hello, after I had my 30k service I have been loosing a significant amount of coolant. Just a couple days after the service, I went back and ask the dealer to top my resovior off because it was below the minium line. now, roughly 900 miles later its below the line again. I schedule for them to do a pressure test, but I am wondering if you guys know what can cause this loss. I live in the northwest, which we have had a couple 90 degree days and i occiasionally drive agressively. BTW, i park my car in a garage every night and do not see any signs of leaks.

The first time the flushed your coolant, if it was at the max line, it is normal for it to drop. You are supposed to check it every morning for about 5 days and top it off when necessary. Were you checking it periodically throughout the 900 miles? I would say just top it off for now, and check again everyday to see if there are any changes.

is this just the habit of our cars to loose this amount?

Well, when you get a coolant flush, all of the coolant is out of your system. When they fill it back in, they fill it to the max fill line. You are supposed to check every morning thereafter because coolant is being drawn into the system (which explains why yours was at the min line). I don't know when you checked your coolant, but if 900 miles later and you are under the min line again you may either have a leak, or you just need to top it off again.

Even when its hot outside: turn the heater to HOT.
Maybe there is an air pocket trapped in there too.
And confirm with the dealer (or check the bill) they actually changed the coolant.
Did they use the original Honda stuff?

Make sure they changed the coolant 1st

yes, when i signed the 30k they did check off the coolant and i also noticing their sloppy job. I guess we will al know by their pressure test....and they shouldn't charge me if they did not find anything correct? they also did use the type 2 stuff.
