If you simply want to check the timing belt condition, then remove the plastic cover and visually inspect it. If you have the 5 sfe engine, the timing belt cover is a 2 piece assembly, upper and lower. if you have the 7 afe or 4 afe engine the timing cover is 3 pieces and to inspect the top of the timing belt you must remove the 4 nuts holding the valve cover down and the 2 bolts holding the wire loom. remove the whole valve cover. to inspect timing belt condition.

hi, dear friend, timing belts should be changed every 50,000 to 75,000 miles, depending on driving conditions. For example, vehicles driven under extreme conditions, such as in excessively hot or humid weather, dusty environments, or racing or emergency vehicle operations. On 2004 Chrysler Serbing to change the timing belt at 90,000.

On the 1.6L engine:
The timing belt should be replaced at 90,000 miles.
The drive belt should be inspected for wear or cracking every 30,000 miles. However I recommend that the drive belt be visually inspected every time the oil change is performed. It only takes a second to look at it and it keeps you aware of the belts condition on a more regular basis. This is important because there are certain conditions that can accelerate a belt's deterioration.

1994 2.2 liter 4 cylinder is a timing belt, it should be changed every 90,000 miles under moderate driving conditions, under severe driving conditions (stop and go traffic, etc.) it should be changed every 60,000 miles

You would have to proceed like you were going to change the belt until you could see it to inspect it. Here is a link to instructions on inspecting and replacing it.

your timing belt needs to be replaced every 90,000 miles on the older cars they are to be replaced at every 60,000 miles. but if it was me i would do every 60k just because breaking a timing belt can cost you a motor and for your camery that can cost up to 2000 for a rebuilt motor.

They are to be inspected at

80,000
90,000
100,000
110,000
120,000

Depending on the condition of the belt it is to be changed at anytime during these inspections. There is no finite figure set by Volkswagen for belt replacement. Typically these last about 100,000 - 110,000 miles in moderate driving conditions.

Always change the tensioner at the same time as the belt. A bad or marginal tensioner will destroy a new belt.

It could only if it was disassembled and reassembled improperly. Parts of the air conditioning system would have to be removed to get to the timing belt. Hope this helps.

Your serpentine belt and timing belt are not the same thing. If your serpentine belt breaks, you will lose your alternator, your cooling system, air conditioning, and your power steering. In turn, it will leave you stranded in a very short period of time.
