Radiator question

As the others stated-you should have about 20-30 degrees drop across the radiator. .

I think you'll find 20 -30* diff at idle under no load, would be very close to overheating under load with high ambient temps. (summer).. unless it's a very small (4-cyl) engine

If you go shoot the temps of different cars you have access to (I did),, I'd be very surprised if you didn't find the average to be well over 50* difference on a well maintained or new car..

I shoot the actual rad fitting,, not the hoses,, they seem to squew the temps..

Go check it out,, find out for yourself,.. I'd be sendin the rad out for service with a 20* inlet/outlet difference..

that's been my experience

cheers
