Since early April I have been preparing the GMC for our family trip out east. Longest trip so far in the GMC. 9 days 1500+ miles. We are meeting my brother and his wife in Seneca Rocks WV. We will camp there for 3 nights then on to Williamsburg for 3 nights. From there we spend two nights in Chincoteaque Island however we will be in a hotel. The onto my brothers place in MD for a few days. Should be fun....and uneventful I hope!

So since April I have installed the Rockwell intake, repainted the dash, side panels and front cap, and installed new carpet. Also installed NOS airbags (which by the way made a nice improvement to the ride!), installed new Norcold fridge, installed macerator and last project, so I thought, install a Dakota Digital cruise control. So the last thing I wanted to see was the radiator leaking just a week before our trip...sheez in never ends.

I checked out Gene's GMC info site and saw the write up about removing the radiator with out removing the frame it sits in. I gotta tell you it works like a charm. I took my time and did it under two hours. Could probably do it in an hour now that I know what to do. So I will take the radiator in the shop first thing in the morning and hopefully they can have it repaired by Friday. Oh, and to sure I knew were the leak was I rented a pressure tester from Autozone and pressurized to 7 psi. I found the leak write away.

I also tested the cap. I pumped it up to 9psi and it would pop the relief valve. Then I pumped it to 7psi and it leaked downed quickly so I will replace it. I checked Gene's site for the cap too and found a few PNs. NAPA has a cross reference for the Stant but it is a 10psi cap. Would the be okay to use?
