Are all Pajeros prone to overheating? Hello Paul, I would like to procure a Mitsubishi Pajero V93W, 3.0L, Petrol. It is, however, alleged that all Mitsubishi engines overheat despite the model and age. From your experience, how true is this? Vincent Hello Vincent, treat as idle talk any allegation that Mitsubishi Pajero engines across all models and ages have an engine overheating problem. Engine overheating is a problem that can happen to any vehicle engine, regardless of the model or age. There are issues that cause overheating such as poor cooling system maintenance (coolant service to prevent damage due to corrosion and heat buildup) as well as failure to repair broken down cooling system components such as electric fans, leaking radiator or hoses, water pump, thermostat and fan switch.
