Re: Heater Core Flush?
I asked the mechanic to check out my heat problem.
He said that my Breather Pipe from the Oil Filter Housing needs to be replaced. It is leaking oil and the oil is the smell that I get in the cabin. Also because there is a leak it affects the pressure and the amount of heat that I get.
The mechanic seemed top be quite good.
does anyone here know how I can verify if the Breather Pipe from the Oil Filter housing..really needs to be replaced....is this something that can easily be seen?
I am sceptical about this diagnoses
thanks

Re: Heater Core Flush?
As previously mentioned, try the flush first (including reverse flush and even compressed air if needed) and if it does not work then replace the heater core along with all new G12 mixed 60/40 with distilled water for cold climates. Do not exceed 60% G12 / 40% water mix.
Replaced a heater core on a B5 A4 and opened the end tanks on the old core to see what was going on. Every vertical tube in the core was plugged at one end with brown fibrous material about the size of a pencil eraser.

Re: Heater Core Flush?
My heat isnt working and I get a smell coming into the cabin when i turn the heat on.; Though it isnt nearly as bad or gone when the heater is on manual recirculation.
I was just talking to a new mechanic (well known) who recommended a Heater Core Flush using Kleen Flo Rad Flush
He said they have a pump that circulates this through the heater core and it almost always fixes the problem
They flush it for 1 hour
Also it is only 100.00 plus taxes
My previous mechanic says that flushes never work and I will have to replace the heater core anyway
New heater core is 800.00 (labour and parts)
So I am getting conflicting opinions
Anyone have any thoughts?
Thanks!

The mechanic also replaced 2 breather pipes
so he charged me 159 in parts (breather pipes etc.) 220 in labour and 55 to scan codes plus tax = 500.00
seems a bit high...any thoughts?
ALSO..I picked up my car and lots of smoke coming out of the exhaust..is this normal after a flush?
