Not too long ago these Mitsuboshi t-belts were thought be a good lower price aftermarket alternative to the OEM t-belt. If you have been running the Mitsuboshi belt, how has it worked out ?
If you recently bought a OEM belt is it still made by Gates Unitta - Japan ?
FWIW, I am currently running a Mitsuboshi aftermarket belt on a 99 Toy Avalon V6 . There have been no problems since the install 3 years ago, but this is a low use vehicle. They are the OE supplier for Toyota for this particular engine and also for some Subaru and Honda. This belt was part of the popular Aisin t-belt kit for these cars, and appeared to look identical to the OEM belt.
Re: Timing Belts - Anyone Running a MitsubOshi Belt?
I was gonna keep my mouth shut because I know that I’m a rookie here and a lot of you guys have helped me out with the new 92 vr4 that I recently purchased in as is condition with a 9/10 black exterior and 9/10 tan interior. But the car jumped time prior to my purchase from the original owner a month ago.
So anyway let’s go back to around February 1993 I’m a senior in High school driving my 1500 ish miles black brand new 3000gt Vr4 to Automotive HS in Brooklyn ny when I’m driving very slow in stop/Go traffic from one end of Brooklyn to the other end in morning ice cold rush hour. I never ever beat on this bone stock car keep in mind. All of a sudden the light turns green and as I’m accelerating in first gear I gear 3 very quiet backfires almost like small firecrackers (not that hollow pop that gunshots make. This was more of a pop. Almost like a glass bottle breaking without the echo). Anyway it stalls out. When I go to start it again the starter just cranked the engine with no resistance at all. As a vocational high school student majoring in Automotive technology I knew exactly what happened and right then I knew that I wasn’t gunna drive this again for a long time.
Took a walk to the pay phone and called up my mom ,even tho I was paying for the car she had to buy it for me because I was only 17 when I bought it. So she had the car picked up by the dealership. And they said the timing belt that my car was made with had a section of weak uneven stitching and a bunch of teeth broke off the belt and then shredded the outer half of the belt then it finally completely breaking apart, and after it broke it took both cylinder heads with it. Everything was covered under the warranty and they gave me a loner car till mine was ready.
So I know that a lot of y’all are pro oem timing components. And I am too. I have been the mechanic for my cousin’s vr4 for the past 24 years since his warranty expired. And I always forced him to replace his timing components with genuine Mitsubishi oem parts only especially that tensioner adjuster. I’ve worked on a lot of 6g72 variations of this engine in different cars and I’ve seen so many of those aftermarket tensioners let go less then a week after a customer had a 60k service with a mechanic using that eBay kit. The tensioner always leaks and let’s go and it’s caused more customers then not to just come back with the title to the car and say here merry Christmas. Because the heads where gone all because the mechanic cut corners to pay $50 and charge a customer $600 in 60k parts. But anyway back to my opinion. Yes I would rather re use someone’s oem tensioner and pulleys before I use aftermarket parts. But the oem Mitsubishi timing belt I lost faith in 25 years ago.
Oh btw I started my nyc career as a transit police officer in 1995 and that vr4 was stolen from a F-ing police employees and RMP police vehicles parking lot in 1996 and was never heard from again.
The car that I just purchased that jumped time had genuine oem timing components and a gates racing blue timing belt. The car still ran and the belt was tight and the only marks that were off was the crankshaft timing mark was about 5 teeth off. But I think the dealership tech dropped the upper timing cover bolt collar down into the timing compartment while inspecting the condition of the timing belt at the previous owners request during a slave cylinder replacement job and failed to own up to his mistake because the car started to run like this on his way home from that visit to the dealership.
