Firstly, the shroud is on order from Mustangs Unlimited. I should have it by the weekend.
Secondly, yes I am running a 50/50 blend of
antifreeze and water. The coolant is new so it is clear and a nice yellowish-green colour. However, I just looked inside the radiator and saw that some of the tubes appear to be at least partially gummed up. I had never noticed this before. I am going to go get some rad flush and clean it out tonight. While the rad looks brand new from the outside, it maybe dirty on the inside resulting in restricted flow through some of the tubes.
Thanks for all the input. I will let you know how this works out in a couple of days.
