Timing belts and water pumps

Lots of people hear “timing belt change” or “cam belt change” and they stick their head in the sand and ignore it. They live by the philosophy that if it isn't broken don't fix it. Or they will look at the belt and say “it's fine, it still looks like new”. When they finally decide to go ahead and get it changed, they will decline the offer of a water pump because it's slightly more money and “my old one is still ok”.

Here at our Letchworth based garage, through lots and lots of experience (25 years worth to be exact), we can tell you the extreme importance of getting a timing belt AND WATER PUMP changed at the recommended intervals. We have put together some helpful tips and advice.

-A Timing belt is under an enormous amount of stress the entire time the engine is running
-Due to their laminated construction the belt breaks down internally long before it will begin to break down externally (making a visual inspection almost useless)
-When a Timing belt breaks it can cause severe internal engine damage!!!
-If a Timing belt breaks when an engine is at 2500 RPM, (average driving revs) the pistons could potentially hit the valves 22 times within a second
-The average cost of repairing engine damage caused by a broken cam belt is around 4 times more than the cost of the cam belt and water pump replacement.
-A water pump bearing is also under enormous amounts of stress.
-If they are not replaced they can leak coolant that can cause the engine to overheat
-When they break they tend to seize, which will often damage the cam belt and cause it to break

Not changing the water pump when a timing belt is done can cause just as much damage as not changing the cam belt at all. We always recommend to our Letchworth based customers to change the water pump at the same time. It only adds a small amount of a labour. But you can be assured that you are not getting a costly repair coming your way.

If you have any questions at all about timing belt or water pump replacement, then do not hesitate to contact us at our Letchworth based garage. You can contact us at Autolube on 01462 481342 or email you questions to ask@autolube.net
