I WILL TELL YOU TO REMOVE THE RADIATOR AND BRING IT TO A RADIATOR SHOP TO MAKE AN HYDRO TEST ON IT THEN YOU WILL KNOW WHERE IT LEAKS

I had mine pressure tested without removing it.

A bad radiator is a radiator that is leaking or clogged. If you are loosing coolant then you have a leak that should be easy to find if the leak is at the radiator. If it is clogged your engine will overheat.

Find where the fluid is coming out and repair/replace it.

If your radiator is leaking then you will need to replace it. Additionally, if you find that your car is constantly running hot you will need a new radiator.

The only way to find out is to have a look it could be anything.

If you cannot find the drain plug you can also pull the lower radiator hose. MAKE SURE THE ENGINE IS COLD!!!

It could be water pump, leaky radiator, hoses, head gasket, or just about anywhere else that the coolant circulates. You'll need to get under and find out where it's leaking.

If your coolant is leaking, chances you have the head bolts pulling, a common problem on northstar engines. Dealer head bolt inserts don't work, they will tell you that, and no guarantee. The only 100% success rate fix would be " NS300L ". These are longer head bolts and inserts. You can find them on the web, and on Ebay.

easiest way is to fill radiator and look and see where fluid is coming out, but Im sure you thought of that. The best way is to plug the ends of the radiator up with some type of rubber stopper then insert blow air through the drainport while holding it under water. Wherever the bubbles are coming from is where its leaking.

First, you must find out WHERE it's leaking. If it's a radiator hose or heater hose, replace the hose. If it's a water pump leak, replace the water pump. If it's a leaking radiator, take it to a radiator shop and have the radiator replaced or repaired. If it's a freeze plug, head gasket or other leak, you'll need more serious repairs.

You need to determine exactly where the coolant is leaking from before you can make repairs. Use a small mirror and a good flashlight and probe around until you find it.

Try to find out where it's coming from. Often coolant will leak down the front of the water pump, under the pulley. Even if you don't see the coolant, look for the mineral trace of the water. By the time you notice a leaky water pump it has usually been leaking for a while and has left a noticeable trail. If you don't notice coolant leaking there, check other places, freeze plugs, the sides of the radiator, radiator and heater hoses... Again, the coolant and water minerals typically leave a nice bright trace to tell you where it's leaking. If the radiator is leaking, don't try to fix it yourself and certainly don't put stop leak or any other chemicals in it. Either replace the radiator or take it to a radiator shop and have THEM repair it properly.

Where is it leaking? That pressure test sounds funny, why would you pressurize only the pump and radiator? If you are leaking coolant outside the engine, locate the source. If you are losing it from the radiator but cannot find a puddle suspect a head gasket problem. Check the Radiator cap first, if it is bad high pressure coolant will travel back to the overflow bottle.

Im trying to find this out also, i have a 99 deville and I purchased a set of 24s to put on it. I need to find this out so i can lift it.

There is a top radiator hose that runs parallel to the radiator. About six inches below the top hose is another hose that connects from the lower back right area of the radiator to the housing of the water pump. Where the hose connects to the water pump housing is where you'll find the thermostat on a '98 Deville.

assuming you have no water in the radiator. there can be several causes for this. one is the radiator has a hole, the water pump bushing is bad and leaking, you have a cracked block or head, or you have a blown or rusted through freeze plug, or your heater core could be leaking as well. or a hose has a hole in it. fill it up and see if you can find any leaks. if there is water in the radiator. it can be a bad thermostat, bad water pump, cracked head or blown head gasket.

You will find that it is located on the bottom of the radiator. If you do not find a drain Petcock on the bottom of the radiator you must remove the lower radiator hose in order to drain the radiator.

Coolant reservoir, or directly in the radiator. If you are having to add much coolant, you need to find out why. Serious engine damage can occur if it is leaking inside the engine.
