BTW you can't say That about the engineer.
He's horizontally challenged!!
Any water in any direction thru your rad running or not helps plug it up.

The flap was seized in the closed position, Bob

Geezer, I checked, it's only got a 1 core Rad in it, maybe the PO changed it when he did the motor.. Horizontally challenged..LMAO
Nonstop, You know that could be it, lord knows what this PO did under the hood, but it seems to be grabbing just fine, I went for a ride earlier today and checked to see ho it would spin while it was at full temp. It stops moving as soon as my hand quits moving it. The PO left a rats nest of wires under the hood from the Diesel engine so I've had fun grouping all the extra stuff together, and bundling it all off to one side.
Burkeftm, I wish it was that simple, but I went to headers last fall, before it got cold, so that thermal flapper isn't even hooked up. Good thought though.
Blessed66, since mine started out as a Diesel it never had that converter on it, thank god. But a good idea though.
