i have a gallon of honda's type 2 coolant and prestone flush. i was wondering i have to open up the bleeder bolt for the air bubbles to come out when doing a coolant flush?

I would not use anything that doesn't say HONDA, including the Prestone flush. I would drain the radiator, drain the engine block, and refill. When you drain the coolant, not all of it comes out, so some of the Prestone flush will stay in there. Just my opinion.

Take is from a Honda Tech (lol). I wouldn't recommend doing any homemade flush at home, and also stand behind "If it's not Honda, Don't put it in" as stated above. You can drain and refill your coolant, but you only get about 90% or so of your original coolant. Either take it to Honda and have it flushed, or drain and refill yourself! If your timing belt/water pump is close to being due, then drain the radiator the same time you change your water pump and you will get damn near all the coolant out! GL

does honda have their own flush fluid?

I don't think so. At least I've never seen any. Is the coolant that bad, to require a flush? I would rather do two drain and fills (a week apart), than put Prestone in there.

chief, why are u flushing your radiator? U have a ton of miles?
honestly just changing it will suffice. and u can use prestone coolant, honda, whatever- just avoid the $5 gallon special. head to the local parts store and pick some up. a honda mechanic will tell u otherwise b/c, well, they work for honda. I only get my tranny fluid there.

i have 114k miles. dont honda calls coolant flush at 60k miles?

dleccord

also, do our accords have bleeder valves for coolant?

U should be fine. But should be in the thermostat housing. But USUALLY the air bleeds out to teh radiator so u should be fine, bleed it just in case if it makes u sleep better. sometimes we can be way too **** with these minute things. I've used prestone w/ no issues. And i like the lubricating agents in it. I've been working on cars for 15 years and now work in an auto parts and the machine shop. back in the day we used to use drops of mineral oil. he he
my wife, yeah, she;d say something like "only nissan in my car and I need to get a maintenance". $400 down the drain only once. she learned her lesson.

There are reasons that a Honda technician is recommending Honda fluids. Not to make money for Honda, but rather he knows what could happen when someone puts a non Honda fluid in their car. Search around, power steering fluid, radiator fluid and transmission fluid are the three fluids that I would stay with Honda for. Using anything else in those three could shorten the life of the components that those fluids protect.

but i dont understand what's wrong with using the prestone flush though. i mean after the flush, we're suppose to run the cooling system with water. maybe one more time and then i can fill it up with honda type 2.

If you do flush the Prestone out with water, some of it is going to stay in the engine. The Honda coolant is premixed, so even if you knew how much plain water was still in the engine, you have no pure coolant to mix in with the left over water. Drain and fill only IMO. There is a procedure for changing the coolant, it's not just simply drain and fill. You have to turn the heater on, to get the valve to the heater core opened. I don't know if these new engines have a bleeder bolt. My 92 Accord engine did, but that was a completely different engine. I suggest buying a service manual for your car, because even technicians can't remember everything, for every job.
