The only US car it might have showed up in was the Cadillac Catera. I didn't think to check at the time. It's the idiotic design that bothers me more than anything else. An air-to-oil cooler was fine for the turbo cars, and for just about any other engine I've seen. Why bury a cooler in the V of the engine? I've heard of these things failing in as little as 18,000 miles. I suppose I shouldn't be surprised after the timing belt fiasco.... Thanks again, GM.
