Where is the catalytic converter located on a 99 volvo s80? How easy is it to replace?

SOURCE: Location of thermostat and replacement

Finding the thermostat is easy. Just follow the top radiator hose back to the engine.
The question I have is how to get to the bottom screw of the thermostat housing.

Any Sugustions anyone?

SOURCE: 99 Volvo S80 water pump replacement

if this helps.. I had the 1998 model S70. the water pump was driven by the timing belt. you had to take the timing belt off just to replace the water pump. it was just a simple bolt on replacement. the only difficult issue is resetting the hydraulic tensioner on the timing belt. the hydraulic tensioner has to be completely taken off and compressed VERY SLOWLY in a vise. then insert a very hard drill bit or (special volvo tool) into a keeper hole, reinstall hydraulic tensioner onto car and reinstall timing belt.very quickly remove drill bit from keeper hole in tensioner and the tensioner snaps back out to put tension on belt. and you are done.

SOURCE: 2000 VOLVO S80 HAS A LARGE VACUUM LEAK. HOW DO I

In the past we have used starting fluid to find vacuum leaks. Start the engine, let it idle. Spray quick shots of starting fluid at your vacuum lines in isolated areas. When the starting fluid find the vacuum leak the engine will react to it... usually by going up in rpm. Depending on your engine computer, it may stall the engine. Either way you will find your vacuum leak. Get starting fluid or "ether" at Autozone or O'Reilly.
