I'm completely stumped and so is my local garage. I have a 1999 Ford Ranger XLT 3.0L Flex fuel with only 77k. We can't seem to get the radiator to stop overflowing the reservoir tank. The coolant will go into the overflow tank and not be siphoned back into the radiator. This usually only happens when it is really cold out, below 20 degrees. This also causes a no heat in the cabin of the truck until, what I can only assume is enough pressure or heat from the engine to open up the t-stat and let whatever coolant is left in the radiator circulate into the heater core and then i get heat, really hot heat. I had the thermostat replaced and the radiator because it was rusty inside from sitting for a couple of years with only a few hundred miles being put on it a month (this was my dads truck, and after he passed away it didn't get driven but a few times a week by a neighbor to keep it running)
Once the truck cools down, I can siphone the coolant out of the reservoir about 2/3 of a gallon and open up the radiator cap, and dump it back into the radiator to fill it back up.
The shop has flushed the coolant system 4 times to get the coolant to not look like lake water. They thought that the pressure in the radiator was a little high and that could be caused by a head issue, they have run every diagnostic test to see if the head gasket or head is bad, and it passed everyone. When the weather warms up, it runs fine for a week, but eventually it will overflow again. I'm pretty desperate now. With only 77K on the engine, I would love to keep it running as my dad gently drove it and it is in really great shape.
