hey guys,
I was wondering to see if any one has ever flushed their Radiator with out going to a shop ? I assume its going to be an easy task but I need opinions please..

I assume there will be a bolt under neat the Radiator that I can just open it and wait till every thing is out then, tightened the bolt back and put in new Coolant ha ?

thanks,

[dirtykoala]

you pretty much got it. i havnt changed changed it on my s2k yet, but have done it on my tahoe and my jeep and about 1-2 thousand HMMWVs.
there should be a drain cock under the radiator, i like having the vehicle at a slight downward angle to help the fluid drain. open the drain cock (with the engine cool), open the radiator cap, let it drain, then flush with a garden house through the radiator cap (i fill and drain 1-2 times), there should be instructions on your radiator fluid bottle from here... pretty much just fill with a 50/50 mix and let the engine warm up some and continue to fill as needed, then top off your reservoir tank.

awesome thank you, now does it matter what kind of coolent to put in to S ? or any wallmart brand should do it ? thanks for the help bro.

[dirtykoala]

why not OEM?

[wwevo8]

oh, then I should go to Honda then ha ?

[dirtykoala]

i honestly dont know what the difference would be, ive put prestone in my other vehicles and have had zero issues, running/ran great as far as engine temp. with the S i will probably do some research or go with OEM. im sure OEM will cost more (as in like $10, maybe) than walmart stuff, but even if it was $75 more it would be well worth the 5yr-ish change inteval.

or who knows, maybe someone will chime in, prestone might be the greatest thing invtented for the s2000... coolant is an area i havnt done alot of research on, i just know how to change it.

i do know that i went with royal purple and an OEM filter today and spent $92! and i have to do the oil change myself! better be worth it... have never tried much else other than castrol and mobil 1

so i guess OEM is the way to go

edit

or maybe not, thanks for getting me to read i suppose. looks like you just need a silicate free long life coolant that is safe for aluminum blocks.

thanks for the infos man, now its a lot more clear as far as what im gonna go with ;).

[wwevo8]

:(, I just called to order the OEM honda coolant but they said it needs to be mixed with water and im not sure how to do that one. is there a specific kind that you guys get that comes mixed ready to go ? or you all mix it as well ? thanks,

[slackfaster]

^^^
seriously?

buy some distilled water and mix it...
ratios are on the bottle.

The more water the better the cooling --- but the more likely to freeze if you live (or drive) where it gets below freezing

[slackfaster]

but :thumbup: for trying to DIY

keep it up.

The OEM Honda stuff comes pre-mixed. Don't dilute it more and don't buy it from some place telling you to dilute it.

Don't bother wasting money on flushing the coolant system unless you put something in there that's not supposed to be. Just do a normal drain and fill for the coolant system. But I have a feeling that is all you are asking about tho?

[world of debt]

i like to keep the radiator cap on while its draining, that way the expansion tank/reservoir empties too

[Billman250]

Use honda Type 2 blue coolant. No mixing, ready to go.

I would not flush it with water. This system is one of the best designed and remains completely spotless.

drain the radiator. Small white petcock in the bottom center. By design, the block will drain also.

The most important part is to bleed the air out when filling. Many people have done engine damage by driving with air in the system. This car can go FIFTEEN MILES and be fine, then overheat suddenly.

Bleed until the heat blows good hot air.

[wwevo8]

yeah I was gonna do it just because since I have 80000 milles on it thats all, I just bought the car thats why , so if its not necessary then I leave it as is.

listen to this man..
he know of what he speaks :thumbup: :thumbup:

[redlineracing]

Yep,drain petcock is white about midway under the rad.Turn it counter-clock and remove ,it will drain with a good flow.I use a siphon pump to pump out the overflow/res.

I did mine yesterday ( I change it every year).EZ job,takes about 30 min to drain ,refill & bleed air out.

I use Prestone 50/50 ( yellow bottle).

The overflow is not bolted, it just lifts out :)

Hope this can help.

no I know how to empty it out, but one thing that Im not sure about is bleeding the air out, hmm how can I do that ?

does that mean to turn on the car and after little bit check the radiator and add on more coolant or what ? thanks,

[amok]

bleed screw


bleed plug

Oh, so only need to open the drain plug underneath the radiator? Not one by the engine block?

How exactly do you bleed the system? Is it just by having the heat on max when finished? Should the car be on?

[wwevo8]

anybody knows how to Bleed ?

[starchland]

leave the 2 bleed locations open until a steady stream appears out of them. From what I remember the one near the firewall is the first to purge. After that go for a drive for 3 bars, then let the car cool down, check your radiator and overflow after to double check your work.
