Re: 67 Chevelle Aftermarket Radiator
Because the temp comes down when you start moving, part of the problem is insufficient air flow. What kind of fan is it, the factory fat blade type? If it is one of those narrow blade replacement types, it could be part of the problem.
What size electrical fan, and what is the CFM rating? There are a ton of undersized, underpowered electrical fans out there. Make sure yours is adequate.
