260270 degrees is real hot by VW standards(assuming your guage is accurate).
In the old hot rodding VW engines book from the 60's, they said for every 10
degrees your engine runs above 200 degrees, it cuts your engine life in
half!!! Check guagew accuracy by removing temp sensor(VDO aftermarket I
assume) and set up your camp stove and boil water. Assuming your near sea
level, the water will boil at 212 degrees F
stick the sensor in the boinling water and turn on the ignition so juice
gets to the sender and rig up a ground clip for the completed circuit.
Won't take long for the reading to show how far you're ofI rigged up an old
Harrison evaporator condenser from a 75 Monte Carlo's AC and welded 2 1/2
inch aluminum pipe thread fittings on the inlet and outlets, and rigged up
an Amot in -line thermosatat. Add the Aeroquip teflon/ SS braided hose and
the swedgemated fittings and voila!: You
hAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAZZZZZZZZZZZZZ
ave 200 degree oil on a very hot day. Airflow was through a semi
sophisticated sheet metal conduit stealing the air from the side louver.
This was a 79 busss
