Shop around for parts, try to get at least 3 prices and use the gift of the gab to try and get trade price, going in with overalls and a liberal application of oil and muck usually does the trick. So will usualy try to do most stuff myself, armed with a bag of spanners, a haynes manual and a bit of blind ambition. I'm quite handy when it comes to automotive engineering, even if i do say so myself, in fact sometimes I actually enjoy it. Being a french diesel engine, there will be plenty of life in it yet if you look after it. Must be a reasonable business to be in, over inflating prices and the obligatory extra jobs they 'find' whilst fixing the original problem, praying on the ignorance of the general public. Its the stetson and saloon doors on the garage that ussually gives it away. The vehicle is road tested to confirm normal operation and a service sticker is affixed to the engine noting the date of belt replacement and the vehicle mileage.> i'll be expecting one of those sharp intakes of breath now, cowboy grease monkey stylee!.Upon completion of the installation, the engine crankshaft is turned by hand 720 degrees and the correct position of the timing marks on the crankshaft and the camshafts is confirmed.Installation of the new timing belt includes all of the above steps, performed in reverse, following strict guidelines to assure camshaft and crankshaft (and balancing shaft, if equipped) are in perfect alignment after tensioner has been set.If the engine cooling system thermostat is only accessible with water pump replacement, the thermostat should be replaced as well. If replacing the water pump, do so at this time, and of course drain the cooling system first.Remove timing belt tensioner and idler pulleys. Lock camshafts, as required, and note position of camshaft timing marks. Remove all accessories interfering with the removal of the timing belt covers.Once the engine is cold, set the crankshaft to top dead center with the number one piston on the compression stroke.How do mechanics replace the timing belt?Įngine designs vary, and thus the replacement procedure will vary, but broadly, the procedure is as follows: If your car has an interference engine, replacing the timing belt according to the maintenance schedule will minimize the chance that a belt failure will cause engine damage. These engine designs are referred to as interference engines. ![]() ![]() On some engines, if the timing belt has jumped, the pistons and valves can collide and there will be noise and damage. Should the belt jump, the engine will run poorly and perhaps not at all. After many tens of thousands of miles, the teeth can wear or break, or the belt can stretch, thus causing the belt to jump position on the crankshaft or camshaft gears. ![]() The molded, reinforced teeth on the timing belt engage gears on the crankshaft and camshafts. Occasionally, timing belts can break, or skip, while the engine is running.
