Re: late model S10 radiator?
I have a 2000 S10 radiator sitting outside right now, both 2.2L and 4.3L versions for automatics and I was almost convinced the 4.3L radiator was a 4 cylinder model it looks so damn tiny.
The core size of the stock radiator for a 4 cyl Camaro is the same size as the 4.3 radiator for a Blazer / Jimmy [our trucks]. The Blazer Jimmy is rated to tow 5,000 lbs. Not sure about the 4 cyl Camaro's tow-rating, but it can't be much. The cooling in my Blazer with 3,000 lbs of boat in tow in Calif desert July heat is more than adequate.
So why is so MUCH radiator required in a 4-cyl Camaro? Compared to a vehicle that obviously needs much higher Delta-T? The Camaro has
electric radiator fans. The Blazer/Jimmy has an
engine driven radiator fan.
BIG difference in Delta-T between the two fan types, for the same size core. Most electric fans move much less air than the engine-drive. Something to think about.
There are also two thickness cores for our trucks. The Sy and Ty have RPO V01 "heavy duty cooling" This includes the bigger radiator, and the trans cooler has an extra plate. V01 may also 'trigger' KC4 engine oil cooler. (Or KC4 is part of 4X4 4.3. I'm not sure).
The difference in price for the two radiators is about $15.00. But you should already have one that's more than adequate with engine drive fan.
