SOURCE: where is the radiator drain plug on a 2000

Drain plug should be on the drivers side of the radiator, lower back (towards the engine) When placing the drain plug on place use some oil on the O ring to ensure a good seal when tightening it back in place. Good luck and keep me posted.

SOURCE: were is radiator drain plug on a 1993 cadillac

The textbook method is to remove the drain plug on the bottom of the radiator.

Most drain plug is make of inexpensive nylon/plastic and it may fall apart while you turn it.

The professional method is to loosen the lower radiator clamp and drop to lower radiator hose.

Drain the coolant onto a large drain pan and recycle the coolant


I just did a FREE write up on air purge from coolant system and how to detect initial state of blown head gasket at the Fixya tip selection.

SOURCE: 1996 cadillac sts overheating no apperant reason,

sounds like it could be one of the head gaskets. does coolant belch out if you hit the gas pedel like if you were going to pass someone on the hiway. if it does, exhaust gases are presurizing the cooling system beyond the max. presure of the cap...

Where and how do you get to the lower radiator hose on 99 Cadillac sts

Re: Where is the lower radiator hose?(99)
Stand in front of the car, open the hood, and face the engine.

On the left hand side of the radiator, at the top, is the upper radiator hose; which goes to the upper water pump connection.

On the right hand side of the radiator, from the bottom, is the lower radiator hose; which goes to the lower water pump connection.

Where is the lower radiator hose 99
It is a forum and goes on about draining the radiator.

Should the cooling system fluid be changed on a 2006 sts with 20,000 miles?

You should change you hoses about every 3 years. The heat from the engine wears down the rubber. When changing the hoses, that's when you change your coolant. Even with such low mileage, you should change the hoses and coolant. The radiator will drain when changing the hoses, best time. hope this helps

Lay under front of car and look under the radiator. The radiator support/header panel should have a hole in it look up in hole the petcock should be hiding in there. DO NOT LAY UNDER THE CAR WITHOUT THE E_BRAKE ON, please.
