Gday everyone iv got a 90 gq td42 aftermarket turbo fitted no intercooler. Along the flats the guage will sit between a quarter and a half. But give it a decent jump up and not towing anything the gauge goes up to 3/4 thats to hot for me. Also certain hills around here she gets to 3/4 whilst iv got no weight on at all. The radator is 12 months old, cap is good , thermostat is new. Before fitting the turbo i had no issues at all. Ive been told i need a bigger radator. Does anybody have any advice ?
