I have a cololant leak at the back of the motor any ideas? I have a 2000 A6 Quattro 2.7T with 82K. Please help

 

If its a slow leak, then its coming from the after run coolant pump under the intake manifold. Ultra common complaint on the 2.7T at around 80K. Not a cheap fix either.

 

Y eah I only notice it after I shut the car off and return to a puddle of fluid. I have a DIY with pics on how to do it I am going to attempt to do it myself I am pretty mechanically inclined so I hope it Pans out. Any suggestions?

 

I have a 2000 2.7 also. I had the auxillary water pump changed at the dealer for about $850. I alsohad $32 worth of O-rings installed around the back of the engine for coolant leaks at a cost of about $1100. Almost any coolant leak, other than a cracked Overflow resevior, is gonna cost you.

 

I went ahead and purchased a Aux. Pump and some gaskets. So I will be tackeling this next weekend. Thanx for all the help I will post again after I install and maybe even put some pictures for a DIY.

 

I too might have to go that route. What are the costs involved? Please post DIY info and pics upon completion.

 

i just replaced the hose to my heater core... it was leaking really bad i couldn't even get 30 miles on a full coolant tank without getting the low coolant warning

 

I changed my aux pump a fw months back. Pump was 125 I think and they chraged me 3 1/2 hours labor at $75/hr. Not bad.

I would get the NewSouth power gaskets and install them since you'll have the intake off anyway. They're only $75.

 

Audiphobic I will post a Diy with Pics upon completion. Hey formulagigi do the NewSouth Power Gaskets keep the heat down that much?

 

yes. and with these cars, every little bit help. It's only 75 bucks! here's info

Air Intake Power Gasket for VW and Audi
(NewSouth PN#: ) - Search By Car
[hr]





[blockquote]PowerGasket™ gives you up to 5% more power from your engine by reducing the temperature of the incoming air to your engine. NewSouth Performance has designed an insulating gasket that radically reduces the heat transfer from the cylinder head to the intake manifold. This gives you cooler, denser air for more horsepower and performance from your engine. Made from a high performance polymer, PowerGasket™ conducts on average less than 1/500th of the heat of the steel gasket that it replaces. Your intake manifold will stay 30-50° F cooler and your incoming air will stay 20-30° F cooler. PowerGasket Plus™ is a composite material that has a significantly higher continuous operating temperature than the original PowerGasket and does not require the application of any extra sealant.[/blockquote]

Audi 2.7T Power Gasket Set: NewSouth Performance, LLC has extended PowerGasket Plus™ line to include the Audi 2.7T V6 engines (APB code) for Audi A4 (2000-2002), S4 (2000) and Allroad (2001-2005) In real-time, side-by-side testing, a PowerGasket Plus-equipped Audi S4 drag car had 30°F lower intake air temperatures than its identical counterpart. Using a composite material that is specifically designed for gasket applications, the PowerGasket Plus™ gives you up to 5% more power from your engine by reducing the temperature of the incoming air to your engine with an insulating gasket that radically reduces the heat transfer from the cylinder head to the intake manifold. This gives you cooler, denser air for more horsepower and performance from your engine. Cooler air, denser air, means more oxygen. Your engine sensors register these changes and will inject more fuel to give you more power. Cooler air also reduces detonation, so you can turn up the boost or advance your engine timing for even more performance gains. PowerGasket™ has been designed for affordability, easy installation and no disruption to your manifold attachment and engine accessories. This means that you can simply swap your old intake manifold gasket for a PowerGasket. No buying longer bolts or installing multiple gaskets. In less than 2 hours, you will be enjoying a more powerful, better performing ride.
