Thread: Isuzu Bighorn or something else?

Depending on model/year. But if diesel, keep it cool, get radiator flushed and track down a lower temp thermostat, there are other mods you can do to help with temperature but rad and thermo are usually enough. If auto fit a remote transmission oil cooler.(petrol or diesel). Petrol V6 can be thirsty, especially the earlier ones. 2.7 petrol 4 cylinder are good engines.
