Just watch the wire harness near the EGR tube when you run the hose behind the blower.
Is it easy to do the delete? And what’s the benefit of it?
I have not yet finished doing the complete delete, but so far it has been easy; however, my motor was out of the car so that made things go a lot smoother. The hard part would probably be removing the tube that goes from the manifold/header to valve since it's a tight squeeze.
From what i read, it helps in lowering IAT temps and it cleans up the engine a bit. I've read of other makes and model doing this delete so it should be a good mod to do. Plus it's cheap.
So I’ve taken off my blower and intake manifold, I got my frost plug out ondriver side head. Do I have to remove the passenger side aswell? And why remove the heater core hoses
you do not remove the passenger side freeze plug, just the driver side. That is where the long hose is going to plug to. Then it will run from the back of the s/c, under the plenum, and connect to the thicker hose exiting the s/c reservoir.
You need to remove the heater core hose to remove a little small washer located inside it.
What’s the point of removing the little washer from the heater core hose? I just want to know why I’m doing what I’m doing
There’s one fitting that looks like a L and there’s one long hose and one small? What’s the small and the L fitting for?
i believe the instructions said something about the coolant flow increases when that washer is removed. I've read of some ppl not removing it but i did because it makes some sense.
the small piece goes over the bass fitting that you attached to the freeze plug and the L attaches to that small piece. You then attache the long hose to the L. Point the L a little toward the firewall so the hose can go around the back of the s/c a little easier
Do you have picture that I can see please?
I have one. One sec
And did you clean the intake valves or clean anything before re install? And did you have to file anything on the fittings
And does that plate on the fitting go into where the intake bolt supposed to go?
Yeah, blower out with the intake manifold. There’s no way you can do it with it on.
