Distilled water necessary?

[kcpope]

Just had the timing belt / water pump / thermostat replaced on my truck at 105000. They also did a cooling system flush and refill. However, they didn't use distilled water. Should I be concerned? I live in Southern California. Thanks

Distilled would be good practice. If you don't have a lot of minerals in your water then you are likely fine.
Makes me think..does the dealership use distilled water ?

They sure charge enough to put it in. MIke

And if anyone is curious, I had the timing belt / water pump / thermostat / accessory belts / oil change done for 850 including labor.

It is pretty standard practice to use distilled to reduce the deposit-creating minerals in the water. But it would certainly save a few bucks to skip that step.....
