2004 Honda Odyssey with 102,000 miles

In October of 2011, I had a Honda dealer do the timing belt service. The repair slip says "replace timing belt, water pump, seals, & drive belts". In the parts section, it shows "coolant type 2 blue" with a quantity of "2".

The car is now 10 years old which is when the owners manual recommends the coolant be replaced.

I am trying to determine if the coolant was already replaced during the timing belt service.

I read on the internet that when doing a timing belt some of the coolant is replaced but not all.

However, the quantity of 2 implies 2 gallons which, I believe, is the full capacity.

I called the dealer, spoke to service, & that person said that the coolant would have been replaced during the timing belt service (but didn't have a ton of confidence in their answer based on the call). But they recommend it be done again for $84.95 as their schedule says every 3 years / 45,000 miles. I figure it's the dealer trying to grab another $85 as the Honda service schedule says 10 years.

Here are my questions for the experts on the board:
- Based on the repair slip, is it reasonable to assume the coolant was replaced already?
- Would that have included all of the coolant or is there still some in the system?
- For peace of mind (we want to keep the car awhile longer) & since it's under $100, should I just have it done again?

Thanks for all your help!
 
Based on your paper work it looks like they did change your fluid. Not to mention that it would be very hard to reuse old one - you'd have to make sure that you collect it and do not contaminate with impurities. If you want peace of mind - you could just test your fluid with tester tool (can get one under $5 at auto parts store) and save yourself $80
 
You should be able to confirm the quantity on the invoice by comparing the price per gallon. If it is in gallons, then it would have been a full coolant change. The coolant change is 7.5 L or 7.9 US quarts.

One suggestion when performing a coolant change is replacing the thermostat as well for preventative maintenance. I had another reason to change the thermostat at the timing belt service - replaced with a warmer one for added heating in the winter months.
 
When I changed my timing belt I only lost a small amount of coolant. Maybe a quart or so. I drained at the engine block and did not disconnect any radiator hoses. Disconnecting hoses might cause you to loose around a gallon or so I'd say. You would have to make a concerted effort to get all of the coolant out of the system during a TB change.
 
I doubt your coolant was changed. Techs almost always religiously follow the work order. "Replace water pump" and "Replace coolant" are two different tasks.

As a DIY'er, I would change the coolant while replacing the water pump. But I am always thinking long-term; techs are thinking the duration of the job.

Have the coolant changed next chance.

OP Here with an update -

I called the dealer & got a much more knowledgable advisor. He said that the coolant is replaced with their timing belt job, specifically the water pump portion of the work. Between that & seeing "coolant type 2 blue" with a quantity of "2" on the invoice, I am going to assume the coolant was replaced.

mrstop - I see you're in Cincinnati, same here.

New Dad New Van - The unit price on my repair slip was approximately $19 or $38 for the 2 so, yes, most likely gallons.

Thanks all for the responses!
 
I agree with Dave. Those service advisors can easily charge in full for something partially filled. I would change it. All you need is a gal. of prestone concentrate and a gal. of distilled water. <$15 at walmart. Cheap. I used this when I replaced my radiator. Will be changing it again next month as its coming up on its 2nd year. Thats unless you are on the side of must use oem blue coolant.
