THE INTAKE GASKETS ARE BAD. THE LEAK WILL SOON START INTERNALY AND YOU WILL NOTICE THE OIL WILL LOOK LIKE A BAD MILK SHAKE. REPLACING THE GASKETS REQUIRES TAKING THE INTAKE OFF THE ENGINE, REMOVING THE VALVE COVERS AND THE ROCKERS AND PUSH RODS. THE COOLENT LINES RUN THROUGH THE INTAKE SO THE COOLENT MUST BE DRAINED AND THE ALTERNATOR AND Power Steering PUMP HAVE BE LOOSENED SO YOU CAN GET THE VALVE COVER OFF. ALSO THE COIL PACK AND SOME OF THE EGR STUFF HAS TO COME OFF TOO. GET A CHILTON'S BOOK AND GOOD LUCK.
Check to see if there is coolant on the engine block. It is common for the Monte Carlos, along with other GM cars equipped with the 3400 V6 engine to experience leaking intake manifold gaskets. A leaking intake manifold will cause oil to leak into the coolant system and even worse, for coolant to leak into the oil system.
It's probably a head gasket problem.
The low coolant sensor is bad or disconnected.
thermostat gasket probably leaking. replace thermostat and gasket making sure that thermostat housing is flat.
I would suspect the manifold itself is leaking around the cooling passages. It will need to be removed and the gasket replaced.
Coolant leaking onto the floor of the passengers side or out drain tube for a rupture no heat for a blockage.
This is either the heater core leaking coolant or the air conditioning drain line is plugged. If the water tastes sweet on your tongue or is warm it is from the heater core.
Don't confuse engine coolant and air conditioning refrigerant. Engine coolant is Dex cool- Do not use any other kind as the sensors in the system will read differently with the wrong coolant and make incorrect adjustments in your system. Air conditioning refrigerant in your car is R-134a.
has the red coolant in a 2005 monte carlo been changed since reports on it deteriorating the head gasket?
Check your coolant level...
If coolant full could be a bad sensor
how to remove the engine of the 2001 monte carlo step by step
The coolant is below add in the coolant recovery tank. The engine would not overheat because only the recovery tank is low. It is also possible the low coolant sensor is bad.
See a dealer
Under the thermostat
A coolant flush on a 96 Z34 Chevy Monte Carlo helps greatly with increasing the efficiency of the cooling system. It removes buildup and contaminants from the system.
On a 2001 Monte Carlo it is located on the radiator just below the radiator cap.
I just had my intake gasket changed on my 99 Monte Carlo for the same thing. My cousin is a mechanic and has changed the same gasket on several cars with the 3.1 engine. The gasket is about $60 - $75 plus labor.
take it to a mechanic and get it repaired.
Its on the bottom of the coolant tank or inside the tank they cost like 50 or 60 bucks.
Look at the bottom or rear of radiator
approx 22 pints.
Radiator full and coolant recovery tank filled to mark Radiator full and coolant recovery tank filled to mark
It means it might need coolant, if not than you should probably see a mechanic.
