Re: Overheating Stumped...

The water is not staying in the core as long as it did with the old

Soooo , it's not cooling the water down, like it did in the three row core.
If it passes through the core faster, it doesn't have a chance to cool 
it down as much.

I thought you were asking "any thoughts", "not any donations". :-)
