    Hi Mark Burdette, I want to help you with your question, but I need more information from you. Can you please add details in the comment box? You say ON your car... I suspect you mean IN. Where is it leaking from? Can you see where at all?

1. Look for where it is leaking from.
2. If the leak is not visible or is very slow try a radiator stop leak fluid.
3. Otherwise replace seal, hose, or whatever is leaking.

SOURCE: I Have a 1997 cadillac sts over heating problem

The most common overheating problem with the Northstar engine is a blocked purge line(small hose).The purge line is designed to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank (not the cap) ,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.
If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.
The hose goes in to the engine to a crossover and comes out the other side close to the thermostat housing,the blockage may be there.

2008 Cadillac STS with 4.6l V8 Northstar engine. Do I need to add the anti-leak tablets to the new coolant or is this newer model engine exempt from that requirement?

You have some protection for the aluminum components with new coolant but for all engines with aluminum pieces,the tablets are cheap insurance and recommended to prevent/reduce electrolysis which results in leaks.
Use them.

Location on 2008 Cadillac sts for the crankshaft sensor

Here is the sensor location on the 2005 STS. My understanding is that on the 2005 it sat over the exhaust cam sprocket and on the 2006 it sits over the intake cam sprocket. That should be no problem as there will only be one to locate on your 2008.

Car won't start

Sounds like it is burning coolant, possible blown head gasket or cracked head or intake leak.

If too much coolant enters the cylinder it will stop the engine from running.
