It's A Good Idea To Replace Your Water Pump While Doing The Timing Belt.

That Saves The Additional Labor For Having To Do It Seperately.

What The Timing Belt Does:

A timing belt, timing chain or cam belt is a part of an internal combustion engine that controls the timing of the engine's valves. Some engines use timing gears others use timing chains. The timing belt is a flat belt with internal teeth that are used for maintaining a specific drive ratio.

In the internal combustion engine application, the timing belt connects the crankshaft to the camshaft(s) which in turn controls the opening and closing of the engine's valves. A four-stroke engine requires that the valves open and close once every other turn of the crankshaft. The timing belt is specifically designed with custom teeth for a particular engine to synchronize the camshaft with the crankshaft. In some engine designs, the timing belt may also be used to drive other engine components such as the water pump and oil pump.

A gearing system can be used to connect the crankshaft to the camshaft at the correct timing. However gears and shafts constrain the relative location of the crankshaft and camshafts. A belt or chain allows much more flexibility in the relative locations of the crankshaft and camshafts. Furthermore, belts are cheaper than a gearing system. While chains may be more robust, rubber belts are quieter.

Timing belts are typically inaccessible and difficult to inspect. Replacement at specific intervals is recommended by the manufacturer. The manufacturer may also recommend the replacement of other parts, such as the water pump, when the timing belt is replaced because the additional cost to replace the water pump is negligible compared to the cost of accessing the timing belt. Failure of the timing belt will leave the engine non-functional. Depending on the design of the engine, the piston and valve paths may "interfere" with one another and incorrect timing in their movements may result in the piston and valves colliding. (Such designs are also called "interference head" or "interference engines". Conversely, non-interfering engines are called "free-wheeling" or "non-interference" engines.)

In interference designs, regular service is especially important as incorrect timing may result in the pistons and valves colliding and causing extensive engine damage and therefore costly repairs. The piston will likely bend the valves or if a piece of valve or piston is broken off within the cylinder, the broken piece will cause severe damage within the cylinder, often also affecting the crankshaft. In some newer engines, timing belts are designed to last the effective life of the engine. When a timing belt is replaced, care must be taken to ensure that the valve and piston movements are correctly synchronized.

A timing belt is typically rubber with high-tensile fibers (e.g. fiberglass or Kevlar) running the length of the belt. Rubber degrades with higher temperatures and with contact with motor oil and antifreeze. Thus the life expectancy of a timing belt is lowered in hot or leaky engines. Newer or more expensive belts are made of temperature resistant materials such as "highly-saturated nit-rile. Older belts have trapezoid shaped teeth. Newer manufacturing techniques allow for curved teeth that are quieter and last longer.


BRAKE REPAIR & SYMPTOMS

Brake pads and brake rotors are wear items and should be inspected regularly and replaced when approximately 1/8" of friction material is left on the brake pad backing plate. Brake rotors should be replaced when at or near the discard thickness engraved on the brake rotor.

CLUTCH REPAIR & SYMPTOMS

A complete clutch repair is diagnosing the cause of the problem and replacing all worn or damaged clutch components. Clutch component parts do wear and some self adjust to compensate for normal wear in clutch disc friction material.

TRANSMISSION REPAIR, SERVICE & SYMPTOMS

Neglect and overheating causes 90% of all transmission & transaxle failures per industry feedback and most of them are due to worn out transmission fluid. Regular transmission service can help avoid major transmission repairs

DIFFERENTIAL REPAIR, SERVICE

High operating temperatures reduce the gear lube's ability to lubricate, which can lead to axle and bearing failure leading to major differential rpairs. Differential service includes draining &fillin with new gear lube. to avoid expensive repairs. Most manufacturers recommend differential service every 30.000 miles.

CLUTCH SPECIALS & REPAIR

Escondido Ca Clutch Repair and Service. The clutch repair specials include all four pieces of the clutch, resurfacing of the flywheel and labor. Service the clutch on a regular basis to avoid clutch repairs.

MAINTENANCE REPAIR & SERVICE

Maintenance Repair & Service. 30K-60K-90K-120K Maintenance repair & service are typical and are not specific to any vehicle. Always refer to the vehicle owners manual.
