Thanks PATCH I like the explanation I understand the importance of coolant I was referring to the other post/thred
Where
YNOT SAID Interesting dilema, do you use the coolant Nissan recommend to protect their engines or the coolant the radiator manufacture recommends for their radiator? You should be safe to use either. If your engine is a TD42 I would probably use the GM coolant to protect your radiator warranty, TD42's are pretty tough. Your choice.
