Yeah, those stupid under-the-blower coolant lines. I have zero idea specifically what and where these are, and since my shop contractor failed MISERABLY for a year now as I still don't have my shop built, I may bite the golden bullet and maybe pay a shop to do this simple task... but now they are asking which lines need replacing before they will even ball-park the cost for me.
I figure items 12 and 13, and maybe item 22???

 

Hoses aren't a high cost item (IIRC around £86GBP) it's removing the SC that is the labour intensive bit

Sadly don't have the receipts as of today as sold my 5.0...otherwise would have given you all the part no.s

If not already done then get the plugs, fuel pump, SC oil done withe the SC removed..

 

I was going to do everything within reach once the top was popped. Plugs done a couple years ago so those are fine. I will change the S/C oil and coolant, probably the pump also, unless someone screams at me "DON'T!"

 

Been there, done that Cee Jay. DO! great piece of mind. and no leaks.

 

So I guess nobody knows if it's lines 12 and 13 or not?

 

I know 13's the crossover. Don't recall what 12 was, it may be the back to front line. Regardless, you should be replacing EVERYTHING. I listened to the main dealer's techs and ended up having to R&R the super charger 3 times over a 1 year period!!!! Don't know what to tell you about the coolant pump, you've been lucky. Perhaps it will fail soon, perhaps it's got another 20k+ miles to go, but o-rings, seals and gaskets fail with age and use (heat) and the oil tube's another common one on the backside of the pump.

EDIT: Also had to replace the radiator, hairline micro split at a seam, part was cheap, so again I emphasize EVERYTHING - I've also found with age (mines a 2015) clamped fittings ALSO become weak spots.

 

Interesting you are posting this. I have some super light coolant loss...but am not sure from where. I was going to get a pressure-tester and see where the lovely-smelling coolant was escaping. I want to get this sorted quickly as I am taking my 5 liter to the track next month for a full day of high-performance driving. Can't be the guy that spills coolant all over the racing line... Luckily for me, no supercharger.

 

You didn't mention number 9. Isn't that the 'valley hose', a.k.a Throttle body heater hose (AJ812140), that is impossible to change without removing the supercharger?

I changed it when I had the snout changed on my S/C.

 

I don't know if it helps, but I did the hoses in 2018 (and all front pulleys and water pump etc at the same time). Here's a picture of the parts I got for it at British Parts, and the sequence in which to do the whole job.

 

Thanks for that, although Cee Jay has a 5.0, this list is great for the 4.2 folks.

 

I never saw that one, I'll take a look again. Thanks.

 

Cee Jay, how did you determine that these hoses were leaking? Just curious on what to watch for with mine...Did you see coolant pooling somewhere?

 

Orange residue on the torque converter cover behind the engine, in front of the firewall. There is a bit of orange goo where the coolant leaked and then dried. Also a small puddle under the car about where it would drip from that location.
