The biggest difference I've seen in temperature reduction is to get more air flow to
the upper half of the radiator. I drilled six 1.25" holes in the upper radiator
support and made sure the hood had at least 1/8-3/16" clearance above
the front valance when closed.
Kind of crude but made a good 10 degree difference at 70 mph.
Note : You HAVE TO remove the upper support to do this or you'll damage your a/c condenser.
Just amazing how many of these cars you still see on the road, especially since they havn't
been in production for almost 11 years.
I'm also running an in-line thermostat in the upper hose on this car.
Works good but the additional air flow made a bigger difference.
I agree ugly but functional. Can't see with hood closed
This pic is as high as the gauge goes unless your stopped in traffic and then it stays half way between 1/3rd and 1/2
