Just curious….now that I have a ScanGaugeII to play with and can see the water temp all the time….
Went to Phoenix today, full A/C, going up/down the mountain curvy roads….
Normal is 180,
Went up to around 188 if sitting at light.
Hit 194 when idling for about 10 minutes.
Hit 200 coming up steep mountain/curves.
Goes right down once air is moving.
Needle never moved on gauge.
~ What kind of temps do you see when A/C is going and you're cruising highway speed, air temp around 90?
~ How much does it increase if you're under load for a while (uphill)?
Still don't know yet if fan clutch and blade replacement "fixed" the problem….need a much hotter day…that won't be hard to get if I go down to PHX.
