Personally, I would just drain and refill and not bother flushing with water unless there’s a rouge brand of coolant in your system. Follow the procedure for draining (radiator, res, and engine block if there’s a plug) and refill with Honda coolant. Eric has an awesome how-to on bleeding the cooling system and he uses a no spill funnel which looks like a great way to get all the air out the system. I have never used one, but it’s something on my wish list 🙂

you could always drain it again in a few weeks if you are concerned with “flushing” – but it may not be necessary.
sounds good. post back for any other issues.
let me give you this video to help with bleeding the
cooling system.http://www.youtube.com/watch?v=zUpXgAJ1 … plpp_video
I all the years of working on Honda’s I think I’ve flushed a system once because it was so full of debris and I had no choice. Even at the dealer all we did was drain and refills and there weren’t any problems. In fact these days the coolant is long life coolant and I don’t do anything with it till I change the water pump at 100K. My point is there is no benefit in my opinion to a coolant ‘flush’ unless you have a contaminated system.
Honestly genuine Honda coolant for that engine would be a waste of money in my opinion, it’s only later models with the ultra low silicate formula where it really matters in my opinion. Contamination would be either from sediment or oil contamination so if it’s full of rust or debris or looks like a chocolate milk shake then it would require flushing but if it’s just old green coolant a drain and refill should be fine.
Hello Eric:
First of all, I would like to say,”Thank you”, for the tip you provided on Youtube for fixing a stripped out oil pain. You provided me with a $1.20 solution for a $350.00 plus problem.
My question relates to the posted topic of flushing and filling a Honda Civic. I’m the proud owner of a 94 Civic VX with 234,000 miles on the odometer and I would like to do complete flush and fill. The question is whether it’s okay to use a garden hose to flush out the cooling system, or if it would be best to use distilled water instead. The current argument provide on another tech site is that tap water from the garden hose can leave corrosive sediments…your thoughts are greatly appreciated.
I’ve only owned the car for about six months, whereas I’ve no idea if this service been done before. This is really for my own piece of mind, plus I already have a gallon of genuine Honda coolant.

If the system doesn’t have any sediment or debris in it, I would leave it alone. All that’s required is a drain and refill about every 30K or so. Outside of that, flushing should not be necessary. A side note, I often see those ‘T’ fittings that you put into the system leak. That said, opening up the system that way might not be a good idea. Also, anytime you open a cooling system for service, you MUST purge the air out when you’re done to ensure proper cooling system operation.
