Thanks Leo, no I really do appreciate the point that I will loose 3%/1K ft. Thanks to Rustoholic for the wise words as well. You are all on the money, I feel it will go up just fine if I watch the temp, but getting down, I have to nurse those brakes. Both ways I will have my wife in the Wrangler, with a tow strap and a AAA card for emergency towing! I have another question and that is how full to fill the radiator with coolant? Its the stock '40 unit, with an electric fan on the front behind the grill. It has an aftermarket overflow canister, but I notice that the coolant (when cold) is is about 3" from the cap, so lots of room. Any help here is appreciated as well
