Realize this is a bit of an older thread, but..... recently after a rebuild (new Isuzu Thermostat 82degree) and a bad sender I replaced with a new VDO sender/gauge. On the old sender/gauge (original) prior to rebuild temps looked to be closer to 84degrees (sometimes shooting them with infrared sensor) but with the new gauge the 4BD1T is showing consistently 90-95. I've been doing mostly hardpack and city driving for these first 500km since getting it back on the road. Also, FYI, flushed the radiator during the install. Should I be concerned? Is it possible that the engine was always running like this and the new sender/gauge are just now displaying it correctly? Other than testing the t-stat (already done) and pulling to more closely review the pump, are there any additional suggestions?
