1998 Chrysler Town Country 3.8L Does it Have Timing Belt Or Chain

this engine have a timing chain

It was the older Town and countries that had a chain. Yours has a timing belt.

The 3.3 litre engine has a timing chain. No recommended change interval. Around 90k i would consider replacement because they will wear and stretch.

Contact the dealer or read the owner's manual.

it has a chain

3.0 liter timing belt , I think, are recommended at 60,000 miles but you could easily get 100,000 miles out of them. They are a non interference engine so if it does break it will cause no other damage besides maybe ruining a timing belt cover. Usually the water pump will fail before the timing belt does.

Are you sure you have a belt, not a metal chain? To my knowledge all the Chrysler V6 engines use a timing chain, which should last the life of the motor. Ask your local auto parts store, they can tell you for sure.
(Don't confuse the timing belt/chain with the serpentine drive belt which runs the air conditioner, water pump, power steering pump, etc. The serpentine belt is always rubber and is visible at the front of the engine (your left as you face the car with the hood open). This should be inspected once a year beginning at 5 years or 60,000 miles, and replaced once it starts showing cracks or wear. If you have never replaced yours, you are due for it now. I just replaced mine on my 2005 T&C with 63,000 miles.)

If you do have a rubber timing belt, I would replace it every 6 years or 60,000 miles (whichever is first) unless the owner's manual calls for a different interval.
Many engines today have "negative valve clearance", which means if the timing belt breaks, the piston will run into the valve, possibly bending the valves. This means a full overhaul of the motor, which is *much* more expensive than replacing the belt.

A metal timing chain is internal to the engine and lubricated by engine oil, and will not break like a rubber belt can. It will last the life of the motor (150,000 miles or more).

Timing belt maintenance is extremely important! All Neon models utilize an interference-type, non-free-wheeling engine. If the timing belt breaks, the valves in the cylinder head may strike the pistons, causing potentially serious (also time-consuming and expensive) engine damage. The recommended replacement interval for the timing belt is 102,000 miles (163,000km), or sooner.

the timing chanin is behind the timing chain cover on the passenger side of the engine. u must remove the crank pulley to remove the cover.

no you do not have to remove the engine to service the timing chain

Normally with a timing belt its recommended that you change the belt at 60,000 mile. If its a chain at 100,00 miles.
