Lexusls430-when to change timing belt &waterpump

SOURCE: timing belt replacement 1997 lexus lx 450: when?

well don , if this is a 4wd , actually even if it wasn't i show it to have locking diff(s) , if you have 4wd i show you to have a switch and a light somewhere on dash display indicating if it is locked in or not . , if you look at the passenger side of the rear differential you might see some electronical gizmo attached to it . i recently worked on a lx470 , it was awesome , i cracked the woodgrain cover around the power window switch , ouch , it cost $500 just for that little piece of woodgrain , lexus is very proud of their parts , lol , enjoy that vehicle . i would sure appreciate a FIX YA vote . thank you .

If it is running perfectly I wouldn't think that you would need to replace the timing belt. You shouldn't need to replace that until 100,000-120,000 miles. I would definitely hold off until now unless you have start having some timing problems. Let me know if you have any other questions. Thanks for rating my response and for using FixYa!

There's an old saying in the bush in Australia : "If it ain't broke, don't fix it." It will cost you money to replace something that will probably out-last the life of the car.

mcdevito75 here, If you have 1 continuous belt on the engine (serpentine) then the belt could be worn or the tension pully holding the belt tight could be going bad. No noise in Neautral or Park as increased engine speed in these gears over rides the worn part and thus no noise. On a cold engine examine the belt, look for frays / wear from where the belt rides the pullys. If the belt is 2 years old, Change it.

Hello,
It is very likely that the Dealer is right. In most cases the check engine light is triggered by an emissions problem.

If the timing belt was not installed properly the engine would not start, or at best, would run very rough.

If the water pump had not been installed properly you would have overheating problems, or atleast see fluid leaking under the vehicle.

I hope this helps you.
