Hey guys... new to the mustang world after rolling my miata... just bought a 99 gt vert and the low coolant light comes on every now and then... sometimes stays on for long time sometimes goes off... temp gauge never goes past halfway..... car runs out well.... attempted to add coolant but seemed full w/o an overflow tank. Any thougths ideas or suggestions? Thanks

 

What do you mean seemed full without and overflow tank?

The sensor is on the bottom of the tank, and if I remember cannot be replaced seperately. Check to see if the connector is loose

 

Drain and refill (i believe it's 50/50) and if your still having problems, It's a sensor.

 

Hey guys thanks... I was thinking prolly a sensor... and sorry i wasnt clear this is my first Mustang.. on my Miata it has(had) a seperate overflow tank and rad cap. not together as they are on the stang. I need to drain/refill anyway so that will be the plan. Thanks for making a new guy feel at home. This place seems just as friendly and helpful as my miata fourm. Thanks again

 

No problem bud... Ford likes to use the "degas" bottle on basically everything, eliminating the radiator cap. If you drain and refill, and you know the level is good, and your still getting a light, I'd start looking for a new degas bottle

 

Sometimes when sensor gets wet (rain, car wash) it will pop on

 

THAT explains alot...it has rained here off and on the 4 days i have owned the car... any hints on susp. upgrades for SCCA/Autocross??

 

Do a search, you'll find lot's of info
