my radiator hose is getting hard i replaced the radiator cap and tried to burp it but its still getting hard but car is not overheating its showing normal operating tempature does anyone know what can possibly be the problem .

Radiator hoses get hard because they're old and need replacing! Has zero to do with how cool your G runs until they break and unload all the fugly green fluid with a smell that takes months to go away!

i forgot to mention that when i drove it a little distance coolant was shooting into the water resavor but it only did it that one time but now when the fans kick on they dont go off until the car goes off.

Hector, replace all your radiator hoses and fluid! That's my best advice...Gary

" coolant was shooting into the water resavor" wtf?
