In the process of deleting the p/s and ran into a clearance problem with the idler pulley and coolant reroute tube.

Would there be any issues with using longer bolts and washers to move the bracket away from the tube? It probably needs to move 1/2" or so. Other suggestions?

Uh, where does your heater return line go?

 

that's what i would do. space it out a little.

 

Yeah agreed that should be fine. Get some slightly longer bolts and shim it out with washers. Check the stacked washers or whatever spacer you use to make sure they are all the same thickness so the pulley stays square with the belt.

 

Ok -will try the washers. Thanks.

If its just a small amount, why not just grind off a little material on the bottom edge of the bracket and paint over the bare metal? I guess maybe the shim idea works too though.

 

Well that's dumb. Can you say heater not working for a long time, and car possibly not warming up?

 

Yeah actually that could work too and is easy if you have a bench grinder or a dremel or die grinder. I like that better than the spacers actually. That bracket is pretty beefy so a little material removal will not hurt it. I would definitely take material off of the bracket and not the tube.

 

I ending up grinding and using longer bolts/washers. Didn't have to grind too much to get the bracket around the large tubing. The small vertical tube and water hose got in the way next so I used 3 washers to space it out from the block.

Yeah looks good. That bracket will still be up to the task. No worries.

I may be doing this myself soon. It turns out my 2871 compressor housing hits the stock mixing manifold so I may have to go to an out-the-front setup like you have. And since I have depowered the rack and have A/C I am using the same tensioner. Hence I'l have the same problem.

 

FWIW I did indeed have the same problem. I removed some material from the bracket but the bung for the turbo return hose has the fitting right up against a good length of the bracket. So I am going to space it out about 3/8". I have the spacers but I need to find some longer bolts.

 

I also had a problem with the front heat shield hitting the bracket - one washer was enough to get it off the bracket.

 

which heat shield? I don't get it.

 

there's a heat shield bolted in front of #1.
