so i know there are plenty of threads discussing timing belts..i felt the need to create this thread because i have a 2001 GS300 with now 25k miles. I acquired the car about 18 months ago, i've replaced the serpentine belt among other things but nothing crazy. The schedule states 90k or 6 years..in my case the years..twice rolled over. I have 0 idea if the belt has been replaced before (or water pump while at it) so im reaching out to you fellow 2nd gen GS brothers. If i do opt to replace them both, what else should I get done while I'm at it (seals, fluid changes etc) Any help of course would be greatly appreciated. I'm taking a trip up to Orlando in 2.5 weeks so that is what prompted me to consider this maintenance route.

also the car hasn't given me any grief aside from what i read is a common transmission catch from 1st to 2nd gear..as in sometimes it'll hesitate going from 1st to 2nd..i was concerned about that but read a lot of people having this issue and at this time it hasn't done it in a month (so i know if i took it in duplicating may not even happen)

 

Ive seen guys replace the OG timing belts at almost 150k miles and they still look new so most likely you'll be good but if you want to be on the extra extra safe side you can knock the TB and WP out. If you do decide to buy them, register on Sewell Lexus parts and you'll get a Club Lexus discount.

 

You should do the timing belt and water pump to give you a piece of mind. Or you can have your mechanic check it for you to see if the belt shows any cracks or signs of wear.

 

I wouldnt do it, the belts still look great at 120k you have almost 90k less mileage you will be fine do it at 90k

 

good to know..yea it's the time that has me concerned..12 years on the same belt it makes you wonder..speaking of wonder, does the code get emailed to me after signing up?

 

Piece of mind says to change it.

 

so i took off the engine cover and belt cover, lo and behold belt looks like it will require replacement. yahtzee..now its a matter of finding prices for the labor

Get a timing belt kit from Rockauto, cheaper than Sewell by a decent amount IIRC, and it`s the same ****.

RA gives you an AISIN box, Sewell gives you a Toyota box - that`s the difference

 

TB, WP, Idler, thermostat, crank seal, cam seals, consider VVTI gear, hoses, serpentine belt, pcv and check tensioner

 

This is a legit list. I did most of this last Sunday including the rebuilding of the VVTi cam gear since mine was leaking all over the place. I also did my plugs and valve cover gaskets when I realized that they were in desperate need. As far as your water pump, you may not have the mileage but do it anyway.

 

yea i plan on getting the waterpump/timing kit..told my mechanic when he checks it out to lmk if anything else needs to be done while at it. I just need it all done by this coming friday before making a 300 mile trip..i've done the serpentine already myself as well about a year ago

 

I'm in the more "peace of mind" camp. I did my 2002 GS300 timing belt right when I bought the car with 84k. Wanted to just get it done right away so I didn't have to worry about it. The water pump was in great condition, so I passed on replacing it. Car runs great and I'm taking it on its first long trip next weekend.

 

yea 84k miles i wouldn't hesitate to replace, but at 26k miles i was like ehh idkk but after noticing how easy it was to at least get a view of the belt i did just that and im glad i did because belt definitely needs replacement..got the timing belt kit from sewell..just to get it all done why not..i do plan on keeping this car for quite some time so i want to keep it on point.

 

Absolutely. If you plan to keep the car along time, may as well just get it done for peace of mind. I believe it is an every 90k service or so. With your low miles, you should have many years of trouble free service.

 

Wow good to know..thank you. I already purchased the timing belt kit from sewell lexus but I know not all of those parts aren't included. Ill look into sourcing them for my tech to plug in. I appreciate you looking for the kit for me id still like to check out what I still need
