Lexus ES 330 2004 At what mileage does the radiator need to be serviced? Also, does it have an internal timing chain that needs to be serviced?

The 2002 lexus es 300 has the 3.0L engine, which is non-interference. The later lexus es 330 has the 3.3L engine, which is an interference engine. The even later es350 has the 3.5 engine and is back to non-interference as well as having a timing chain rather than a belt. Hope this helps.

Change plugs, air filter and fuel filter. Computer controls all the timing and such. Depending on mileage ( over 100,000) the timing belt needs to be changed.

is there any white/grey residue in your radiator ? if not, it doesn't need to be flushed. change transmission oil and filter every 30,000 miles under normal usage, belts should be inspected at least once a year, a tune-up every fall is also recommended

At 75 000.

has a timing belt and if you need to replace it, if you take it to the dealer it is going to cost you well over $1000. On the ES the belt and waterpump should be changed between 90-120 km

Did You know that its got a "Service interval indicator " which lights up the moment the mileage recommended for the next servicing. If you have driven beyond the recommended distance and/or time period this light glows constantly, untill its serviced again......sodeep

The thermostat is located on the timing belt side belt side of the motor. Look below the alternator, there should be a metal pipe secured to the block with a 12mm bolt. The pipe is attached to the lower radiator hose.

no there is not really a downside dealers are good it doesn't really matter who does it but lexus is more familiar with lexus vehicles than toyota because they specialize in it but something like that is simple .

THE WATER PUMP ON THE 1990 LEXUS ES 250 IS ON RIGTH SIDE OF THE ENGINE (PASSENGER SIDE) BEHAND THE TIMING COVER (PLASTIC COVER)
