Just a quick update on the car.

 

I can confirmed that I ran the engine yesterday without any coolant for a five minutes but I did a correct coolant bleeding today morning, I filled up 3.5 coolant and 3.5 demineralised water in the the header tank and took my car for a drive for 30 mins with the heater on, the car was not overheat and no strange noise. 

 

I am now worry about my head gasket sorry I am noob

Good to hear mate!

Keep an eye on the coolant level over the next week by taking the cap off once the car is cool..or in the morning and topping off the level if needed

sounds like you're ok - just keep an eye on it.

 

Heater going high is bad - its when it suddenly drops to zero you know you have problems !

 

You'll know if you have air in the system from either a jumpy heater needle (rapid movements), or gurgling noises coming from behind your dash

I found that there is some gurgling noises when I started my car but it has gone away after 2mins. 

Is that mean I have to bleed the coolant system?

 

Thx for helping me out guys, great support

Yep that will probably be some air in the cooling going through the heater core. Common problem on subarus. Not a huge issue unless its constant. Just keep an eye on those temps

Can I solve this problem by bleeding the coolant system?

Yes

[duncanm]

 'yes' -- if you can..  its sometimes tricky.  Someone here should have the magic sequence.

 

I've had gurgling resolve itself after a week or so

I just get the front up as high as possible...turn the heater on with the fan on full...open the header tank cap and either use an upside down coke bottle with the bottom chopped off like a funnel (cut the bottom)...or now i use a proper funnel made to connect to the header tank

Then fill a bit into the funnel...at least an inch and start the car

Let it go through a few fan cycles...and once its warm i squeeze the top and bottom radiator hose pretty hard an it seems to puh extra bubbles out

Make sure theres plenty of coolant in the expansion tank on the radiator and turn the car off...put the cap back on and let it cool down

Sometimes i do that the next day after a good drive too if i have issues like i did lately to get that last bit of air out

There's a diy with pictures somewhere here too
