Question: My water pump went out and it costs much more to replace than ones I've had replaced in the past. My Parker technician said it's because of where it's located. Why is that?
As your engine runs, the intake valves need to open up to allow air into the engine. They remain closed while the air and fuel is compressed and ignited, powering the piston. Then the exhaust valves open to release the exhaust. This all has to be timed very precisely. It is the job of the timing belt or timing chain to make sure all of this is synced up properly.
A recent report stated that over 80% of the vehicles on the road have one or more service item or repair that's needed but hasn't been taken care of. Now that's a lot of undone service. That translates into something over 160 million vehicles in the US alone. Some of the neglected items are minor. Others are serious safety concerns.
