Hi I have a case of disappearing coolant in my 2003 Prius. There are no visible leaks but when it gets low triangle with! shows up, I top it off with
red Toyota coolant dilute it takes a short time and the light goes off. It first happened last year but now much more frequently. Does anyone know if there is a possibility of an internal leak and if so what it could take to remedy? It is stressful especially on back county roads alone. Could a remedy be done by a non expert without too much trouble?
I have checked for turbulence from the motor and it seems fine but maybe not rapid enough?
Thanks, trying to make it last after replacement battery pack 3 or 4 years ago.
