Coolant Flush

[Edmondlll]

Any problem using the Acura or Holda Long-Life Coolant (5 yrs, 60,000 miles) in my 1997 NSX? I am currently using standard Honda coolant.

Can you confirm crush washers for water pipe drain bolts (2) as 90471-580-000 (8MM)

Thanks

The washer part # looks good from what I can tell in the parts manual here in the FAQ's. As for coolant I use the standard Honda stuff and follow the recommended change interval. Talk to your dealer and see what they say.

Thanks Brian,

I finally found the #s and they are correct.

I contacted an Acura dealer and the ("regular")Honda All Season AntiFreeze/Coolant has been replaced by the Honda Genuine Long Life AntiFreeze/Coolant Type 2, which is prediluted 50/50. Type 2 is now recommended, but to get its full benefits, all the old "regualr" antifreeze must be removed.

50/50 dilution will be a problem in changing coolant the "easy way"; i.e., not opening all five drain plugs. Those part #s will apparently be needed.
