mikie Posted June 19, 2007 Report Share Posted June 19, 2007 So my fan hasn't been turning on so I decided to change the thermostat, temp sensor and the relay. One thing I noticed when removing the 13mm petcock in order to drain the coolant is that it started coming out quite a bit before even opening the cap on the radiator over flow bottle. Is this normal or does this indicate a leak somewhere? Thanks Link to comment Share on other sites More sharing options...

ViperVette Posted June 19, 2007 Report Share Posted June 19, 2007 yea, the gravity pulling down on the liquid would overcome the surface tension. Therefore it would pull air in through the hole as well as let out fluid. Link to comment Share on other sites More sharing options...
theForgottenone Posted June 19, 2007 Report Share Posted June 19, 2007 yup...absolutely normal for gravity to work. Link to comment Share on other sites More sharing options...

MrWinkey Posted June 20, 2007 Report Share Posted June 20, 2007 Unless you had the car upside down... then that would truely be a marvel. Not if it's hot and under pressure though! Think about that ;) Link to comment Share on other sites More sharing options...
mikie Posted June 20, 2007 Author Report Share Posted June 20, 2007 Not if it's hot and under pressure though! Think about that Exactly! I thought there would be sufficient pressure (even at normal temps) that there would be the need to remove the cap on the radiator over flow bottle in order to drain the fluid. Thanks guys!
