For expert Timing Belt replacement in Leeds



Timing/Cam Belt Due?


Replacement from as little as £60 inc. parts






Certain engines with overhead camshafts have timing belts that have a limited life span. Car makers use these belts instead of more durable chains because chains are noisier and cost more to manufacture.  Your vehicle owner's manual will recommend at what mileage/ time the timing belt must be replaced.  These intervals range from every 40,000 miles to every 105,000 miles and from 4 to 10 years.


Here at New Rodley Motors our technicians we will only fit belts with manufacturers specification e.g Gates, not inferior belts which cannot guarentee to live up to manufacturers expectations.


If you have any queries regarding your Timing/ Cam Belt, even if your not sure when your belt is due, do not hesitate to contact one of our experienced technicians on 0113 257 7770 who will be happy to help.



What the Timing/ Cam Belt does:


The job of the Timing Belt is to turn the camshaft(s) at exactly 1/2 the speed of the crankshaft while maintaining a precise alignment.  This means that the crankshaft will make two revolutions for every revolution of the camshaft.  Engines will have at least one camshaft or as many as four camshafts in some of the V-type engines.  The camshaft causes the intake and exhaust valves to open and close in time with the pistons which move up and down in the cylinders.  The valves must open and close at exactly the right time in relationship to the piston movement in order for the engine to run properly.


There are two types of engines that use timing belts.  They are described as: "Interference Engines" and "Non-interference Engines"  The difference lies in the proximity between the valves and the pistons.  On an interference engine, if the timing belt slips even one notch, the piston can crash into an open valve causing serious engine damage by bending valves and breaking pistons.  Non-interference engines will usually not self destruct, but in either case if the belt fails, the engine will immediately shut down leaving you stranded.


Timing belts fail without warning and on some vehicles, are almost as hard to check as they are to change.  In most cases, your only protection is to change the belt at the recommended intervals. Timing belt replacement is not a cheap job but it is far less costly than the alternative.


Some technicians may recommend that you replace the water pump during a timing belt job even if there is nothing wrong with it.  This is because 90% of the labour to change the water pump has already been done with the timing belt job and some technicians consider it good insurance to replace the pump at this time.  We feel that some water pumps can last the life of the car but many do fail and will cost big money to replace at a later date.  So ask one of our Technicians at New Rodley Motors, what the water pump is like on your model car and look at how long you plan to keep the car. This way, at least you will be making an informed decision on what to do.
