Does your Mitsubishi L300 make a strange noise? Need wheel alignment specs?

Alternator Belts replacement

Post by philmeup1 » Wed May 15, 2019 9:13 am

Hello folks,

I gave that all to familiar squeak coming from the belts of my '93 L300. I've ordered a new set of genuine Mitsubishi belts as well as the power steering belt from amayama. My plan was to have a friend who teaches Auto Mechanics do the job with some of his students. The problem is that we're getting close to the end of the school year, and they're very busy with other (not nearly as cool) vehicles, 8-)

So I'm thinking maybe I can do this job myself. I have access to a great shop with a host. The only thing I'm missing is the mechanical ability. Well, I do have some skills in the automotive department, and hopefully enough to do this job :o

So I've been researching older posts on here, and it looks as though removing the drivers seat and access cover alingveith the fan shroud is the best way to tackle this job. If anyone has any further advice on the best way to do this job, I'm all ears. I've looked at tojo's awesome thread on head removal, but its much more removal of parts necessary than just replacing the alternator & power steering belts.

Thanks in advance ,

Phil

I too would be interested in having some direction with this. Photos would be appreciated.

You're onto it with removing the driver's seat and fan cover. You'll also want to remove the fan itself as well. Then mark the location of the fastener on the a/c tensioner, remove it, and loosen the tension to be able to take off the a/c belt.
To remove the power steering belt just crack loose the 12mm bolts on the pump to be able to pivot the pulley, then slide the belt off.

That'll give you access to the alternator belts. To remove them there is the bottom bolt to loosen so the alternator can pivot, and then you can start loosening the tensioner on top till you have enough slack to remove them. Once they're off then put the new ones on and tighten the tensioner to 10mm deflection (i think), and then tighten/replace/ retourqe all the other bolts and belts.
Good luck!

Thanks joebillhill. This bit of info helps for sure. I dont think I even need to worry about the A/C belt as I had to cut it off last fall due to the compressor pulley seizing. Hahaha

I think I might be able to do this. Wish me luck :shock:

Thanks again for the help

For replacing the timing belts, I'd print out the relevant sections of the workshop manual (dis/reassembly steps, torque settings) and mark off each step as you complete it. Refer to Tojo's thread for guidance where the workshop manual is too vague.
Take photos as you go.
Have a bunch of jars or baggies to put nuts and bolts in, and a sharpie to mark the baggies with the name of the assembly the bolts came from.
Rags, cleaner spray, and a wire brush for getting all the oil and crap off stuff as you remove it. Disassembly is messy, but you want reassembly to be clean.

Before starting the engine, turn it over by hand a few times (19mm socket on the crank pulley bolt) and re-check your timing marks. This will save your engine if your timing is out by a tooth or two.

Will your friend be able to help if it all goes wrong?

Tojo's thread is pretty great (http://www.delica.ca/forum/viewtopic.php?f=6&t=16587) but it does have more steps than are required for just a belt change. When he starts removing the glow plug bus bar, skip ahead to crank pulley removal. Then, when he's talking about lifting points, skip ahead to the water pump.
Nothing says "poor workmanship" more than wrinkles in the duct tape.

Hey Growler,

I'm only going to change out my alternator and power steering belts this time around as I believe I can do this job myself. I'm at 74K since the last time I had my timing belts changed, so I'm reluctantly leaving this job until next year. I have the link you shared with the relevant parts of the workshop manual and of course tojo's awesome post as well. But this job is well beyond my capabilities and I think I'll have to pay a garage to do it. I'll be sharing those links with whomever ends up doing the timing belts for me. And perhaps if I get lucky, my friend who teaches auto will have the time to do this job with his students next year 8-)
