The only way to get an accurate idea is for us to prepare an estimate for you. The technician fee is normally fairly constant - it is the cost of the parts that can vary dramatically. The cost of changing a Cam belt correctly is between $450 and $1400 with most coming in between $600 and $800. As the technician fee is around the $350 mark it usually makes good sense to change it at the same. If it were to fail or start to leak, the amount of technician time to replace it is identical to that used to replace the cam belt. In the case of engines that have the water pump driven by the Cam belt (most of them) the water pump is located behind the Cam belt. Be very cautious of a anyone who claims they can change your cam belt for a very low price – they will more than likely do exactly that and change the belt only.

On cars with spring tensioners, I prefer to install the spring tensioner as Im routing the timing belt. If this happens a brand new belt can fail in just a few kilometres. Install the cam belt tensioning roller if removed. If these are not changed at the same time, the bearing in them can collapse and cause them to stop turning. In addition to the belt there are tensioners and other components that the belt runs over. Pictured opposite is a belt that came out of a car that had only done 70 000km, but was 9 years old.ħ0 000km 9 years old Broken Timing Belt (Perished)īeing made of rubber and nylon, the belt gets old and weakened by both use and time and may break if it is not changed. In practice they tend to last about 10 years, but this is at the owners risk. The Manufactures all put a 5 year maximum Time interval on the life of a Timing belt. On most cars the manufacturers recommend that the belt is changed at 100 000km intervals, but some are as low as 60 000km and the highest we have seen is 150 000km. 1 These valves allow the engine to inhale air (or an air/fuel mixture) and exhale the exhaust gasses. The crankshaft drives the camshaft (via a timing belt, timing chain or pushrods), which in turn actuates the intake and exhaust valves. Replacing it also demands understanding how it works. Design In most piston engines, the camshaft (s) are mechanically connected to the crankshaft. Some people are lucky and no damage has occurred. Timing belt replacement requires a minimum of know-how in general car mechanics. This can be repaired but is very expensive and in most cases where damage has been done it is cheaper to replace the whole engine with a second hand one. This means that some of the valves in the top of the cylinder will remain open (Down) and the piston comes up and bends them (and in some cases makes a hole in the top of the piston). When a cam belt breaks the crank shaft continues to turn, but the Cam Shaft stops. The belt is made from a very special reinforced rubber and has teeth on it so that the timing is always kept correct.

It can also drive the water pump and oil pump on many engines. The belt is located at the front of the engine and is used to drive the camshaft in time with the crankshaft. The Cam belt is also known as the timing belt.
