Timing Belt 101
What is a Timing Belt?
A timing belt is a part of an internal combustion engine that controls the timing of the engine's valves. In the internal combustion engine application, the timing belt connects the crankshaft to the camshaft(s), which in turn controls the opening and closing of the engine's valves. The timing belt does this. It has custom teeth to turn the camshaft(s) synchronized with the crankshaft and is specifically designed for a particular engine. In some engine designs, the timing belt may also be used to drive other engine components such as the water pump and oil pump. Some indicators that the timing belt made need to be replaced includes: reduced engine poor and poor economy, intermittent back-fire, as well as a rattling noise from the front of the engine.
Why is it important to change your timing belt?
Timing belts are typically inaccessible and difficult to inspect. Engine manufacturers recommend replacement at specific intervals. The manufacturer may also recommend the replacement of other parts, such as the water pump, when the timing belt is replaced because of the additional cost to replace the water pump is negligible compared to the cost of accessing the timing belt. For engines whose valves extend into the path of the piston, failure of the timing belt (or timing chain) invariably results in costly and, in some cases, irreparable damage, as some vales will be held open when they should not be and thus will be struck by the pistons.
What do we recommend?
At McKenney-Salinas Honda we recommend timing belt replacement intervals at 90,000 miles or six years or 105,000 miles or seven years dependent upon the model and year of your vehicle.
Timing Belt Replacement Includes:
- Replace Timing belt
- Replace Balance shaft belt (if applicable)
- Replace all drive belts
- Replace water pump and coolant
- Inspect timing belt tensioner
