How to Clean a Toyota Land Cruiser EGR Valve

A Toyota Land Cruiser's EGR valve can become clogged over time, and will need to be cleaned. The EGR valve, also known as the exhaust gas recirculation valve, is a crucial part of a Toyota's engine air intake. The EGR valve directs the engine's exhaust into the manifold, which cools down the engine air; the process prevents the vehicle from overheating. Cleaning the EGR valve is very important to ensure that your engine works efficiently.
