Used it today instead of the van, usual route out of town 0.7 miles 30 road then 60mph and through 40mph zone for a crossroads approx 3 miles in, normally its just above the 1/4 line by this point, then nope just out the blue zone, 8 miles later shes upto 1/4, took 15miles too warm up today,
Usually she warms up quite quick and the electric/viscous fan set up on the 4.2sc isn't sticking on
Levels good as normal and can see cooling flowing back,
Thermostat ordered,
Yes i know the gauge is just a guide and so on but you know when somthing isn't the same as it was,
 
Got home and got the DVM out. 13.6 V at the battery, so either the battery is dragging the lot down or the alternator isn't 100%. I guess I could swap the alternator for the one on the scrapper and see if that improves matters but it will have to wait for another day.

13.6 volts, is that with the engine running? If so it's too low, even with an early regulator your should see 13.8 volts. sounds like brushes but check the earth strap from engine to chassis. Most likely the alternator from your scrapper will need the Mobiletron regulator upgrade.
