A 91 should have regular green coolant. Make sure to read the label on the bottle. Sometimes it is premixed and some times you need to mix it yourself. If you have to mix it your self you will use 1/2 coolant and 1/2 water.

You can add it directly into the radiator through the radiator cap. Make sure the engine is cold before you remove the radiator cap!. Once the radiator is full you can top off the overflow container. It should be on the passenger side of the car near the battery. It will be the white bottle with a black hose going into it.

Do not mistake this with the washer bottle. The washer bottle will have the blue cap.

Why did my 2011 DTS Cadillac overheat?


An overheated engine can be caused by anything that decreases the cooling system's ability to absorb, transport and dissipate heat; therefore engines can overheat for a variety of reasons. Let's take a look at some of the most common causes.
Cooling System Leaks
This is the primary cause of engine overheating. Possible leak points include hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs, automatic transmission oil cooler, cylinder heads and block. Perform a pressure test. A leak-free system should hold pressure for at least one minute.
Wrong Coolant Concentration
Be sure to use the coolant recommended by your vehicle's manufacturer. The wrong type of coolant and/or mixing the incorrect concentration of coolant and distilled water can also result in engine overheating. The best bet is to perform a complete flush and fill.
Bad Thermostat
A thermostat is a heat-sensitive valve that opens and closes in response to engine temperature. Heated engine coolant passes through to the radiator when the thermostat is in the open position. In the closed position, it prevents the flow of coolant to speed up the warming of a cold engine. When the thermostat gets stuck in the closed position, coolant stays in the engine and quickly becomes overheated, resulting in engine overheating.
Blocked Coolant Passageways
Rust, dirt and sediment can all block or greatly impede the flow of coolant through the cooling system. This can limit the system's ability to control engine temperature, which may result in higher operating temperatures and engine overheating. Once again, a flush and fill is recommended to remove debris.
Faulty Radiator
By passing through a series of tubes and fins, coolant temperature is reduced in the radiator. Leaks and clogging are some of the most common causes of radiator failure. Any disruption in the radiator's function can lead to elevated engine temperature and overheating.
Worn/Burst Hoses
A hose that contains visual cracks or holes, or has burst will result in leaks and disrupt the flow of engine coolant. This can result in overheating.
Bad Radiator Fan
A fan blows air across the radiator fins to assist in reducing the temperature of the coolant. A fan that wobbles, spins freely when the engine is off, or has broken shrouds will not be able to reduce the temperature to proper level, thus possibly resulting in engine overheating.
Loose or Broken Belt
A belt is often the driving link that turns the water pump at the correct speed for proper coolant flow through the cooling system. If a belt is loose or broken, it cannot maintain the proper speed, thus resulting in poor coolant flow and ultimately, engine overheating.
Faulty Water Pump
Known as the 'heart' of the cooling system, the water pump is responsible for pressurizing and propelling engine coolant through the cooling system. Any malfunction of the water pump, including eroded impeller vanes, seepage or wobble in the pump shaft, can prevent adequate coolant flow and result in engine overheating.

Overheating car


maybe you have a blown head gasket your leaking head gasket when ur car is cold open your radiator cap see if the coolant in it try to tap up coolant until the neck of your radiator then start your engine and observe the radiator neck if the collant puks it out if your coolant is pukking out meaning you have a leak or blown head gasket and thats the cuz of your overheating

Overheating


OVERHEATING CAN BE CAUSE BY MANY THINGS LIKE FAULTY THERMOSTAT AND FAULTY RADIATOR PRESSURE CAP,TOO MUCH WATER IN COOLANT SYSTEM NEED 50 / 50 WATER AND ANTIFREEZE.LOOK FOR WATER PUMP WEEP HOLE LEAK, IF COOLANT LEAKING OUT WEEP HOLE WATER PUMP BAD NEED REPLACING.CHECK FOR LOW COOLANT LEVEL, YOUR RADIATOR OVERFLOW JUG SHOULD HAVE COOLANT AT THE FULL COLD MARK IF NOT KEEP ADDING COOLANT INTO COOLANT OVERFLOW JUG UNTIL COOLANT STOP DROPPING AND FULL COLD MARK, IF OVERFLOW COOLANT JUG WAS EMPTY RADIATOR IS LOW ON COOLANT.WHICH CAUSE AIR IN COOLANT SYSTEM KEEPING THE ENGINE COOLANT TEMPERATURE SENSOR FROM BEING SUBMERGE IN HOT COOLANT WHICH TURN ON THE COOLANT FANS.WHEN ENGINE COOLANT TEMPERATURE GET CERTAIN SET TEMPERATURE LIKE 190 DEGREES THE PCM AND COOLANT SENSOR WILL TURN ON COOLANT FANS, IF VECHICLE OVERHEATING COOLANT FANS NOT WORKING EITHER YOU HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR CHECK COOLANT FANS FUSE AND RELAYS. YOU CAN CODE SCAN CAR TO SEE IF YOU HAVE FAULTY PCM, FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR FAULTY COOLANT FAN RELAY.IF COOLANT FAN AND ENGINE COOLANT TEMPERATURE SENSOR OKAY,YOU HAVE CORRECT COOLANT LEVEL IN COOLANT SYSTEM, THERMOSTAT AND RADIATOR PRESSURE CAP BEEN REPLACED, YOU COULD HAVE BLOWN HEAD GASKET CHECK ENGINE OIL LOOKS LIKE MILK SHAKE HEAD GASKET BLOWED ALSO WHEN HEAD GASKET BLOWED YOU CAN DRIVE CAR SHORT DISTANCE START OVERHEATING AND YOU LOOSE ENGINE POWER SUSPECT BLOWED HEAD GASKET.

CAR OVERHEATING FIRST CHECK FOR LOW COOLANT IN THE RADIATOR COOLANT OVERFLOW JUG.IF COOLANT LEVEL IN OVERFLOW JUG LOW REFILL ADD COOLANT BACK TO THE FULL COLD MARK.PUT RADAITOR CAP ON COOLANT OVERFLOW JUG START ENGINE LET IT IDLE UNTIL IT OPERATING TEMPERATURE.MAKE SURE TOP RADIATOR HOSE GETTING HOT WHILE ENGINE WARM UP.IF TOP RADIATOR HOSE DONT GET HOT WHILE ENGINE IDLING YOUR THERMOSTAT COULD BE STUCK CLOSE CAUSING CAR TO OVERHEAT.IF TOP HOSE IS GETTING HOT.CHECK FOR COOLANT LEAKS CHECK TOP RADIATOR HOSE AND BOTTOM RADIATOR HOSE FOR LEAKS.CHECK FOR LEAKS AT THE RADIATOR CORES AND PLASTIC SIDE CONTAINERS.IF ALL IS GOOD ENGINE OVERHEATING WHILE IN A LONG TRAFFIC LINE, COOLANT FANS NOT COMING ON.COULD HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR BLOWN COOLING FAN FUSE OR RELAY.COULD HAVE PCM FAULT.MAKE COOLING FAN ELECTRICAL CONNECTORS AND WIRING NOT DAMAGE OR BROKEN.

MY 2001 CHRYSLER LHS IS OVERHEATING. THERE IS NO VISUAL LEAKAGE. I PUT WATER IN IT AND IT DID NOT RUN HOT, HOWEVER, AFTER PUTTING WATER AND COOLANT, AFTER 10 MINUTES OF DRIVING, IT RAN HOT. WHAT CAN...


1. The thermostat in the cooling system could be sticking and need replacing. If it sticks in the closed position coolant cannot flow to and from the radiator and the coolant circulating through the engine will quickly overheat.

2. The water pump may be on its last legs and require replacing. If the pump has failed (and they do) the coolant will not circulate through the engine and radiator as it is designed to do and it will overheat quite quickly.

3. There could be a build up of debris in the cooling system that is impairing coolant flow through the engine. This can occur if the cooling system is not fully flushed out every 2 years and the coolant replaced. The cooling system must then be bled to remove all air. When replacing the coolant you MUST use the correct product as specified by the manufacturer and in the correct mix.

4. Radiator caps must be sound (and the correct specification) to ensure coolant does not escape and result in a low coolant condition and then overheating.

You need to get your car to a competent mechanic quickly to check and rectify the problem. (You may find it is only the thermostat as this is a common problem with time and usage.) Driving your car with an overheating condition WILL result in expensive engine damage. The head gaskets will blow and the heads on the engine will crack. Additional engine damage is also possible.

Cooling systems must be well maintained to prevent overheating and consequential engine damage.

Where do you put engine coolant? I think mechanic


If the car is overheating it is not just cause the coolant is low. There is a leak somewhere in the system this must be fixed first.

Overheating,smoking and dying.now it ont start at


What is overheating ? Engine or tranny? You said you put tranny fluid in, but not in the engine right? Engine sounds like it is toast. Is there any abnormal look to the engine oil on the dipstick? Are you losing coolant?
If you add coolant with engine NOT hot, and watch the radiator fill spout with engine started and warming up, do you see water gurgling?
Do a compression test.
