Audi A6 2001 quattro 2.8 mysterious over heating

You buy a complete kit

That includes the water pump,timing belt,all
idler pulley's ,so you don't have to go back
there when the water pump fails

Just like you replace brake hardware, sometimes,
as it rusts,wears & heat cycles

You do your belt at 140,000 km (84,000 miles) about
every 7 years (12,000 per year)

On the side of the transmission.

The thermostat is located in front of the engine, between V cylinder banks, for Audi A8 V8 4.2 Quattro Automatic. See pictures below:




Remove the thermostat housing (2 bolts) and the old thermostat. Note the orientation of the old thermostat (vent valve facing UP). Clean both thermostat housing and block surfaces and remove all traces of old gasket material. Install the new thermostat vent valve facing UP.

Please do rate my response. Thanks!

Hi I also have an Audi Auto 2.8 non quottro had a simler problom and it turneed out to be one of the gear relays that are under the stering wheel on a left ****** that is.

Check out these 2 websites, eautorepair and alldata, you register your car and pay for access to manual info for a time period u set (eautorepair 1week to 1 year, $11.99- $29.99, u can print any info off your computer). Let me know if u can't find your vehicles info.

It's the wheel bearing. Guaranteed. Just replaced mine. Go to Audiworld tech articles for step by step instructions on how to test the wheel bearings. They must have been put in wrong last time or they just went out again.

Hi Counchcharles
Your service displays have to be reset with the correct electronic equipment....When you chage the engine oil the computer management system will have to be told...thats the job of the scanner....go to a service centre and have them cancel it for you.
The over heating problem is nothing to do with that though.....Check to see if you have any leakage....open the pressure cap only when the engine is cold....best is first thing before start up in the morning....check to see if you need topping up....if you do, it'll mean you have a leakage....Check the entire radiator and hoses where they go from the rad into the engine and ventilation system for stains from the coolant....If you can't find any look at the thermostat....If you remove it, replace with anew unit, do not dis-guard it also check the pressure cap and if needs be replace....Good luck

replace the coil pack, sounds like it is over heating.
