what coolant brand should i use to add in
 

i was wondering what coolant i should use to add more to mine, i dont really know what coolant is in there right now, so what are some good brands???

i'm using evan NgP +, and so far its pretty good, you can get some at pineappleracing.com

If the coolant is so old you can't remember what type it is (or it hasn't been changed since you bought the car)then the the BEST (and some would say ONLY) thing to do is FLUSH and Refill the system using a good Name brand Coolant 50/50 mix with distilled water I have always used Prestone or Peak in All my cars.

dont know if you want to go 50/50 in an FD...id say at least 60/40

i usually go 75%water 25%antifreeze. so far its done a good job keeping the temps down.

yea deff flush and fill it, use any good name brand...NOTHING LONG LIFE..the orage stuff is no good for your seals.....
if its green its good :D
