Hi, do I need to change the timing belt on c 240, year 2002

not normally most mercs have a chain timing belt so dont need doing its only need replacing if its worn which in most cases you can here a rattle from the engine dont let any one tell you they need changing every so many thousand miles as this is rubbish mine has 176000 miles and still has originall chain hope this helps

Hi, this really depends on its service history.

The following are the recommended service intervals on the Merc S500:

Note: operate A/C at least once per week, to maintain lubrication.

Underhood & Undervehicle

Every 3,000 miles - Replace engine oil & oil filter. Clean battery terminals. Adjust drive belt. Check power steering fluid. Check steering & CV BOOTS for wear and replace if necessary. Lubricate front end suspension.

Every 6,000 miles - Check transmission fluid condition and level. Check brake pads and caliper components - replace if necessary. Lubricate driveshaft U-joints. Rotate tires. Lubricate wiper arm linkage and pivots.

Every 12,000 miles - Adjust engine valve clearance. Replace distributor cap & rotor. Drain and replace engine Coolant. Replace Air Filter element. Replace Fuel Filter. Replace wiper blades.

Every 24,000 miles - Replace Drive Belt. Replace A/C Compressor Drive Belt. ** Change auto transmission fluid & trans filter (this is critical and must be adhered to) - preferrably do a trans flush at same time. Replace drive AXLE fluid.

Every 36,000 miles - Replace HT leads.

Every 2 years - Replace brake fluid (also clutch fluid if applicable). Replace power steering fluid.


** If you intend to keep this vehicle long term, then consider changing the trans fluid & filter every 20,000 miles. This is the secret to automatic transmission longevity.

Your car does not have a timing belt,it is chain driven.
Only needs attention if it fails in any way
Should last life of car

Your best longevity check is to set up and maintain a consistent oil and filter replacement schedule...Depending on your planned driving habits...your owners manual should recommend you change these every 5000-7500 miles or every 3 months whichever occurs first. Oil products have inproved for many years. The synthetic oil blends are the best for performance and mileage...most exceed your Cadillac specs...Mobil 1, and Castrol full synthetic are by preferences...No special tune-up or other maintenance should be needed at this time...watch for serpentine belt...100,000 miles...plugs and plug wires...100,000 miles...suspension parts vary between 75K to 100K before replacement...Hope this helps.

2002 ISUZU AXIOM MANUAL SAYS
CHANGE THE TIMING BELT AT 100,000 MI FOR NORMAL DRIVING CONDITIONS AND 75,000 MI FOR SEVERE DRIVING CONDITIONS

At your own risk. Timing belts are only rated for 60000miles but have seen them go much longer. you do roughly 7500miles a year, i would be of the opinion that u should change the belt due to age and miles at 65000.

60,000 miles is the typical recommended interval for timing belt replacement. The belt can become worn and skip a tooth or even break. In that event, the pistons can collide with the valves and cause a considerable (and expensive) amount of damage. Changing the timing belt at recommended intervals is good insurance to protect against valvetrain and piston damage due to belt failure.

its to my knowledge that vw have had problems with the timing belt going between 65000 to 75000miles, and recomend checking it every 4 years so if it hasnt been done yet and u have more than 65000 miles on it i would recomend getting it checked

between 65000 and 100000 miles is the service interval

if you dont know or are unsure change it for your own piece of mind
