Radiator Woes

[jonesmw10]

Hey all! I know I'm going to need a new radiator, due to the upper inlet being cracked, but wanted to get opinions on this.. Should the pitting and corrosion on the inlet have me worried? I knew when I bought it (literally 300 miles ago, they just replaced the water pump and timing belt) the wrong coolant was in it. I immediately had it flushed, then noticed the leaking radiator (again, cracked inlet). When I took the hose off, it was in fine condition. I originally suspected that was the culprit. Motor seems to run fine, no overheating or stumbling.

Replaced the radiator yesterday. So far so good. Only took 3 hours compared to my 4Runner, which took 9 (rust!). System seems to be holding pressure a lot better now. You can see the stains on the left hand side from where it was leaking. Transmission fluid was pretty nasty, so that will be my next project
