent overhearing issues. I have replaced the water pump, radiator, thermostat, water temp sender, and the radiator cap. This was done by my local mechanic.
I have ordered another thermostat, a "fail safe" one that he suggested.
He recently replaced one of the coils for the 2-5 cylinder that was not firing. Drove fine, went to town about 11 mile away and back. My wife drove it to 2 meetings, no issues.
We decided to drive it to South Haven for grocery shopping, but about 4 miles from home, on the interstate, the bell went off alerting to overheating. She pulled over, and I examined under the hood. Pulled up the flap on the engine coolant reservoir and it started to gush out. The radiator cap and area was cool to the touch. We waited and then drove home, getting off at the next exit, and took the back roads if we had to stop again
When we got home I popped the hood and engine radiator cap was cool to the touch, but the fans were running for the radiator. It started to get hot when we drove down our driveway.
Afterwards, next day I checked the coolant reservoir and it is normal. Took off the radiator cap and radiator is full of coolant.
The hose between the reservoir and radiator seems to be very soft and pliable. Could it be collapsing when trying to draw in coolant?
Am baffled as to why this happens, and it is intermittent.
Any clues?
