Ok.... 2 questions about antifreeze ...... there is the GREEN stuff that's been around for ages .... and then there is the PINK stuff. What's the difference and what goes into our S2000?

Thanks

 

there are actually over a dozen different types of coolant on the market.

for the S2000, stick with honda coolant.

 

yeah can you get the Honda coolant ?, it's more of a blue colour. Some aftermarket fluids have silicates which aren't good for the S2K system. My OEM rad was spotless after 9 years on the Honda coolant, I wouldn't use anything else.

 

Honda type2 blue is the way to go. Anything else cruds up. Especially the pink stuff. That stuff is complete garbage. I've seen it countless times over the years completely destroy cooling systems, radiators, and heater cores.

 

Is the Nissan L250 coolant suitable? I have quite a few bottles as I had to use it on my Mitsubishi FTO, standard UK coolants would ruin the coolant system. The Nissan stuff was the right Jap spec.

 

the green is regular coolent
and pink/red is extended life coolent,
but go with honda coolent.

after i get another overflow tank ima have to bleed my coolent -___-
not going to enjoy it very much ):

 

I cannot find a MSDS for the L250 (although I did find some for L248), I would put almost 100% certainty that Nissan has not deviated from the Asian coolant trends of a single organic, silicate free coolant, that Toyota and Honda publically use. You should have no issues running the Nissan coolant.

 

what about the silicate free coolants that are safe for aluminum engines found in most auto stores? Are they ok to use?

 

Stick with the OEM blue Honda, the cooling system is not something to cheapen on.

 

What quantity is required
for a complete flush and refill ???
