Timing Belt
I have a 1990 ES250 with 162K miles on it. The last time I changed the timing belt was at 120K miles. When do I change it next? Also I haven't done any other maintenance (besides regular oil change and coolant flush) after 120K. Does anybody have a list of things to do after 150K?

Yes. I drove the LFA.

The next interval would be 210,000. when you do , change the indler pulley and the tensionsers and the camshaft and crankshaft seals, and also the water pump.,
and please dont neglect top change the $2.50 cent PCV valve. it will save your motor. i just had every external (and 2 internal) seals replaced ebcause the factory one was in till 138K, and it was dumping over a half a quart of oil a day.
Good ideas for 150K service:
Fuel Filter
Air Filter
Spark Plugs and wires (if not done already)
PCV Valve
Tranny fluid (DRAIN AND FILL ONLY...DO NOT flush this tranny if your fluid is any color other than blood red!)
Tranny filter
inspect CV joints (inner and outer)
check tie rods and rack and pinion
Struts, (Check em, if they arent gone yet, the probably will be soon, dont be alarmed, its normal wear and tear, this car weighs 4,000 lbs, and its riding on struts designed for a 3,000 lb car, so they dont last as long as they should.)
Brakes and brake fluid
Power Steering fluid flush.

The #1 reason Toyota / Lexus cars end up in the junkyard is because of
improper cooling system care or system neglect. If you have aftermarket coolant in the system, get rid of it and put in the factory original coolant mixture (50% Toyota Long Life coolant and 50% distilled water) otherwise the aluminum componets of your engine could corrode and cause cylinder head gasket failure. Also, after many years of use, aftermarket antifreezes cause mineral buildups in the cooling system which reduce engine cooling efficiency which can cause heat warpage of the aluminum cylinder head which is yet another cause of head gasket failure.
Take off the radiator cap and shine a light into the radiator filler opening. If you see white mineral deposits partially obstructing the radiator core tubes then buy and install a new radiator. Reverse flushing and using radiator cleaners will not effectively get rid of these mineral deposits. Owners who have always used the factory original 50% Toyota Long Life coolant and 50% distilled water coolant mixture at coolant replacement time never ever have any problem of mineral buildup in their radiators.
If the interior core tubes of the radiator are free of deposits then examine the exterior of the radiator and air conditioning condenser. If filled with bugs and dust these need to be gently cleaned with water and detergent. This is most effectively done if the radiator is removed. Finally, buy and install a new Toyota thermostat and thermostat gasket.

it came with green. keep the green in it. do not mix the 2, the read and green togehter if mixed, create a corrosive chemical which will eat and destroy many parts inside your engine.
IF you want to go red, you can, just have the system COMPLETELY backflushed.
i do know what you mean about the mineral deposits saber, mine has them, because the schedule wasnt adhered too, and now i have to buy a new radiator because of it. however you are wrong about them not being able to be cleaned. run enough water pressure through the radiator, it will come clean.

By the way, here in California where only 31% of our people support the war in Iraq, instead of a "Support our Troops" bumper sticker, we are starting to use a sticker that says "Peace is Patriotic Too"

Now I wonder if I could use Toyota coolant in my old GM with 130K miles.

quit trying to threadjack and stay on topic,
I used to do this for a living and still do it for a hobby. I have more than 15 years experience around cars. they have been a part fo my family since they were first invented. that said, if the dude wants to put the green stuff in there (cause its CHEAPER by a LONG shot) then let him do it. It isnt going to hurt anything.
According to JP IMports, the systemhas to be flushed before you can switch coolants. His word is as strong as GOSPEL to me, period. i have known and trusted this guy for a long time, and everything he has said has been right.
but its very wrong of you to try to antagonize my political views in a thread not even pertaining to it. if you have isses with my opinions take it up with me in PM's...jeez. a real class act you are.
