Air pocket in the cooling system. Did the old thermostat have a jiggle pin in it and did the replacement thermostat also have it?

I like w/Leather....COOOL~

tennisshoes....we always pulled out the dikes and snipped that "jiggle pin" off altogether....crikey, you've got to have SOME flow to the engine and heatercore~ why this little devil is there remains to be seen...can you explain it?~

Doesn't coolant have "anti-froth" agents added, like Firemen use this on the engine pumpers so that it quickly dissipates the grass fires....would STOP an air-bound condition....I've seen this once on a Chrysler where regardless of how fast we ran the motor or how hot the engine was...it remained AIR BOUND~~~~this very well may be the problem here~ perhaps an anerobic coolant additive exists....will have to research this~

I've had a few air locked systems too, the best way I've found to eliminate them is use a flush machine on the problem vehicles and just let it run a cycle and bingo no more air pocket.

well it ran hot first; then I took it and they replaced the thermostat and refilled the coolant. Nothing is leaking but your recommending that I flush the line to remove any air bubbles?

If you have a machine that is the way to go. It also flushed the cooling system and makes sure the fluid has the right PH.
