Hi All,
I’ve had a problem with a soft squealing coming from the RHS of my RRS S/C 2009. I took all the plastic bits off the engine tonight and was amazed to see how vulnerable my engine was to 2 bad designs.
  1. The coolant hose to the RH intercooler touches the top of the thermostat housing – mine was seriously chaffed.
  2. The lower radiator hose was rubbing on one of the pulleys (source of my sound). This was about to fail as it had already sprung a tiny leak that was spraying coolant over the RHS of the engine bay. DSC06114.JPG DSC06116.jpg

Thanks for adding to the collective knowledge base. We don't get much DIY stuff on the S/C.

What was your remedy for this?

Hi All - the solution is to make sure the top (intercooler) hose is protected. Maybe wrap with tape. The lower radiator hose needs to be on the INSIDE (towards radiator) of the ACE hose, pulling it away from the pulleys. I have ordered a new replacement (about $90) but the whole lot come as one unit.
See image below.

You could also get some nylon split cable sleeving which is more durable. You can find it at your local AP store or a AV/computer store.

All done and replaced - I had a small issue with bleeding the system. After filling the expansion tank, I opened the intercooler bleed but it would not pump coolant out. I eventually gave it a little suck (yes I know it's toxic) and is came out right away - air lock? Still have the soft squeal when cornering to the left - think it's a wheel bearing or old fluid at least I found this disaster waiting to happen!!!
