The main lesson is that if you attempt to change your supercharger oil a few days before you drive - then things will naturally go horribly, horribly wrong...

As part of the SC oil change procedure you have to access the fill port. To do that you have to touch the solid plastic hose from the thermostat housing to expansion tank. It's ultra brittle and may crack. you get this:






These are old Ford fittings so if you have the time and inclination you can replace them with factory parts. They are about $30 and can be ordered with 3-10 days wait.

However those parts, in my opinion, suck. This is the recipe for a new line built out of coolant hose and hose clamps.

1. 1.5" of 1/2" heater hose
2. A 1/2" to 3/8 coolant line reducer
3. 28" of 3/8 coolant line
4. 4 good hose clamps.

First clean out the innards of the thermostat housing....get all of the old fitting out. there's a couple o rings and plastic guts in there. Dont worry about the orifice size, the housing takes care of that.

Next, fit up the 1/2 line and one hose clamp. It must be a thinner clamp as you've not got much space.

Set the 1/2 line at about 35* angle...this will prevent the lines from kinking. and put in the 1/2-3/8 reducer. Clamp it.

Plug in the 3/8 line, route it along where the old line went and connect up to the expansion tank.

...comments welcome...at least for today because tomorrow I'm driving this thing to the coast!

 

I have had an almost identical fix in my XKR for the last 4 years!

 

What material was the 1/2 to 3/8 reducer made of. Thank you

 

It's a coolant rated plastic. I'd have a slight preference for brass but was short on time. In this case the plastic held up just fine after a 1500 mile road trip.
