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,

 

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.

 

why not OEM?

 

oh, then I should go to Honda then ha ?

 

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 .

 

, 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,

 

^^^
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
