MapTun Silicone Hose Kits

[ChicagoGriffin]

I recently purchased both MapTun silicone hose kits (turbo and coolant) for my 2007 9-5 Aero but I am a noob and want to make sure I have everything down before I install them. Has anyone installed these? Is there anything I should look out for? I suppose I need to drain the coolant and replace it afterwards; is there a good technique for doing this? Do I need to burp the system somehow to ensure no air is in the lines? Have never done much engine work in the past, only simple ops like changing oil and air filters.

Any advice would be much appreciated. Thanks - Griffin UP!

Fairly straight forward, being new (And welcome to the site) I would do 1 hose at a time.
I would pressure wash the engine bay.
You are going to need to remove the plastic shield on the bottom side of engine bay.
On the back side of the radiator about an inch or 2 from the bottom, on the drivers side (LHD) there is the radiator drain plug (****). Its plastic, you need to twist it and the coolant should start draining.
Filling is straight forward, fill the system, run the car a little bit recheck level. if low repeat.
From WIS
Coolant, 4-cyl.
WARNING
Be careful if the car is warm. The coolant is hot and there is a risk of burns from the intake manifold.
1 Open the cap on the expansion tank and release the pressure.
2 Raise the car.
3 Remove the lower front cover.
4 Open the drain **** on the radiator and drain off the coolant.
5 Close the ****.
6 Lower the car to the floor.
7 Fill up with coolant. Do not forget to close the drain **** on the radiator first. For the correct mixture, see . Close the cap.
8 Start the engine and run until warm with the heater control at maximum.
9 Check the coolant level. Top up as necessary.
10 Fit the lower front cover.

Hope that helps some, doing 1 hose at a time lessens the chance of running a hose to the wrong location.
Just noticed my post was censored. the **** is a real word but it is being censored because of its slang.
see reason for editing. LOL sorry

Drain all of the coolant out. Then work on one hose at a time, and start from the back (firewall) to the front. The reservoir is tricky to run underneath, but not difficult. The water pump one is the hardest - you should remove the cobra for more room.

Biggest thing - buy some clamps before you do this. Some of my stock clamps worked, some would not open far enough. And bring a little bit of water or something to lube up the hose so it will slide on the goosenecks better.

Soon you'll be looking like this:

Thanks to both of you! I was definitely planning on replacing one hose at a time, and have already purchased some new hose clamps.

Thanks for the picture too - it will give me a better idea of what the hell I'm doing, and will also help motivate me to get off of my butt and into the garage!

I am not 100% sure what got you sensored, but this is my best guess and correct word is not ****, but PETCOCK....

ChicagoGriffin - so here's an update for you (and anyone else considering using the Maptun hoses).

The hose kits are good for the intercooler and upper/lower coolant hoses. However, there are two hoses that now (after over a year of use) are showing signs of not being the best choice for their placement - the "U" shape hose on the pump and the hose that leads from expansion tank underneath the fuse box and connects near the engine block to the metal coolant line. Both of these - the expansion tank hose more than any - have seepage occur (the expansion hose on a more regular basis, especially under harder driving conditions). It's only enough to drain about 1" down in the expansion tank over a month of daily driving, but enough over time to where I will be swapping the expansion hose back to a new black rubber one (and I will swap out the "U" in the future if/when I have to replace the pump).

So if you do go with the Maptun hoses, I suggest only the ones for the intercooler and the upper/lower coolant hoses (as well as the hose that connects from the block to the firewall).

Just my .02

Make sure you use the right clamps, silicone hoses use special clamps, don't re-use the factory ones, maybe that is why you are getting leakage.

nope - this one has the special clamps - it actually has two and is still seeping.
