water pump issue in Camry 2000 LE

Your prices were to high for what was done a pump and belt should not have been 730 as to why he did the oil pump gasket who knows. But to have the motor stop working, you may have alot more serious damage from overheating. I dont know how it would affect the belt but changing it while he is replacing the pump at those miles was a good idea. A regular mechanic might have been 400

Water pump probably seized and broke the timing belt.

A Camry should be letting out red or pink coolant, not yellow/gold/green. Somebody refilled with the wrong coolant (possibly with silicates that grind the water pump seal), and that's probably the reason for the failure. Who changed the coolant?

The parts used look reasonable for a complete job. The oil pump seals is like a camshaft seal. It's good to do with the things apart. Oils seals were a bit expensive at $220, water pump could use "incremental cost" instead of full cost as if you are doing it separately. But that's how they make money. T-belt at $200 is reasonable for a dealer, which means already over-priced. They put on the drive belt for no labor? What a deal ;)

But it's done and you already paid. If you stopped immediately (or the engine did), there should be no harm done.

I changed the coolant around 30k by myself with genuine coolant from dealer. I mixed it with distilled water as instructed.

When my radiator and water pump needed replacing, the Stealership mechanic told me there was a special on timing belt replacement, and to just have the water pump installed along with the timing belt, to save some money. Not sure if it really saved me money, since I remember paying about $400 for labor, water pump and timing belt.

Jiyang, if there's an AutoZone near you, ask them who they recommend as a mechanic, who knows how to work on Toyotas. Give them a try - you might like them more than the Stealership.

Sometimes they just fail early,..its a fact of life.

As the pump bearing starts to disintegrate due water ingress, the pump pulley starts to run off centre or even sieze causing the timing belt (which is driving the pump) to become damaged,..mostly teeth torn off it.

Those prices are typical dealership prices. There is s0ome warning a water-pump is going to shit it's self, but yoy would have to be checking under te car every night to catch the drips of coolant from the rooted seal.

This is the "factory red" coolant I assume. The new factory "pink" is pre-mixed and should not have any more water added. Neither are "yellow", gold, or green.
