[QUOTE="Tourmax, post: 173902, member: 5304"] Got the rad stack pulled apart. It was about as fun as.......well, lets just say it wasn’t fun. Once the shrouds were off, my suspicions were confirmed: brand new radiator. Clean as a whistle and not a damaged fin anywhere: [ATTACH type="full" alt="CF745E84-099E-4972-B695-6C32A199C1C0.jpeg"]30442[/ATTACH] Well thats a little confounding, seeing as the Vette runs pretty warm. So I turn my attention to the evap core in front of the rad. It doesn’t look too bad at first. My AC is “flat” so I just unbolt the lines and pull the core out. Hmmm, some damage, some “fibre mat” and lots of bug carcasses and pebbles jammed in the cores. Could use a clean and fin straightening all around. So I spend the rest of the day with magnifiers, dental picks and fin pliers. Right now, it’s soaking in “scrubbing bubbles” and will get it’s final rinse once thats had a bit of time to do its job: [ATTACH type="full" alt="8F25F609-0313-4895-9EBD-BA7B7389DF4D.jpeg"]30443[/ATTACH] Them back in and we’ll see if it makes a difference in engine temps. There’s no reason why this thing shouldn’t run in the 200-210 range all the time the way I drive. No traffic to speak of, reasonable speeds, reasonable ambient temps. It should not be pushing 225-230 all the time.... [/QUOTE]
