Where is it running from? Engine or Radiator areas?
If it is the radiator then it could be a cracked radiator, or the drain has been left open. You might have to replace the radiator if it is leaking from it at all.
If it is leaking from the engine the you could have a cracked block, or rusted out freeze plug, maybe a busted head gasket, water pump or even thermostat housing.
It may be best for you to take it to the shop and have it checked.

I have had this problem with my 98 aurora and have replaced all the same components. Temp gauge routinely shows 200 on highway (Fine) but in the city in stop and go will get to around 245. I installed a switch to manually turn on the cooling fans by connecting the ground to pin 86 in the relay for the fan(s). Otherwise the fans will not turn on to 245. This fix works but would like to know an actual solution.

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

There is a blockage or leak in your cooling system. That may come in a few different forms:
Incorrectly installed thermostat
Water pump not functioning - you may see water dripping from the pump or a stain from the hole under the water pump.
Severely coroded hoses/coolant passages - if the fluid is brown and the inside of the radiator rusty
External leak - you would see fluid on the ground
Internal leak - you would see steam/white smoke from the tail pipe or water in the oil (may look like chocolate milk or not), if the oil level is extremely high this would be a good indication
heater core bypassed

Probably not water pump. Engine is notourious for vapour lock.
Cooling system must be blead of air before thermostat will work. Cool bottom rad hose is a dead give away. If you are still watching this forum reply , and I will walk you through the only way I know how to make it work properly. It's actually easy if you do it my way. I have worked on lots of cars , and this engine was the hardest to bleed out. Did one Yesterday , and works perfect.
