Today i got it in place, i see i need a 180 degree 19mm hose, but its ok with a 90 degree (4) but it will be better place with a 180 degree bend so i can cut the original (5) a litle more and get better space between the hose and the stearing, its not any problem now, but it will look better with a 180 degree bend there (3). Nr 2 is a 135 degree hose and 1 and 3 is only a litle hose so the legs on the 135 degree bend is a litle longer so its easyer to attach.
To drain the coolant, remove return hose from reservoir and but it in a 1/2L bottle, attach a hose to the reservoir and blow (DONT remove the cap), fill 2 bottles and then hose and waterpump is empty.
To fill it, i did find out that if i did try to use the waterpump to fill it its not working, there must be some sensor some place so the waterpump dont starts after, you need to remove the power and let the error/sensor reset (remember to find the radio code first). I did find out that its easy to fill it this way
Add coolant to Full in reservoir, place cap in place. place the return hose in a bottle, place another hose in reservoir and blow, blow until the left side in the reservoir is nearly empty. Remove cap and add more coolant (if the bottle is full use that). Attach cap and blow again (remember to not blow so much that there is getting air in the hose to the heater/waterpump). I did this maybe 10-15 times and then most of the air from the system is gone and the pump will start.
DONT worry if the pump dont start, you then need to blow more to get the air out of the system and remember to remove negative from battery for 1 hour.
The next 2-3 days you will hear that there is air in the system, but it gets ok after some time.
This is the 135 degree hose connected to the original waterpump, but i did find out that i needed longer legs on the bend.
