Please help, I'm afraid I've dug myself a grave. I bought a 2012 RR sport hse lux about 3 months ago. Everything went great with it for about 2 months. Then I got the first low coolant alert. After inspection I found that the back crossover pipe burst and coolant coming from that point. Got it replaced, still had the issue, finally got a thermostat code l, replaced that, replaced front pipe which goes down near the water pump. Since then I have been fighting to bleed the cooling system. Can't get it to work everything out no matter what I've tried. Finally felt like I re pressurized the system, let it run for awhile, shut it off, and now when I start up, I get *Low Coolant Light *Codes P0303 through P0306, and P0316. All misfire codes. I'm truly hoping it's not the gaskets, but sounds plausible. Just wanted to see what I should do/check before tearing the thing apart again. Thank you all in advance!
