Hi,

I have a quastion about procedure.

1. I have to start engine or only acc?

2. After prees accelerator pedal for 10 sec should realise and press for 1 minute or still hold for 1 minute?

4. During the bleeding the fluid container should be open?

10. How can I check if I have Vacuum System Filler

Thanks
Karol

That is the correct procedure. 

 

1) You must start the engine (not acc mode) because the engine must run to heat the coolant so that coolant temperature reaches higher than about 182 degrees minimum to start to open so the thermostat.  Coolant can then be circulated via the cooling pump through the engine and all parts of the system to remove and air pockets.

2) My guess is that by holding the accelerator down for 10 seconds immediately after brake is released initiates the coolant fill mode where the coolant pump will run at 100% and the car will stay in that fill mode through the entire process. Then you move to step 3 which is to hold accelerator down for one minute.  I believe you can either release accelerator after the 10 seconds or likely just continue to hold accelerator down for one minute as the car should be in the fill mode.  Have someone listen for the pump running. 

4) Good question,  I would put the cap back on after each fill of the degas bottle.

10)  Disregard the Vacuum Filler as you are not using that tool to check for leaks and fill the system with coolant.  There are videos on youtube.

 

Let us know how the procedure goes.

I have to add some coolant to the ICE like once a year because it gets below the MIN mark. Every time I add, I see some coolant leaking on the floor and I don't know where it comes from. I didn't spill any and only added to get it up to the MIN mark again. Is this by design so you don't accidently overfill it? Anybody else experienced this?

The car is not overheating and I don't see any leaks on the floor other than when I add.?

Sounds like you potentially do have a leak somewhere that would need to be tracked down. Should be able to fill it up beyond the MIN mark easily and in theory should be able to fill the bottle up to the cap (obviously not recommended). It's designed to be a sealed reservoir and pressurized by the cooling system when full hot.

I bet you're checking coolant level when the car is cold. Try checking it when the car is warm and on a level surface. Your leak could be from overfilling.

Just found out that the coolant reservoir has an overflow tube somewhere by the cap. I must have accidently pointed the funnel in that direction while filling up the reservoir, hence the spilling of coolant. Guess because of the bad location of the reservoir, it's hard to get the funnel into a straight position while filling.
