At what milliage you should replacement the timing belt Montero sport 1998?
Depends on how hard the vehicle has been worked, but Mitsubishi service manual says the Timing Belt should be changed at 100,000 miles.
The 2000 Mitsubishi Montero 3.5L is listed as an "Interference Engine" under timing belts in the www.RockAuto.com auto parts catalog. This means the valves or other major engine parts will be damaged if the timing belt breaks while the engine is running. So replace it as part of scheduled maintenance. Many manufacturers recommend changing the timing belt every 60K miles. I do not know if Mitsubishi recommends different mileage intervals.
Although I am not a certified mechanic....hell or even a mechanic , I would say no unless the timing chain is in the way of the gasket replacement, you should be able to on most motors replace header gaskets without the removal of the timing chain.

It should not need replacement unless you are having a problem that can be attributed to the timing (there is no preventive maintenance replacement interval).

Otherwise they are good indefinately, that is the advantage of a chain rather than a belt ANOTHER VIEW: The manufacturers recommendation for the timing belt replacement is at 105,000 miles.
A timing chain is not the same as a timing belt. Timing chains do not generally need replacement unless you are rebuilding the engine. While a timing belt is simply a ribbed, flat fanbelt that wears and can become weakened with age, a timing chain is oiled constantly and should be expected to last the life of the engine. Like other internal engine components, a timing belt is affected by the condition and quality of…
