2207 Pete w/ 2006 ISX 475.. 2007 Pete 386 W/2006 ISX 475.
2007 Pete 386 W/2006 ISX 475. After warming up truck and driving 3 miles empty truck will heat u to190. When arriving to get loaded after 3 miles and While idling it heats up to 200.. Sometimes drops slowly to 195 sometimes fan has to kick on. Once loaded and I drive maybe 2 blocks at 20 miles an hour heats up to(###) ###-####and fan kicks in and brings temp down will do this non-stop until I hit highway. Once on highway after another climb of to 200-205 I can drive for about 3 miles and temp will come down to 180 maybe even 175 by itself... As soon as I get off highway and start slowing down. Temp will start to rise all over again... NOW! Even when empty sitting still temp will be 180 and I start driving temp climbs right away.. even on Highway empty it will do same thing as when loaded.. I did not think that my temp should climb while empty.... If I ride empty or loaded with a/c on temp never moves it stays 180-193.. Cooling Fan cycling maybe every couple of minutes... I have new clutch fan, new coolant, new therm, new low temp sensor and new temp sensor new EGR.. Let me add... I have never seen temp drop by itself with out assistance of fan or driving 70. miles hour down highway... I fill tank until it is past glass. and never have to add.. but lately I have been filling to very top and it will kick it out of overflow until it is above sight glass... Radiator need to be purged? Clogged Radiator Fins? New radiator? No codes … read more
