installing a mishimoto rad and hoses in my em1. will supertech be ok to use. and it says do not use water so ...im guessing dont add water? please help asap trying to finish tonight

 

Supertech is pre-diluted 50-50, but it is an okay coolant. For me, it is generally more cost effective to get non-diluted antifreeze and some distilled water. But pre-dilute is fine if you don't want to screw with it.

 

Have you never seen 50/50 antifreeze before? It's premixed. 1/2 water and 1/2 anti-freeze.

 

its fine just use it! yours is 100 to 1 ratio. you need to mix it down to 50 to 1. for example every cup of antifreeze you would add a cup of water to it. its now 50/50

 

OP is NOT asking if 50/50 is OK...don't you read the threads from the beginning? SuperTech is available in both mixed and concentrated formula.

Mishimoto, just as the OEM rad, is aluminum. To prevent corrosion, Honda recommends using their own coolant. The difference between regular coolant and Honda's = SuperTech's is that the later are SILICATE free; silicate promotes corrosion in alum rads.

The answer is yes, it's OK.

grmblemarc...see your point as per my edit comment. Apologies.

 

Believe it or not, 50/50 is a relativity newer product maybe the last 10-15 years, before that it was always concentrated.

Sometimes the bottles are similar and a lot of people do not know that you mix full strength coolant.


Full strength is a better deal if you plan on changing the coolant, you just mix it yourself, I take 2 bottles, one empty spare, pour half the coolant from the full strength bottle into it add the water, and then do the same for the other.
