It shouldn't be too difficult.

by the firewall. More room to work. Clamp off the hoses if you can and have a container ready to catch all the fluid when you remove the bottom hose from the reservoir. Don't overtighten the hose connected to the plastic reservoir. I replaced the stock clamps with some small hose clamps that you can tighten with a screw driver.

or buy one at Walmart for $1. Couple hoses and a sensor plug. You'd have to try to spend more than 15 minutes on it. Be careful with the coolant, though as it can eat through the paint if you spill any on the finish. Wash off any spills with a lot of water and you'll be fine. It's not like acid, it's just if it sits on there it can soften and screw the finish.

Be careful removing the small return hose. There is a plastic "T" that I broke when I replaced my reservoir.

I have replaced my Engine coolant reservoir my 2002 Audi A4 3.0 Quattro. And it seems that the coolant is coming up from the overflow out the Lid. Any ideas?
