So My 1LS with 185K is dumping the water pump. Gonna have mechanic replace it so I figure I'd take care of some other things while the engine's disassembled. What do you guys suggest?

I've got so far:

distributor rotors and caps
spark plugs

thats about it.

you can buy a kit with timing belt, water pump, guide pulley, tensioner pulley and tensioner for between $200 and $250. All of these are a definite should replace if you are replacing water pump.

definitely install the Aisin TKT-030 kit - it includes AISIN Water Pump, KOYO Idler Bearing, NSK Tensioner Bearing, NTN Hydraulic Tensioner, Mitsuboshi Timing Belt - all of these are the actual brands that were on your Lexus when new!


also, I would add cam and crank seals, and a woodruff key to that, all in genuine Toyota - and a set of NGK or Denso plug wires, and ECT sensor if it hasn't been done.




make sure the mechanic uses genine Toyota red long life coolant and distilled water!

Big help thanks guys



WHAT'S A WOODRUFF KEY?

a tiny little piece of metal that keeps your crank pulley in the right place

Toyota p/n 90280-05005 - about $1

Thermostat is also a good idea. The bleed hole at 12 oclock on the install.
