Air build up in coolant, thrown out from cap of reservoir
99 Ford Taurus.
- started to have clanking noise 2 weeks ago
- sent to MIDAS yesterday, got the water pump replaced, cost me $420 :(, noise is gone.
but it started building air in coolant and once engine gets hot, the high pressure (due to the air) throws coolant out of reservoir from the cap. it never had this problem before. could that be the mechanic did something wrong?
the mechanic could not tell exactly why, he said it might be the Gasket head leaks, but to replace it will cost at least $1200. he suggested not to drive it too long to make engine too hot, and checking coolant before every drive.
what should I do now?
