I have a 2004 honda accord and just replaced the thermostat. The car ran hot and after replacing the thermostat and refilling wiht coolant it's still blowing cold air. what could it be?
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.
