I drive a Camry V6 3.0L Every time I top up the coolant to the recommended level and after driving the contents in the reservoir boil over and spill out.


There may be a slight head gasket leak to the coolant jacket, not large enough to overheat the engine. It is normal for some coolant to escape at operating temp, but not lots, and it should cool down to about the recommended level again.

Something is pressurising the coolant jacket. Have it tested for the presence of combustion gasses in the coolant. This is a simple test.

Another thing, that model often develops a crack in the radiator plastic top tank. It is not the problem here, but worth knowing.

Tip

Vehicle overheating tips


If your vehicle engine coolant temperature gauge indicates overheating, if you experience a loss of power,or if you hear a loud knocking or pinging noise, the engine has probably overheated. You should follow this procedure............

Pull safe off the road, stop the vehicle and turn on our emergency flasher. Put the transmission in "P" (automatic) or neutral (manual) and apply the parking brake. Turn off the air conditioning if it is being used.

If coolant or steam is boiling out of the radiator or reservoir, stop the engine. Wait until the steam subsides before opening the hood. If there is no coolant boiling over the steam, leave the engine running. CAUTION: To avoid personal injury, keep the hood closed until there is not steam. Escaping steam or coolant is a sign of very hing pressure.

Visually check to see if the engine drive belt (fan belt) is broken or loose. Lock for obvious coolant leaks from the radiator, hoses, and under the vehicle. However, note that water draining from the air conditioning is normal if it has been used. CAUTION: When the engine is running, keep hands and clothing away from the moving fan engine drive belt.

If the engine drive belt is broken or the coolant is leaking, stop the engine immediately and call your mechanic of assistance.

If the engine drive belt is okay and there are no obvious leaks, you may help the engine cool down more quickly by running it at about 1500 rpm for a few minutes with the accelerator pedal lightly depressed.

Check the coolant reservoir. If it is dry, add coolant to the reservoir while the engine is running. Fill it about half full. CAUTION:Do not attempt to remove the radiator cap when the radiator are hot. Serious injury could result from scalding hot fluid and steam blown out under pressure.

After the engine coolant temperature has cooled to normal, again check the coolant level in the reservoir. If necessary, bring it up to half full again. Serious coolant loos indicates a leak in the system. You should have it checked as soon as possible at your mechanic's workshop.

Good luck.

Loses water from resevoir but not from radiator


So the level keeps dropping in the reservoir? If you have to keep adding coolant to the reservoir, the system is leaking or losing coolant somewhere. Have the system pressure tested to find the leak. Is the reservoir itself leaking? When the level gets low enough, first the reservoir will go dry, then the radiator level will start to drop.
Here's how the reservoir works: coolant is under pressure from the radiator cap seal. As coolant heats up from hot engine, it expands, and pressure forces the radiator cap seal up, coolant is forced into the reservoir-remember the hot mark on the reservoir? When car is shut off, coolant contracts, creating a vacuum in top of radiator. This vacuum works to suction coolant back from reservoir into the radiator, keeping the radiator topped up, and coolant should now be at the lower cold mark on the reservoir. It is a closed, sealed system. The only loss of coolant will be a very small amount of evaporation from the reservoir. If coolant level keeps dropping, there is a leak somewhere.

Engine is too hot, water circulation n radiator okay.


Check the coolant reservoir tank and fill if needed. Most modern cars have a plastic reservoir of coolant connected to the top of the radiator. This will allow you to see if your coolant is low. Many have marks indicating the proper level of coolant when the engine is hot. Check to see if the coolant is at that level.
Add coolant (or water, in a pinch) to your reservoir to the full/hot line. On most cars, you can add liquid to your reservoir even if the car is hot. Check the owner's manual to be sure, or wait for the car to cool before opening.
If your car only has a radiator and no coolant reservoir, you must wait for it to cool before checking the level of coolant.

Temperture gage starting to fluxuate while driving.


This can be caused by an insufficient coolant (aka antifreeze) level. Look at the coolant level in the reservoir under the hood. There should be two marks on the bottle "warm" or "hot" and "cool" or "cold". If the engine has been running for a while as in the case when the car has been driven few miles, the coolant level should be up to the "warm" or "hot" line on the bottle. If the car has been parked without the engine running for a couple of hours or more, the coolant level should be at the "cool" or "cold" line on the bottle.

Never remove the radiator cap when hot or if the engine has only been been stopped for less than 2 or 3 hours.

If the hot coolant is at a level that is below the warm or hot line, you should add more of the coolant / water mixture only to the reservoir - not to the radiator. If you are only able to check the coolant level when it is hot - you will have to repeat this procedure until the coolant level of the reservoir is maintained. Checking the hot coolant level can only be done when it has been allowed to cool between hot checks. The cooling period is the only time when coolant is drawn from the reservoir back into the radiator.

If the cold coolant is at a level below the cool or cold line of the reservoir you should add more of the coolant / water mixture to the reservoir and to the radiator, too. Fill the radiator to the top of the neck where the tube from the reservoir connects to it.

If you're still having widely fluctuating temperatures while driving at normal operating speeds, there may be a problem with the water pump, thermostat or other portion of the cooling system.

I hope this helps & good luck!

My sunfire overheats and leaks out overflow everytime i drivee it.i changed water pump,thermostat the fan is working fine and had a water pressure test done last mth


DID YOU BLEED AIR OUT THE COOLANT SYSTEM.TO BLEED COOLANT SYSTEM, FILL THE COOLANT SYSTEM THROUGH THE RESERVOIR TANK OR THE RADIATOR UNTIL THE FULL COLD MARK IS REACHED.BESURE TO USE 50/50 HALF WATER AND ANTIFREEZE.YOU CAN BUY ANTIFREEZE THAT IS ALREADY PREMIX 50/50.AFTER ADDING ANTIFREEZE TO RESERVOIR OR RADIATOR FILL RADIATOR TO FULL MARK OR IF YOU DONT HAVE RADIATOR CAP ON RADIATOR POUR ANTIFREEZE IN THE OVERFLOW JUG UNTIL COOLANT LEVEL STAY THE FULL COLD MARK.WAIT AWHILE UNTIL COOLANT LEVEL STOP DROPPING.NOW INSTALL THE RADIATOR OR OVER FLOW JUG CAP.START THE ENGINE AND ALLOW IT TO RUN UNTIL NORMAL OPERATING TEMPERATURE IS REACHED AND THE UPPER RADIATOR HOSE BECOME HOT.STOP THE ENGINE AND OBSERVE THE COOLANT LEVEL IN THE OVERFLOW JUG. THE COOLANT LEVEL SHOULD BE AT THE FULL HOT LINE.ALLOW THE ENGINE TO COOL UNTIL THE AMBIENT TEMPERATURE IS REACHED THEN CHECK THE COOLANT LEVEL IT SHOULD BE AT OR ABOVE THE FULL COLD LINE.ADD MORE COOLANT IF NECESSARY. WARNING BECAREFUL WHEN OPEN THE RADIATOR CAP OR JUG OVER FLOW CAP.USE A LARGE RAG OVER THE RADIATOR CAP TO KEEP FROM GETTING SCALDED.OPEN RADIATOR CAP A LITTLE AT A TIME TO KEEP FROM GETTING SCALDED.WAIT UNTIL ENGINE COOL DOWN BEFORE OPENING RADIATOR CAP OR OVERFLOW JUG CAP.WEAR SAFETY GLASSES.

Coolant reservoir is overfulling after being driven


It probably got overfilled at some point. There's a max line on the reservoir that you shouldn't fill it over. Coolant expands as it heats up so if there's too much in the system, it's normal for it to overflow.

My engine is overheating, and when i lift the hood it appears that the coolant in my coolant reservoir is boiling/bubbling....there doesnt seem to be a leak except from the reservoir itself, the reservoir...


With the engine cool open radiator cap. If the level is low you are losing coolant. Go for a 30/40 dollars, radiator compression test. Might be a bad radiator cap seal, water pump leak cylinder head gasket.
If the coolant level is in top, then there are many other reason.

Have new radiator, water pump hoses, belts; system has been bled; experimented with bypassing the heater core; thermostat removed...car still overheats. Also, coolant goes to the overflow bottle, but often...


The reservoir,and,or,the tubing from the radiator,to the reservoir may have a pin hole in it,or the tubing is sucking together.Replace the tubing,and the radiator cap,and the reservoir top.See if it will work correctly.Fill reservoir,and radiator,and let it run until the cooling fans cut on,then cut the engine off.Wait about 25 minutes,and see if the reservoir will drop in level,if so,repeat this process until the vehicles cooling system is normal.Make sure the cooling fans are coming on,and going off,with the ac off.If the cooling fans are coming on,then that is good,but,they must go off by them selves,or the cooling system is not cooling down.

Car running hot. Need to check coolant level. manual says there is a see-thru reservoir but I can't locate it.


find the radiator cap, there is a small hose attached to it, now follow that hose, it ends at the reservoir, thats you are looking for. you need to check the radiator level, but only take the cap off when its cool. it you have to add any coolant, find out why. overheating is the number 1 killer of cars.
