I have a in-line set up, my temp gauge (aftermarket) runs around 210
degrees, when running at 80 mph in 85 plus degree weather, its a Westy
Camper,the factory gauge runs setting just sitting to...or sometimes
just above the red led light, is this too hot, or to be expected? At
night(55 degrees) it runs at 195 degrees (aftermarket gauge), and at
just below the led light or a needle width below the led light....on
other note I have wired a bypass switch for the high speed fan on the
radiator...if I bypass it drops the needle my two widths (factory
gauge)at a least 20 degrees on the (aftermarket gauge).....This
morning I added "Water-wetter" additive to the coolant system for
s*@t's and giggles ,and it seems to help, but all in all ,does my system
sound "normal" or is it time to look on Ebay for a new
radiator?
