July 23, 201114 yr Hello all, I own an 85 GL Wagon HiLo (Vin 5) with 120,000 miles on the speedometer. I am having an issue with the vehicle overheating. I installed a new water pump when I changed the tbelts. The car did not have a thermostat so I installed one of those, correctly according to the Subaru service manual. I also installed new intake manifold gaskets, sanding and scraping the heads and manifold clean, to keep the oil and coolant separate. I cannot figure out why the system is not working properly.

July 23, 201114 yr do you have any cold spots in your radiator usually it is sign of radiator being plugged up and if it is thats your problem...
July 23, 201114 yr Author Soobies, The radiator has been installed new by the previous owner, made in mexico, and I did not have a coolant system issue before I stated this repair. I removed the thermostat, it is 100 degrees F in Kansas City, and installed a new gasket. The over heating issue has evaporated. I still need to determine why the thermostat is not opening, and yes, the thermostat was not upside down. Any advice is greatly appreciated.
