1990 f150 302 using up coolant
so the truck has started using up the coolant.
no steam from exhaust, no drips and runs perfectly.
so need this truck right now so i have been filling up the expansion tank with straight water .
goes about 20 miles half gone.
so then looped the heater hose and put in my spare known to be good radiator.
still gobbling up the coolant.
no idea where it’s going ….yet
then I threw in 3 of these …did absolutely zero….ha ha
have to decide what next.
