We have been bringing back up to specs for the last year. Last problem is the cooling system. It has occasionally burped coolant out of the overflow tank. By occasionally I mean no specific time interval or temperature. Just really random.
The overflow tank on it now doesn’t have any pressure control means. The cover is just a snap cap like on a windshield fluid reservoir. The reservoir has 2 1/4” tubes, 1tube vents to the atmosphere, the other goes to radiator.
Not seeing how this could pressurize the cooling system, I checked out the coolant tank and ordered a new one with a pressure cap and 3 lines. The new tank has an additional 5/8 line fitting on the bottom.
Where does this 5/8 hose hook up to the engine? Can’t find a picture anywhere.
Cooling system was just serviced last weekend and it has never overheated while we’ve owned it.
Thanks,
Andy
