I hate to say it but it may be your head gasket. Do you have a radiator leak down tester ? If you do you can do a compression leak down test by putting is on you rad. and then pump 2 pounds on the gauge and take off the coil or ignition wire and crank the car over and you have to have someone looking at the gauge and see if it moves up and down on the meter if it goes up or down any you may have to replace the headgaskets or a cracked head. I sure hope its not.

You may have a possible head gasket leaking.It's allowing air from the cylinder to pump into the cooling system. Have your cooling system pressure tested to confirm.

one normally fills the overflow tank not the rad and not with water, but with coolant. if filling the tank or rad - you must wait until the temperature has cooled down so that the coolant does not steam-off. If adding coolant and it is taking a lot -- that means what was in it has boiled off or leaked out. The coolant goes into the rad as well as into the engine block coolant galleries and water pump.

I had bubles coming from radiater,, i checked every think reparied radiater also ,,what is there are products in automobile shops which can repared the and work as engine sealeant in india

my guess is you mean the plastic RAD tank top leaks
leaks bubbes, are all leaks.
new RAD time, fixing a rad costs more than buying one new.
in fact buying one is cheaper because anyone can install it.
you can use bars leaks, magic sealant but why do that , why band aid a car, then have the top tank fail and blow the engine up, when overheated.
why do that?

I have a honda accord 1991 car is overheating engine light came on once and car doesnt overheat when i have the heater on do u think its a fan i changed the thermostat and flushed the radiator

The fan is electric. The fact that turning on the heater helps is a good indicator that the cooling system isn't sufficient but there are a lot of things to try.

The fan shouldn't come on very much, but it is easy to see if it is working OK. When the temperature gets above where it should be, open the hood and see if the fan is running. If it is, it is not the fan or the thermostatic fan switch. If it is not, the most likely cause is the fan-switch that is screwed into the bottom of the radiator. be carful when removing and replacing as the place they screw into the radiator may be plastic.

Assuming the fan does come on when the temperature is going up, the most likely cause is a radiator with poor flow,

be sure to check the simple things first. Is the coolant recovery tank at the proper level?

Are you loosing any coolant?

If coolant keeps disappearing, you either have a leak in the radiator or hoses or heater core or ... you have a bad head gasket or cracked head. A compression test will tell you if it is one these "bad" things, but do that last. A cooling system pressure test will tell you if you have a system leak, but not where it is. Do that after you check and do all the simple things, and if you are not losing any coolant, and the recovery tank is staying at the proper level, a leak is less likely. Sometimes with a blown head gasket, engine compression will force air into the cooling system. If that is what is going on, you should be able to open the coolant recovery tank when the engine is running but leave the hose that is connected to the lid down in the recovery tank coolant. Look for air bubles coming from the bottom of the hose or oil in the coolant recovery tank. If you see either of these, then head gasket or cracked head is likely.

If the fan is working and the coolant level in the recovery tank is staying where it should, the most likely cause is a plugged up radiator. Even flushing with a radiator flush may not help, and the radiator will likely need to be replaced. Replacing the radiator is not a very big job and after-market radiators are quite reasonable for a 91 civic from most autoparts stores or on-line, but if you haven't done one before, get someone to help you or at least get a repair manual.

When you flushed the radiator, did you bleed the cooling system? There is a bleed valve located near the front of the engine and toward the passenger side. It opens with a 10 mm. wrench. The valve is located at the top of the cooling system and it is to get all the trapped air out of the system after it has been opened or flushed. It helps to raise the front wheel on the passenger side, then open the valve and let all the air out. When you get a solid stream of antifreeze with no air, the system is bled.

The most important thing is don't just start replacing things. Find out what's wrong, then fix that. Otherwise you could spend a lot of money and still have the problem.

I hope it is something cheap and simple - it is more often than not.

Just replaced the water pump.Now i dont have any heat from floor or defrosters. any ideas?


The generic method of bleeding air from the cooling system is to use a floor jack and raise the front of the car as high as poss, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the cooling systeml

96 cadillac 32v over heating. thermostat is replaced and no water is leaking but after 30 mins it hot. no water in the oil.

this sounds like the rad is blocked up, if it was a head gasket it should boile up a lot sooner that that, you may need to have the rad flushed out or deskeled

Heater problems

Did you bleed the air oout of the cooling system - Their is a bleeding next to the therostat housing.

1 - When the vehicle is cold remove the rad(tank) cap and top up the level if needed

2 - start the vehicle with the rad cap off and leave the car run until you can see that the therostat has openned(look in tank/rad) to see fuild flow then open the bleeder slowly to let any air out of the cooling system. Once you have coolant flowing out of the bleeder close the bleeder and install the rad/tank cap.

NOTE - Be careful with the engine running and hot Coolant.

You make need to bleeding system 2-3 time to get all the all out. Once all the air is out of the system you problem should be solved. If air returns to the coolant system have the system checked for possible head gasket leaking air into the coolant system

2004 impala coolant level

The coolant container (called the overflow reservoir) will be marked as to what constitutes MIN and MAX levels that should be in it. If it's low, add coolant.

As for what temperature it should run at, the gauge on the dash is just a general indication, but usually it runs close to the middle of the gauge's range.
