Hello all, I have recently upgraded my 94 diesel troopy 1HZ to a 1HZ upgraded to 1HD with an after market Denco turbo not intercooled. New radiator same size as original, fan checked by Toyota and new 3 inch exhaust, clutch. In short we bought a caravan and GVM is 3 tonne but more likely 2.5 when we go away. The troopy has heaps of power but when we hit a hill or a long slow rise the turbo heats up to 500+ deg and the radiator comes up to the boil. Things get touchy if the hill is to long and the troopy just wont cool down until im rolling down the other side and it comes back to norm pretty quick, drives normal with no overheating all-day when not towing. Have had the timing checked and now scratching with nearly $20,000 spent on motor and turbo with all the other bits and pieces. Should I put a intercooler on turbo or just put a huge radiator in it. have been quoted $1000 for this radiator that is one extra core but smaller tubes. Any other suggestions to keep it cool would be appreciated. Tows at 90klms/hr alright till you hit a rise, but wont tow at 100klms/hr the temp starts to creep up.
Thanks in advance
