If the timing belt tensioner goes bad will it make a knocking sound on a 2002 Mitsubishi Montero Sport

it will be leaking oil onto the belt
it should be changed with every belt change along with all seals and idler pulleys
when in doubt ot oil residue in the housing, change it out

an aftermarket sensor can cause this-electrical generics can hav this issue--but the hardware that it is set upon cud be bad-may need a inspection by a pro---usually when a belt is replaced-the tensioners and guides etc are also done--chec out procedure in a chilton repair volume at ur library

take center nut loose from the tensioner and there is a bolt to unscrew that loosens the pulley

the tensioner keeps the tension, change it and your problem should be solved

make sure your time is right

I have a 98 Montero Sport, whenever my belt sqeaks I check the tension and usually thats the problem. Tighten them accordingly and it should solve it. As for the timing belt, mine is a belt not chain. First time I had it changed was at 100,000 miles and the dealrship said I was cutting it close ><

if it is anything like my 98 montero sport 3.0 all you need is a socket set, the tensioner should be close to the pulley near the alternator

Hi Barikinas,
I would suggest you check the knock sensor and the egr operation as the knock sensor should send information to the computer to correct the ignition timing and the egr malfunction will prevent the temperature of the combustion chamber to lower thus producing more oxides and the temperature goes higher.
