Summary: In this auto repair blog we cover the basic timing belt R&R procedure on common Mitsubishi 2.5, 3.0, 3.5 and 3.8 V-6 SOHC engines. These interference engines can sustain valve damage if the timing belt breaks. We’ve got suggestions that can help make the job of replacing the timing belt and/or water pump successful. Listed are different Chrysler and Mitsubishi models that use engines with the same basic design when it comes to water pump and timing belt replacement. Also a diagram for timing belt routing and marks for the 3.5 SOHC.
Replacement intervals can vary, Mitsubishi recommends timing belt replacement on most of the models we cover every 60,000 miles. Consider the fact that if a related component such as the water pump, idler pulleys, hydraulic tensioner, cam seals or crankshaft seal fails it can ruin any timing belt – old or new. Purchasing a timing belt kit that comes with the new idler pulleys should be considered. Also depending on the mileage, it may be a good idea to replace the hydraulic tensioner, oil seals and the water pump for extra insurance. As we stated in the summary, interference engines can be subjected to valve damage if the t-belt breaks or strips, so it’s important to take precautions to allow the new timing belt to last it’s expected service life.
