Been searching and it seems like 205-215ish is ok for my 390 with 195 thermostat ? Hooked up my temp gauge today in a temporary fashion I was pretty tickled to see it stay at about 200-205ish consistently.... When I shut the motor off it climbed to 220 ? is that pretty normal ?
Was a cold mother in the shop and I cant justify any more firewood for a bit but I couldnt resist filing her up with coolant, new hose clamps, plugged her in for a few hours to get the block warm, fired right up, tightened hose clamps when at operating temp and got a good water reading... ended up putting my temp sender in the coolant elbow like many others have, now I have the stock unit which still works and the elbow post thermostat opening reading
That sounds like a good water temp to me. It is a bit over T stat temperature sitting still. Rolling down the road with moderate temps and moderate load, you should probably see 200-205 with 195 stat.
Heat up after warm shutdown is normal for an iron head engine. The heads hold a lot of heat. When the coolant flow stops, heat seeps out of the heads and warms up the top of the cooling system including the temp gauge. With anti-freeze and a 14+ psi cap, it should not boil at 250F+. On re-start, it should cool right down after a minute or so.
I'm getting low on firewood and pellets too.......have burned waaaayyyy more this winter than normal........been a cold SOB....I'm over it!!!! Where in NV are you??? I'm SE Idaho...
