^^^^ hey, cool tip!

 

Yes every year in September!

 

It is AUDI approved cooland and comes straight from Black Forest. It does not have any silicates to form residue.

Turns out that after rad flash we are supposed to park the car uphill so the fluid from the reservoir can flow into heater core which is located quite high
(as per my mechanic), if we are too lazy to bleed it , as it is in my case.

 

Check your oil! Hopefully it doesn't look "milky" but if it does, that means your coolant is mixing in with your oil. Usual suspect, blown head gasket!!! I wouldn't be surprised since you like to use "additives" to your car (i.e. Nitro, 2T oil, etc.). Ho ho ho-Hopefully that's not it though!

 

Good rhyming!

This is exactly what happened with my Volvo before it lost all compression.

I had an air pocket in my heater core this time.
My mechanic told me to park on a ramp uphill so the air pocket could escape.
One of these little secrets - what to do after rad flash.
