Hi all,

I'm looking to replace timing belt next week. looking for OEM parts. would I need anything i addition to the below?

I would do Thermostat, drive belt, upper and lower radiator hoses and crank seal. You will need a couple gallons of the pink 50/50 long life coolant too.

thank you, ill look into the additional parts you mentioned

I bought kit inc pump from Amazon, then extra camshaft/crankshaft seals but I don't think I need them. I also bought thermostat/seals and drive belt, yet I only changed drive belt (although hte crack is normal), because I'm unable to took off the big bolt and timing belt is ok (98K miles) and I though it would last extra 20K at least.
If you are successful pls do me a favor on how to remove the bolt and which brand of tools you use. I see normal breaker bar is too flexible with cheater pipe.
you do need coolant and you might want to flush ATF as well. For radiator hoses they did becomes harder and had better to be replaced.

I'm actually bringing the parts to a mechanic to change and only wanted to pay for labor from the shop.

If your vvt-i pulley is leaking oil, it'll be a good time to replace that while the timing belt is off.

I would also do both cam seals.

For a few more $$$ you get more parts. eBay item # 221453661739. Or for a seller that I bought before. eBay item # 230953408805 and all the parts fit perfect with not issue at all.

I did my timing belt on my 98 GS300 over Thanksgiving - one gasket did not come with the kit I had ordered - it is the coolant bypass gasket. My TB had visible hairline cracks.

Also remember you need threadlocker, and lots of degreaser, if you leaked oil before. And - most importantly, I had the accessory belt tensioner fail on me at some 193K...very unpleasant because I had to be towed. So, I would highly recommend to replace it.

I agree with Mcon, I also bought my parts from ebay. http://www.ebay.com/itm/Lexus-IS300-GS300-Complete-Timing-Belt-Water-Pump-Kit-/180682670474?hash=item2a1186c18a
Yeah, also both OEM radiator hoses.
-Radiator if the grill looks worn with damaged fins.
-VVT-I pulley, mines started leaking a couple of weeks after doing the seals.

Do the plugs and wires, and boot while you're in there. Check the idler and trensioner too.

Do everything while it's all off, so u don't have to worry about it later. It's better to spend the extra money for oem parts.
