Where is temp sensor on my olds Aurora, 1998?

SOURCE: 1998 olds Aurora i have an oil leak, is it common

There are common places, you'll just have to look around to see where the leak is:
Around the oil filter and the housing
Around the oil pan and the pan gasket
The oil seal behind the damper pulley
Valve cover gaskets
These are the most common places, leaks can spring up anywhere.

You can buy a replacement ambient air temp sensor at an auto parts store for about $10. Its as simple to change as a light bulb and can be found behind your front bumper at the base of the radiator.

If this is for the water temp, then open your hood. Standing in front of the car, look down at the radiator, and follow the top hose to the engine. It will take you to where the Thermostat housing. On the housing, you will see the wiring for the temp sending unit.
