Happy new year all fellow Patrolers, Guys iv got an obvious question, my deisel gq 4.2 runs 12pound boost with a factory radiator GU top mount cooler and ED falcon twin thermo fans! The thermo's always work a treat and i have never been anle to get her past halfway on the heat guage when in the scrub and city, however i towed my 1400kg caravan at xmas and she heated up something shocking, regardless of up or down hill at 100 she sat just off hot at 110 she would hit the H line so id have to back off, i was a bit slack before xmas and was only running water in the radiator which i know wouldnt help but i dont think coolant would have made a massive difference! Should i look at updating to a 3core alaminium rad or something as i have big plans with towing the van around aus and so on and dont want the damn thin heating up, especially cos power wise it toes fine! Anyone been here before? Cheers guys. Gardy.
