he yall ..ok so the Lexus mechanic told me to flush the coolant on my 2000Es300 which has 100,000 miles..so i was wondering should i change it now? and how can i tell if the coolant in the tank is dirty or not? i have never changed it yet. He said it should be changed every 60,000miles.

 

Have you ever replaced your timing belt/water pump combo? If so, then youve already changed the coolant. If not, i would certainly recommend looking into it soon, your car is 11 years old, its due.

 

ya i did had my timing belt changed but no not the coolant tho...ok then i think i will call them up and have it changed.. i dont think there is any other big maintenance due yet..i guess just spark plugs ,but theres time now..my car has like 101,000 miles on it

 

Yes, change your coolant. If your waterpump was not done when the timing belt was changed, I would have that done next time your timing belt is due, which for your car (I believe) is every 80,000 miles. What is strange to me with Lexus Service Intervals (Always has been strange), is that the Coolant cnanges and Timing belt/waterpump intervals do not seem to coincide. They want you to change your coolant at 60k, then they have to drain it and replace it AGAIN at 80k to do the TB/WP. In my professional opinion, if you change your coolant when you do your timing belt/waterpump, you should be ok.

 

Actually, it makes perfect sense. The water pump does not have a service interval... We CHOOSE to replace it because the labor to replace it is the same as timing belt labor, but, we are typically replacing these thousands of miles or years before they will actually wear out...

 

You are right, LOL, I stand corrected. You just always hear (on this forum) them being changed together, and I have always reccomended it on a pump driven by timing belts, so that fact actually never entered my mind.

 

so ya i got the coolant changed/replaced according to the paper work. m so glad we have some professional here on the forum that we can discuss or get advice. Thanks a lot

 

Toyota red fluid coolant last 5 years/100k miles any ways. I don't change the coolant until i do the timing belt/water pump.
