I've run Dex-Cool in my SVT since about 2k (nearly 4 years later & 40k now)
I love it and it's superior cooling and protection abilities.
Ran it in my 89 Conquest for over 60k and 3 Cavaliers for over 200k.
Never once had ANY cooling system related failures and it's great peace of mind to know you are not getting the particulate build up and erosion like you would the old phosphate and silicate coolant. (I.E. Green junk)
I also run a ~60% water mix to promote even better cooling.
