Another diy I just finished... pics speak for themselves... my coolant lines were in bad shape and due for replacement on the pipe joints. I ordered the kit oem and got right into it.
Was very easy just be careful bot to bend the thin aluminum lines as they are fragile. New clips, new oem rubber joints tubbing and I had previously ordered the clip tool to press them and remove the old ones. Minimal leakage is expected when removing the initial joint... just have some rags under the lines... Overall it came out better then if I would have had the dealer do it... my opinion. Now if anyone can help point me to the best cleaner to use to try and cleanup what seems like prior coolant leak stains all over the engine bay on metal parts... I purchased small steel and copper brushes but have not identified the ideal cleaner to remove the stains.... |

Aluminum parts and tubing that are exposed to high heat can have direct effect on anodized finishes ... if it is hard anodized then it's a premium finish vs regular anodized finish. Also the percentage of other materials on the aluminum can be unknowns... those lines get hot AF. Maybe they are oem lines that are anodized treated. Hard anodized is what apple does to their products to keep them from getting marked too easily. These oem lines are super soft and fragile bare aluminum stock. |

The OD is definitely thicker, I would assume the ID would be very close the same they would have to maintain the same flow, I would hope The only thing Im not crazy about the silicone lines is they don’t utilize the factory supports they seem like they just float there Those are Catless downpipes , not sure what brand ,that car is from the the UK so maybe Evolve |

Yeah, this seems like one of those "is it really doing what you think it is doing" kind of products. The "heat soak" is all from the turbo's themselves, and the problem is the factory rubber junction hoses falling apart. You aren't going to add any more heat to the coolant from the air vs the turbo housings it just came from. The factory aluminum tubes aren't going to wear out, and the chance of failure is significantly less than whatever they have used to create that bonded Y fitting in silicone... Replacing hard tubing with flex silicone doesn't really accomplish anything other than look like you've spent $200 on some cool colors. But maybe if they were made out of carbon fiber and saved weight....
--further thought, the unsupported nature of the installation is going to lead to a physical wearing on the bottom of the hoses since they are laying on something with significant vibration. This just doesn't seem like a good idea at all. |

I used a different type of clamp and a high grade high temp hose. I’ll have to find the link for the clamps and hose I used. I haven’t had a coolant hose issue in over 100k miles since completing this mod.

Nice, share pics if possible would love to see what you did.
I recently had to replace a ruptured hose near one of the coolant pumps midway down the front of the engine (difficult to get to). The hose was a special PVC / rubber hose which I ended up breaking trying to change it off. It was brittle. This had me thinking that most hoses can def begin to wear at 90k+ miles… then i realized wait there are like 60+ hoses and most impossible to get to unless you remove the engine lol the S63tu is an insane engine with insane upkeep 🤣 |
