Default Coolant hose under supercharger



Has anyone replaced the hose that goes down the center under the manifold? It looks as though the supercharger has to be removed?

There's only 20 or 30 threads on it, done in quite detail also, there's 2 lines. Do a search for supercharger coolant lines x308.....and yes, the SC has to come off.

Iíve basically decided since itís a 2-3 hour job pulling the s/c Iím doing everything that can be done. Valve cover gaskets, knock sensors, new pulley, rebuild the snout, have the s/c checked for clearances and rebuilt if needed, all hoses, and since I already removed the throttle body Iím gonna strip it down and thoroughly clean it too.

That is usually the route most folks take when accomplishing this task. Be sure to clean up the hose connection ends you don't replace (trim off the stretched ends) and you'll find better performance there also.

First time I did it, it took about 5 hours. Also, the first time I did it, I didn't replace anything. A couple of months later, I had to do it again because the heater hose ruptured. The second time around, I made sure to replace everything necessary.

Not sure what your plan is for the supercharger, but I would at least change the oil, and coupler (use a new OEM coupler).

This is what I did. Everything I removed got replaced or cleaned up. It was a PITA to be honest.

Replace the part load breather tube while you’re under the SC. It will be extremely brittle and will probably crumble when you touch it, but it is plumbed to the intake elbow under the throttle body, and you will have a massive vacuum leak if you don’t replace it, even if it looks ok. It happened to me. In my case, I was able to replace it later because the line does not HAVE to run under the SC, but life would have been simpler had I just replaced it while I had the SC out. Also clean out the port where the part load breather tube goes into the engine in front, using a small drill bit, held in your hand. Do not drop the drill bit in the engine! I clipped a small vice grip on the drill bit to be safe.

Might as well change the SC oil while you have it out.

One other thing you might want to consider.
Brass insert on side of TB elbow. C2S15816
You wonít need to replace the brass itself but, the o ring inside along with the plastic retaining clip most definitely will need replaced.
