I have a '95 Golf 2.0 with p-flo/exhaust/p-chip/and neuspeed cam. Summer has began in Vegas and it is starting to run too hot. I take the freeway to work around noon and the temp. rises past the halfway mark on the gauge if I have the A/C on. It still runs a little hotter than normal even without the A/C on. Anything I can do to cool this thing down?
