Had the oil filter housing replaced on my audi a4 2007. Noticed the coolant reservoir level went down. It was over the max level and when I checked it the next day it was lower than the minimum level. It had not done that before the oil filter housing was replaced. Could it be a related issue, that perhaps something was moved at the time of the other part being replaced? What can I do to fix this issue?
Don't forget the bleeder valve located on the coolant pipe that runs next to the valve cover under the plastic cover(with the Audi emblem)that goes over the valve cover.
Nice video.....can I ask a question? The question is my Audi currently has oil in the coolant system and the mechanic I have repair my car said its not the oil cooler, turbo, oil cooler flange and something else but I forget......he thinks it's the head gasket, but the oil is fine zero color ,the oil cap is clean and the engine runs fine never getting hot.
shaggybuddzz head gasket or head could be cracked on coolant side letting oil leak in coolant also could be from previous head failure from previous owner. if you bought used
This guide is missing a ton of important information. G12 coolant does not come premixed. You must mix it 50/50 with distilled water. You will need to open the bleed valve on the top of the coolant hard line and let it burp the air out. Or you will have massive air pockets in your cooling system. Bad for your engine and turbo! Last step is to burp the end of the cooling system at the top heater core hose.
Thanks for the info. Is there a way you can add a pic of the bleed valve on the top of the coolant hard line. Sorry for the ignorance, I just want to make sure I got the correct one in order to flush the system correctly. I'd appreciate it.
hi.....i just bought me a couple of bottles of G12+ coolant. it says on the bottle do not mix with water. it was on sale at my autoshop so i grabbed me a 6pack carton...so i have now 6 litre of coolant.....and you are telling me now i will have to mix that stuff?...lol i dont think so....😉
This is a very incomplete video.Draining as shown will release approx 2.5 litres of water, leaving about another 4 or 5 litres plus, in the engine. You have to undo an allen screw at the rear of the engine to release the rest. This is just above the rear of the mounting structure on the rear/left corner of the engine. There is a very small groove pressed into the mounting bracket to facilitate getting an allen key into the drain plug. Its about 6mm or maybe slightly less screw.
Hey buddy great video 👍. Im doing a flush on my 2007 audi a4 3.2 engine but im having trouble finding the drain plug on tthis coolant system !!! Do you know where is it at? Thanks 🙏
This has been the worst description on how to bleed the system I’ve ever seen. Let’s not forget that you have two bleeder holes generally. On on the heater core hose and one on the hardline that runs parallel to the fuel rail. These cars don’t self bleed well you have to rev it up to about 2k for a couple of minutes to allow all the air to escape.
I dislike when people use the terms "drivers side" and "passenger side", as it can vary between countries. In the US drivers side is left, but in the UK it is right.
thank you its nice but for my car temperature is 90 normal but engine can not touch very hot even all engine room what i have to do i had replace radiator already regards
may i ask, I am working on 2007 Audi a4 trying to drain the coolant, but I turned opened the drain the coolant does not come out. it can be turned only half way. I can see your finger turning it opened easy. So What other way I can get it drain or what can I do if it is clogged? Many thanks
+Siang Iu'Mienh Hleix an alternative is to remove the lower radiator hose and let all the coolant drain from there. Hope this helps you out. 1aauto.com?RUclips&CTA%20Comment&ATony 866-403-3393
This may be a stupid question but did you have the coolant cap off on the top? Pretty sure its pressurized so if the top cap isnt off the system will still hold the coolant.
You need to turn tap through 90degrees anti clock, pull tap out then turn further 90 degrees. I ended up using a pick up the nozzle to get the tap to initially pop then a flat blade behind tap to get it to pull out to second pozn
I was having the same issue. Actually you need to pull the valve plug (not just twist it) it will come slightly outwards and then the coolant will start to come out.
So I detached the hose attached to the drain valve, and let all the coolant drain. Then I filled the reservoir with the pink coolant. After driving the car the reservoir is filled with greenish coolant again. In thinking there is a different hose that needs to be removed for the entire radiator to drain. Any advise?
gfult001 coolant has to be flushed several times before....cus if u flush it once and right away and be done with it ur gonna get that old coolant and new coolant mixed causing color change......now if u flush several time before actually being done with it, it will come out all pink....so think of it as a rainboe chart starting from old coolant to new pink coolant....having a clear party cups help to see each flush u do that way u know ur system is all pinkd up
If you are switching from green to pink coolant or vice versa you (it is always a good practice to flush it distilled water) have to drain as much as you can from the system and fill with distilled water close all caps and run the system for couple minutes. Drain and refill with distilled water again and flush. After that drain the system and pour concentrate coolant (you already have water ) and measure the coolant with a tool to see what is the range of operable temperature. Drain some if needed and add some concentrate until the desired mixture is achieved.
Can you use Audi approved G40 Zerex 50/50 SI-OAT instead of G12? Can you mix them without draining the original fluid as I'm not sure how to tell what coolant is already in the vehicle. It is pink.... Thanks for the advice...
+Kerry Elkins Double check your owners manual or a Haynes manual. If you're absolutely unsure, you can contact an Audi shop or dealership for the correct info - but don't purchase the coolant they have on hand as it's most often marked up. Try to cross reference it with another brand found cheaper in most retail outlets

Does the drain nob have to be pulled put or something jut a bit when turned because I tried to do this on my a4 b7 and nothing came out ... top cap was off and everything so not sure what the problem was
Just tried doing it to my 04 a4 b6 Quattro and had the same thing happen. Was hopping someone would have a solution. Even took that big hose off to see if the plug was messed up but the hose itself was completely empty already even though the coolant tank was full yet. Weird. Have to track it down tomorrow to see what is going on.
I have an 08 A5. My coolant level on the tank would not stabilize and my heater still kept throwing cool air. The bubbles would just spill out of the tank. Anyone ?
Like an idiot I put oil in my coolant reservoir and I have been driving it like that for awhile. what im wondering is that after I do a flush on my system will there be damage from the oil at all or will it be fine
+Greg Kamra Ouch. I bet that was a harsh realization to come to. Well, I've never actually seen that happen before. Here's how I'd handle it. I'd thoroughly drain the system, then flush it through with some quality cooling system cleaner (no recommendations, unfortunately. Do a little research on this end), and then flush it. You may need to repeat the cleaning, can't hurt to do it a couple times. I'd then probably replace the thermostat as the oil/coolant mix could create a sludge which would keep it from working properly. I'd also look into replacing any of the coolant temp. sensors as they may not function correctly anymore either. Really sorry to hear this happened to you! It's such a bummer when you make that kind of mistake. But take solace in the fact that you're not the first to do it, and you definitely won't be the last haha Hope this helps you out. 1aauto.com?RUclips&CTA%20Comment&ATony 866-403-3393
My Audi A4 2007 has a intercooler system and I'm having the same problem it's no liquid coming out from that valve it's another way to drain all the water ?
+Noe Coutino The intercooler is part of the air intake system. It's job is to cool the filtered air that has passed through the turbocharger and is on it's way to the intake manifold. The intercooler does not have coolant or other fluids.
That's why they recommend leaving the vehicle on for 15 to 20 minutes so the cooling system can get rid of any air trapped in the system... leaving the heat on high and fan setting low allows the coolant to travel throughout the whole system thus ensuring the air bubbles get released through the top of the coolant tank
+Javier Rojas This procedure might be different for your application. We do not currently have a how-to video for this particular year, make and model. Thank you for asking! 1aau.to/m/Shop-1AAuto-c
Mine is low by a couple of inches from the "MIN" fill line. I have a long trip I need to take in a couple days. Can I just top it off? If so, where do I get the mix for it. Says G12 I believe? I can just get that from the dealership right? I don't think G12 coolant is sold at Autozone or Napa etc.
+Faze Pico Thanks for checking us out! We would recommend bringing the fluid back up to right under the max line to be safe when making long trips. If you cannot find this coolant in a local store the dealership will be able to assist with this. For this application in the video it is G12 fluid, yes.
Is this the same procedure for a cabriolet 1.8t? Usually I see quattros in the diy videos. I'm about to try this along with flushing my heater core. Also, the procedure is drain the radiator, place the cap on, refill the coolant, turn on the vehicle and keep the coolant level constant until there are no more bubbles and level is back to normal?

Aren't you SUPPOSED TO TURN YOUR CAR HEATER ALL THE WAY ON WHEN YOU START THE CAR AFTER REFILL???
What coolant is audi approved??
G12
G13 now. G12 no longer available or pentofrost.
Or Pentosin E
G13 is the current spec
what about the bleed valve behind the throttle body > Air trapped behind the waterpump and Thermostat.
That's why they recommend leaving the vehicle on for 15 to 20 minutes so the cooling system can get rid of any air trapped in the system... leaving the heat on high and fan setting low allows the coolant to travel throughout the whole system thus ensuring the air bubbles get released through the top of the coolant tank

it's the only way
That stupid drain plug doesn’t wanna close for me
Hi there my car appears to boil in expansion bottle.
most likely head gasket or warped or cracked head...compression leaking into your cooling system.Hope Im wrong.
