Dear all AOA. I have some questions for the experts here. I bought a 1994 Prado from a guy in Peshawar who got it off an auction from ANF. As the rebuild started I went on changing everything until finally in 2015 I got a 1kzte from torkham. The engine seems fine otherwise as there is no blow, no smoke from exhaust, very responsive and quick start etc but there is one issue it starts to raise the temperature gauge once the speed crosses over 100kph on the motorway. Otherwise on idle with the a.c on in mid summer no overheating. I changed the radiator and got a nice one but still no change. I locked the fan clutch and still no change. I've seen on the internet that adding an intercooler plus a separate cooler for the transmission oil, a bigger 3" exhaust dump pipe, blocking the EGR and replacing the stock thermostat with a 76 degree one will help. Will these modifications help or is there something I'm missing here.
