Ok. I have all the parts needed for mocking up my Degas Bottle. Its the same idea on the 1993 Cobra R. I got mine from a 95 Probe GT. I have attached a diagram and chime in if you have any suggestions or ideas.... I am not 100% sure if the Degas Bottle has to be HIGHEST point in the cooling system or does that not matter? I am planning on the shock tower location anyways, but here is what I got so far. Let me know if its correct. Also, I realize that I will have to remove the spring from the Radiator Cap so that it wont open up and allow coolant to go through the small attached to the neck of the radiator. Anyone know what cap I should use on the Degas bottle? RS-76?
