How do you change a timing belt on a Mazda 626 1999 6 cylinder?

Answer 1

the easiest way to change the timing belt is to remove the grill, center section of the radiator support, and the radiator and fans. Leave the airconditioner condesor there, it would be more difficult to remove. Once all that has been removed you then have to remove the blelts, the tensioner (completely) and the crack pully. then you have access to the timing chain cover, which you then remove and there it is. A tip when replacing the belt is to also replace the water pump since you already went through the trouble. I just did all this yesterday and the water pump cost 39.99 and belt was 35.00.

Answer1. slow percausion 2. use a menual step by step 3.starting with cam pully 4.work your way in and out 5. ) AnswerNot to be rude, but if you have to ask, you need take it in.

A TB is a project for someone with a good mechanical aptitude (and most likely, a shop manual), it is not just a simple fix, like a bulb or radio, etc. If you do it wrong, you'll likely leak coolant, or worse, total the engine.

Most newer engines are 'interference engines' meaning a timing belt that breaks, slips or has some other sort of misalignment causes physical (costly) damage to the engine's internals.

Usually, it is the valves that get bent, which entails about a $750 repair (in addition to the cost of the belt repair). Worse, a piston or cylinder wall gets cracked, which usually means a new engine, that can become a $2000 expense real quick.

Dealers are expensive, usually 30% more than independent shops on a timing belt.

Find a good local independent shop and consult with them, you will likely spend about $150-$200 in parts, and another $300-$400 in labor. Not cheap, but a lot better then the alternative.

ANSWER:

Not to be a prick.. but the dude (Mark) that answered above me most likely works for a mechanic shop. I have rebuilt 4 engines and have done it all by trial and error. Ask questions and/or grab a Chilton manual. The best way to save money is to do it yourself. Just keep an eye on what you are doing and be sure to mark what you disconnect so you don't forget where anything goes. EASY AS PIE!!
