Tech Highlight: Cooling That Goes to 11
That the ZL1 packages 11 heat exchangers into its powertrain shouldn’t surprise you. Six hundred and fifty, after all, are a lot of ponies to chill. Of the 11, seven are air-to-liquid coolers and four are liquid-to-liquid. There’s an air-conditioning condenser packed in there as well because drivers need cooling, too. Chevy engineers came up with a novel solution for keeping the ZL1’s active differential from cooking its lube. Cooled transmission oil is routed to a heat exchanger inside the differential housing where it extracts heat from the differential oil. An auxiliary transmission cooler is packaged horizontally and sits under a wind-*tunnel-designed cover that protects it from road debris and increases flow through its core. Cool.

Thanks for posting this! I’m really glad I haven’t primed the cooling loop yet, I just drained it a couple days ago and it’s still sitting in my garage. I really should have done more research before I dove into this lol. Any idea what type of trans fluid goes in the cooling loop? I have to say though it was dirty fluid that came out. Not like what came out of the diff but still pretty dirty.
