I just noticed this today when changing my oil:



I showed my father and he's never seen that before. He opened the radiator cap and air went inside and the hoses expanded back to normal. Now I'm thinking there is air in the coolant, right?

Happens with both the upper and lower radiator hoses.

Anyone explain why this is happening to my Eg/GSR?

Thanks!

 

You need to bleed the air out of the coolant system...Either run the car with the radiator cap open and add water as the water gets sucked into the motor or open the bleed bolt...
