    I guess I either missed plugging something in or botched it entirely somehow? No leaks that i can see but the Pump is buzzing any idea's could i have over tightened it or something? Not blowing hot air either. p0401 i think and the p261b code still even after reset with odb II. Any one have some input?

    ok so i forgot to prime it now after squeezing the hoses I am getting heat but theres still a lil buzz not as bad will that bleed out over time or did i over tighten? I saw there's torque values for it but who can get a torque wrench on those bolts its so tight!
