Help! Running hot

- What aluminum radiator do you have? Their cooling abilities vary all over the map.
- And what flex fan brand/model?
- And as asked in post #2, under what conditions does this occur? In slow traffic in town, or at highway speeds? This answer is important in pointing to the right solution.
- Do you have a good seal between the rad and the core support, and between the core support and the hood?

And yes, the lack of a shroud WILL make a big difference if the overheating is in slow driving/idling conditions.

You gotta help us to help you, with more info.
