While I'm not sure how you got 1.5 litre bottles (thought they were all gallon bottles), I would put in 2 bottles of the undiluted antifreeze followed by an equal amount of distilled water. Then pre-mix one bottle at a time of 50/50 mix and fill until full. In case you haven't see the thread, the best way to fill a 530i is by using the auxilary electric pump that is activated by putting the ignition in the II position (don't start it). This pumps the fluid throughout the engine and helps bleed the coolant and allows you to put more coolant into the system befores startup.

Please do not drill a hole on your t-stat. It already has a built in bleeder valve with screw at the top. Unscrew bleeder screw and use that bleeder valve to fill coolant.

I have already installed the t-stat, (I did not drill hole in t-stat) water pump, hoses, belts, etc. and I'm ready to fill up with anti-freeze. The blue coolant I found on eeuroparts.com seems to only come in 1.5 liter bottles.



I don't see any kind of screw at the top of the t-stat do you mean the screw on the hose that connects to the thermostat...that is where the write up in the beginning of the thread says to fill it up from.

also i didnt replace the water pump pully as its just a metal pully and i dont see how it could break....will this be a problem.

Also I would say that at 90k it is definitely time for the DIY cooling system overhaul. It is a safe choice so you don't have bigger problems down the line.


E46, Your fan is probably working really hard when the car is fully warmed up so that it can stay within normal operating temps.
