Check These Kinds Of Things.

THERE ARE ALOT OF COMMON THINGS THAT CAN CAUSE COOLANT LOSS.
FOR EACH DIFFERENT THING THERE IS A DIFFERENT DIAGNOSTIC PROCEDURE.
BEFORE YOU PAY FOR SOMEONE TO LEARN ON YOUR CAR,I WOULD CALL A COUPLE OF GM DEALERS AND SEE IF THEY WILL LET YOU KNOW OF ANY COMMON FAULTS.RECALLS,TECHNICAL SERVICE BULLETINS.HERE IS SOME GENERAL INFORMATION FOR YOU.STEAM CAN ESCAPE ,IF IT IS MINOR AND YOU CAN NOT SEE IT LOWER THE WATER LEVEL.IF YOU SEE GREEN COLOR FLUID ,THAT IS A SIGN OF A LEAK,HOWEVER,SOMETIMES PEOPLE ADD SO MUCH WATER THAT IT LOOKS LIKE WATER.,AND IT ISNT GREEN ANYMORE.
THIS ONLY AGGRAVATES THE PROBLEM AS WATER BOILS AT 100C,COOLANT IS UNDER PRESSURE AND IS MUCH HIGHER.HERE ARE SOME THINGS THAT I CAN SUGGEST.coolant reservoir tank could be cracked,rad could be leaking,hoses,heater core in the car,radiator cap,if it a 3.8 litre,the head gaskets are common.did you ever see the temperature gauge go all the way up for say 30 sec,then come back down?head gaskets can do that.
get a pressure test done.if the pressure dissipates,there is a problem.

good luck

Dumbass.

1. That car comes from the factory with Dex-Cool and that is the required anti-freeze. The last time I checked Dex-Cool is ORANGE, so where is she going to find the green colored liquid.

2. Known for blown head gaskets? Ludicrous. If you had any clue you'd know they're known for leaking intake manifolds, usualyy in the 100k to 125k mile range. They crack around to EGR port.

How do you type with one arm patting yourself on the back all the time? You are the most dangerous of online diagnostic idiots because you truly THINK you know what you're talking about.

I would not rule out a blown head gasket on a GM 3800. My parents had one replaced on a 1996 Park Avenue they used to own (@ GM's expense) and according to their local Buick dealer, head gasket problems on 3800s for a couple or three year period in the mid 1990s were almost as common place as cracked intakes.

If it were my car, I would be asking some common sense type of questions then look for answere.

Question 1: Any ORANGE (similar in color to the Orange cleaners many people use to clean kitchens and bathrooms with) puddles on the floor near the radiator, under the engine. Most GMs built since the mid 1990s used an extended life antifreeze. If yes, then look to see where the water/antifreeze mix is coming from.

Question 2 - With the engine warming up, do you see evidence of leaks around radiator hoses and heater hoses? Sometimes, there will be a white colored crusty substance on the radiator near seams and hose connections which give evidence of a leak.

Question 3 - Is there orange fluid dripping from around the water pump. If so, the water pump shaft seals are worn and the pump is needing to be replaced.

If none of the obvious can be found, have the system pressure tested.

If the system does not hold pressure and no obvious problems can be found, then a compression test is in order to hunt for headgasket problems, and other more serious issues.

DEX COOL IS ORANGE,AND LOOKS LIKE ORANGE JUICE.ITS GOOD FOR 240000 KM OR 5 YEARS.THE 3.8 ALSO BLOWS HEAD GASKETS ALTHOUGH THE INTAKE IS MORE COMMON.SOME PEOPLE HAVE HAD PROBLEMS WITH DEX COOL,WHAT EVER COLOR IT IS,WHEN IT LEAKS IT IS NOT WATER.SOME PEOPLE HAVE ACTUALLY PUT GREEN COOLANT BACK IN ONCE THE WARRANTY IS EXPIRED..EVEN THOUGH THE ORANGE JUICE IS FROM THE FACTORY,YOU CAN RUN THE GREEN,IT JUST HAS TO BE CHANGED EVERY 2 YEARS.AND AS FAR AS THE GASKETS GO,I DO NOT KNOW WHERE YOU GET YOUR INFO FROM,BUT MY NEIGHBOR IS A SERVICE MANAGER AT A GM DEALER,AND THE HEAD GASKETS DO GO,OFTEN.EVEN THE 240 HP SERIES 2 IS ONLY 240 HP. KEEP IN MIND THAT 400+ HORSEPOWER ENGINES RAN GREEN COOLANT FOR YEARS.HMMMM

Can't see for all the flames...Check for water or coolant in the oil, it will look white or milky, if this is the case you probably have a bad head gasket. I appologize for the rantings of the stressed out individuals here, they have problems.

everything i say is counterindicated by "his royal highness".but lets be realistic here,if the person checks their coolant reservoir,and there is orange fluid in there,then look for orange.if its green,look for green.BUT HEY DID ANYONE THINK THAT MAYBE THE COOLANT RESERVOIR HAS A HAIRLINE CRACK IN IT ?
