I have a 99 rs 420a when I bought the car I replaced all the gaskets from top too bottom,also have replaced thermostat and radiator cap due to air getting in the system and causing coolant to bubble out into the overflow tank, that was about 3 months ago..
Tonight made a 50 mile trip when I shut the car off I heard the sound of the coolant bubbleing again into the overflow tank, I checked the fluid and it was a little low, topped it off and made the trip back home and no more bubbling but still hot under the hood any input would be great maybe how to keep it cooler under the hood?
Have a short ram intake with a flex tube from the fog light roted under the hood and a breather valve on the valve cover no new headers yet heard that might make a dif..
Thanks
