Changing water pump and coolant change?

[rjundi]

When a water pump is changed out during a timing belt(07 Acura MDX v6) change does all the coolant drain out?

My maintenance minder shows it needs a coolant change(by time) now that vehicle has 113,000 miles?

I was not involved in repair. My wife had the timing belt changed during an oil change on day of major winter storm that never happened. So Honda dealer offered 30% off service that day to attract customers so we got it all done for $600(timing belt/tensioner/belt/water pump) which guess is okay for Acura/Honda V6.

You'll still have some in the heater core, block etc. Unless they did a complete flush job I doubt they did any more than dump the old stuff into a pan reuse it and top it up after the job. What did the RO say?

I believe that change most of it out- as the water pump rides on the lower side of things and most of the coolant is drained before they take the water pump out. Check your service order- if there is a charge for coolant- they replaced it.

They need to, at the very least, drain most of the coolant out to change the water pump. They may or may not have drained it ALL out, and they may or may not have poured the used coolant right back into the radiator when they were done. They may or may not have completely flushed the whole system with fresh coolant. Check your invoice.

I would call and ask. If they only use a few ounces to top off, many dealerships will charge for a gallon of antifreeze. There is the nickname, "stealership" for a reason. I'm not insinuating anything about your dealer, but it it couldn't hurt to ask if the fluid was changed rather than topped off. Good luck.

some water will still be in the system up to a 3/4 gallon
