after 10 years gather information HERE and there, I thought I would have the best Pantera coolant system ever.
I have the
MJ 180F thermostat and plate
converted overflow to pressure tank
self venting left top radiator with hard tube to pressure tank.
the over drive pulley
New radiator, don't know brand but from one of the vendors
multiblade pusher fans with shrouds (came with radiator)
a "flowcool" water pump (have not found part number).
During the cooler days (under 50f), cruising about 55mph had the Sniper sender at front of block holding about 180 to 185F
Dropping below 35MPH and stop and go in small town, the temp creeps to 195F.
Today, about 75F, driving substained 70MPH for two hour, the temp ran 195 to 199F. pulling off into town driving temps just went up more 200 to 205. by time back in shed, 210 / 215 and still climbing.
OK, what could be wrong?
1 is it possible the water pump has reversed impeller
2 is it possible the bypass plate is not seated deep enough
3 bad thermo stat
4 trash blocking radiator (just though maybe need to reverse flush radiator)
another observation, from 70F to 180F coolant warmup takes about 5 minutes idling
Along with some other problems, not exactly pleasing day drive
