86 chevy C10 new350 engine overheating
I bought new 350 190hp engine from Summit. Engine heats up after idling for a 3 min or so. Test driving the engine runs at 190* but when I stop for 3 or 4 min the temp starts going up fairly fast. It cools back down once I am rolling again . I had new radiator installed with engine. My truck has AC and it has a 3 speed automatic trans. I found out they "advance auto" sold me a radiator for my truck with no AC and it had a 1 1/4 thick core. They replaced that radiator with one for my truck with AC and it had a 2 3/8 core. Both radiators were aluminum . When I got the 2 3/8 core radiator home I found it was way to thick to work on my truck with the original mounting brackets and insulators. I assumed the thickness of new radiator was making up for the AC condenser blocking air flow. I also have a small trans. cooler in front of the condenser. "Autozone" has a rad. for my truck with AC but it looks exactly like the one from "advance auto"that is for vehicle with no AC. Both of the radiators from both stores match the width,height & thickness of my stock radiator. My stock radiator has always worked fine, it is copper and brass, not aluminum and plastic like the new ones. It was damaged during removal and is not usable. Where do I go from here? Please send me thoughts or suggestions. I cant afford a $500 OEM radiator. Thanks for your help. Big Nick
