When do I replace my 1999 GSX timing belt

[Robotech]

Does anyone know when I should replace the timing belt on my 1999 GSX? The belt itself looks slightly worn to my eyes. The car itself only has 69k miles on it. I watched a video on how to replace the timing belt on a 6 bolt 4g63 engine and it said that the maintenance schedule was every 60k miles. I don't know when the original owner of this car replaced his timing belt.
BTW this video was good, looks like original VHS tape Mitsubishi training videos!

There is no visual way to tell. Only way to be sure is change it. My 97 had the original belt on it in 2011. Only 52k on it but a ticking time bomb at 14yrs old.

Replace belt, pulleys, tensioner, and water pump. That way you know its all done and new and not a bomb waiting to explode and ruin valves. If you have to question it or don't have proof of when it was last replaced, its always best to assume it needs done and do it.

Definitely agree with1990dsmkid... If the previous owner did not provide you with paperwork or evidence of when it was last replaced, its best to assume that it needs changing sometime soon, its also a peace of mind type of thing since these cars have their years, and most of the time its almost impossible to visually tell that the belt is worn.. better safe than sorry.

Also as stated above, once down there its best to go ahead and replace the following as well:

• Timing belt (aftermarket can be used, but do research before going this route)
• Timing belt tensioner
• Timing belt tensioner pulley
• Timing belt idler pulley
• Timing belt tensioner arm
• Water pump and gasket/o-ring

Try to only use OEM replacement components as aftermarket items have been prone to failure (especially water pumps). However you may use aftermarket timing belt after having done proper research. The Gates Racing kevlar timing belt seems to be popular from what I've read on several posts, but I personally rather go OEM.

This is the kit I purchased when I did mine. Comes with options and everything you need plus its all oem. Get this and a water pump and your good to go. I bought a gates water pump instead of paying the ridiculous price of an oem water pump. Im having no issues with it and the reviews on it were good so I gave it a shot and Im happy with it.

Aisin is the original OEM for the DSM water pump. If you buy theirs and not the Mitsu, its a lot cheaper for the same OEM pump.

Awesome, thanks! I've been buying from extremePSI lately and they get me stuff quick. I think you guys are right it should be replaced for sure.

I was wondering tho what the normal maintenance schedule is though.

I was wondering tho what the normal maintenance schedule is though.

Recommended interval for timing belt replacement is every 60,000 miles. This includes the balance shaft belt or "timing belt B". While you've got everything apart, might as well replace the water pump. I also like to replace the L shaped auto tensioner and all the pullies on a car I've just come into ownership of as well. It's more expensive for all the additional parts, but the peace of mind is worth it to me.

That video is kind of funny. Perfect TBT video! It makes the t-belt replacement look like something any old schmuck can do in his garage in an hour. It's a bit more involved though. I've always used the factory service manual as a guide along with VFAQ and been fine. Unsure of your mechanical experience but so long as you pay attention to detail and double check bolt torque and all timing marks line up, you'll be golden.

I would agree with Kreez on that. I just assume spend the few extra dollars on the parts and replace all of those parts and have the peace of mind. It's a lot cheaper than the cost of a failed timing belt part.

As a side note, where can I get a service manual for a 1999 GSX?

Check ebay. Should be able to find the books or a cd.
