Komatsu Charge Air Coolers

Your charge air cooler’s purpose is to cool the compressed charge of air coming from the turbo charger on a diesel engine prior to entering the combustion chamber.  If this charge is not cooled to a sufficient level, the engine will not operate efficiently. This is why it is so important to maintain your charger air cooler. We can help you to maintain your charger air cooler, sometimes you may not even notice there is an issue since you cannot see the leak occurring. Some signs to watch for are loss of engine power, increased fuel consumption, exhaust manifold failure, turbocharger failure and increased particulate levels in emissions.
