My radiator (89 GQ 4.2 TD) was weeping when hot and under pressure (Electrolysis?)
It was repaired 2 yrs ago but I have now given up and put an Al alloy unit in as recommended by my 4x4 mechanic / specialist 4wd guy. He uses the same type in his rigs so went that way too.
Looking forward to another 27yrs of trouble free motoring.
Cheers
Chimo
So you had the whole system cleaned and flushed to a high standard before fitting the alloy job?
