Twin turbo ls overheating issue

Could always try a Flow Kooler LS water pump.


I use RMI-25 added to my glycol coolant and found it actually lowers temps by 10-15degF


A radiator with 2 rows of 1-1/4” tubes cools the best on my Buick Grand National I bet it would help you with your situation.

I installed my intrepid dual fans using a spare trunk weatherstrip to surround the fan housing perimeter which seals the fans to the rad but also prevents chafing if not installed

I wish I could use another water pump. I’m running the Holley mid mount kit and it comes complete.

Running this kit. Don’t think I can swap water pump. https://www.holley.com/products/ls_...7iIBjMipOzQ69a2RD2zscNijKAzs0akIaAq2VEALw_wcB I’m already running water wetter and the fans for sure are doing their thing. I’ll do some digging on the rmi but from what I just read it’s the same thing. Thanks

Radiator is griffin I forget which one but it is def thick and I got one without Trans cooler for more capacity. Sucks but I think I have to do what I have to do.
