Good morning all,
The old radiator core had 62 tubes in two rows, and the new core has 81 tubes in three rows. The car runs so much cooler than it did - vey happy about that.
After about two and a half hours if driving the coolant level is about 1/4 inch over the top of the tubes. So throwing coolant out the overflow is still happening.
I've read that some owners have ground down the impeller blades to slow the flow assuming it pumps coolant faster than it can flow through he radiator. Hard to believe but I am stumped.
I'd appreciate comments on you experiences. Thanks.
