I have been having loss of coolant issues in the 87 3.0L wagon for the past 6-9 months. After driving 500 miles or so, the car goes from the cold fill line on the container down to empty.
The car has all new heater hoses all over (replaced all of them), radiator, heater core, thermostat, timing cover gasket, and a new aftermarket (not a reman aftermarket) water pump.
So last time it was humid outside and at night, I got my flashlight out and looked around. I found that I have 3 or 4 leaks going on.
1) Somewhere between the water pump and the timing cover is pooling coolant right under the U hose that goes between the pump outlet and one of the metal lines near the passenger strut tower
2) Two places on the hard metal lines that run behind the UIM
(1 pretty bad, 1 minor) are leaking out coolant
I may just check bolt tightness on the water pump and make sure hoses are tight. But for the metal coolant lines that have rusted through are leaking what do I do?
There's a 88 3.0L Sable in a yard about 90 miles away that has the replacement from Ford, as it has a manufacture tag from the early 2000s w/the Ford part number. Is that worth getting or is there some kind of replacement I can make?
