My SC400 has a misfire. So I decided to do a 90K miles tune-up as well. It's at 84XX. I took it to a Lexus dealer and they told me that I need to change the Idler Pulley, and the water pump. Aside from Plugs,Rotors, caps and wires, Timing belt etc...What else do I need to look for? Since I am NOT taking it to Lexus of Manhattan (they want $1700). Does anyone have a complete parts list or knows where I can buy them for a reasonable price? Any help would be appreciated.

 

1700 is kind of expensive look for another lexus dealer.!

Is that parts list for an SC400?

 

My mistake.... reread your note and see you make ref. to an SC 4....... what milage did yoou have on it when you did the timing belt and water pump? I've got 160K on mine with original timing belt & water pump..... checked it (timing belt) at 135K when last tuneup was done (plugs, wires, caps & rotors)and it looked great so I left it alone although, I've heard of water pump failures in the 150's so I know I'm due.

 

Yeah, 95 SC4. It's my gf's bro's. It's at 170K and the t-belt is due, original belt too. I did the tune up but the belt needs to be scheduled. During the tune up (cap, rotors, plugs, wires & drive belt), I took a look at the t-belt it's full of nicks. This thing needs to go ASAP, unfortunely t-belt is not something I have the desire to do.
