engine overheating

Hello,

It sounds like you have a coolant leak here is a guide that will walk you through the repair

Please run down this guide and report back.

Is the heater core expensive? Im on a tight budget at the moment. So a heater core will leak on the drivers side?

Actually, the heater core is on the passenger side. Coolant normally leaks into the drain pan for the water that condenses when the air conditioning system removes the humidity from the air, but it depends on how the system was designed. I suspect pressure in the cooling system is causing that hot coolant to spray over to the driver's side.

Heater cores are not outrageously expensive but the labor to replace them is. On most Ford products the steering column must be lowered and the dash must be pulled back to remove the heater box and actuators. The air conditioning hoses must be disconnected so that means recovering the refrigerant, then evacuating the system and recharging it. Thanks to your politicians and the EPA, air conditioning work is also expensive.

As a temporary measure you could disconnect the two heater hoses at the firewall, then buy a plastic fitting to connect them together. That will bypass the leak and it should stop the overheating. Keep in mind though that obviously you won't get hot air from the heater, but you won't get it from the defroster either. The air conditioner will still run in defrost most, like normal, to remove the humidity from the air so it won't condense on the cold windshield and cause fogging, but since the air will be cold, it will take longer to defog the windshield. If the other guy runs a red light and causes a crash, his lawyer and insurance investigator will look for things like that to try to shift some of the blame to you. That rarely happens, but I wouldn't be doing my job if I didn't at least mention it.

Could I put the fitting on myself? And is the firewall easy to get to?

Could it be the water pump?

Sorry that I dropped the ball and failed to reply sooner. Have you solved the problem?

I have replaced all aspects of cooling water pump, fan thermostat and reservoir still states hot after driving a short distance also have bleed system . once it registers hot pull over turn off for ten to fifteen minutes then it is fine. what gives?

Hello,

Is sounds like you may have a blown head gasket, please follow this guide to confirm

My 2001 Lincoln overheats very quickly, I can see water boiling in the engine coolant compartment. The water from the compartment get so hot that it starts leaking from the top of the cap. The car also turns of after being in park for a couple of minutes and it also turns off when Im waiting at a stop light. Can you please help?

Check the thermostat and water pump operation if okay get it block and pressure tested

Car runs fine and operates normally without overheating until I turn on the A/C. If I disconnect the wiring plug on the compressor all is fine, but if reconnect it car immediately starts to overheat. Could the clutch be seized causing excessive load on the engine? What is the solution? Can I replace only the clutch to prevent having to recharge?

first see if your cooling fans are working on radiator. when you turn on A/C at least one should work. then check fuses under hood fuse box there are relays there as well if fuse is good then check relays.

Okay will do, but would the car overheat in hot summer temperatures if fans were not working? I have had this problem all last summer so I kept the compressor unplugged. I had no AC, but normal engine temperature at all times.

normally there are two fans one comes on when A/C is turned on the other may have failed. If a mechanical fan the shroud around radiator is important as it will not direct air through radiator if not there. also, it can be a radiator problem or something else but you need to start.

Perfect. Will start there. Thanks!

Please let us know what happens.

Cheers, Ken

I have a 2004 Lincoln LS and I'm having the same problem as lemon cycle, the overheating and the fan not coming on. How do I find the fan senor attached to the engine? Then how to I check it to make sure it has malfunctioned.?

The radiator housing has been replaced and so has the upper radiator hose. I took it in for code reading and it only gave throttle problems which may have been caused when I removed the clamp

Have you checked the relay and the sending unit?

I'm not sure what those things are. I did check the 60 amp fuse and it was good, I then removed what I thought my be the fuse in the engine compartment by swapping with another fuse and that worked also.

My car is over heating so i took it in to a mechanic he said it was the heater control valve. I got that fixed and then my battery went dead, couldnt turn on the car after part was replaced. So I got a new battery and now my car is still overheating. It has a gurgling sound coming from the coolant reservoir. But there is plenty of coolant.

Got any ideas?

ensure radiator fan(s) are coming on properly , if so the thermostat needs removed and tested

also look into having the system bled of air, they can be tricky

my car started overheating last week so i replaced the thermostat, when it started overheating i turned the car heater all the way to high it helped at the beginning but not anymore. now the gauge goes all the way up.

have your coolant system pressure checked for a head gasket problem.

My engine is overheating and I would like to know the possible solution(s). Radiator has fluid but engine begins overheating after running for 10 minutes. If the thermostat is the possible problem how do I check and how do I change it???

Try the thermostat 1st - you must first take the cover off of the motor. Then with a 5/16 socket take the entire ac tubing off starting from the intake on the upper left hand corner of the motor. Then right up under the container labeled torque remove the screws with the 5/16 socket and a 3/4 extension be careful not to stripp the screws. If water start to drain a little thats okay. You should hear a little air escape due to the pressure coming off of the thermostat.

my linciln ls is overheating mainly when i turn the ac on, i replace the hyl fan/motor and also the themostat and still overheating, the hose also have pressure on it and i have not change out the cooling sensor(dont know where it is)

Do you see the fluid circulating in the reservoiron the passenger sde? If you dont then you could have a faulty actuator. The actuator is located on the side of the cooling pump on the the passenger side. It looks like the power steering pump since you have 2 of them. The one on the drivers side is for the steering. Remove the actuator and try mnually applying power and see if it responds? If it does not then the actuator is no good.

car overheating already changed thermostad a mechanic that works for ford told me that it was something to do with something hydrolic controls the fans

Very well could be, could be the fan, pump, or the actuator on the pump

Car is overheating and when I put water in the reserve it runs out pretty fast. It does not look like it is coming from the radiator. It is back a little further. Could this possible be the water pump or something else?

Kind of hard to tell. Can you hold your computer closer to the car so mine can see it better?

Actually, the hardest part of solving coolant leaks is figuring out the cause, and yours should be pretty easy if it is running out that fast. If you dump in a gallon of water, and it is gone in less than a minute, it is fairly likely it is not due to a leaking water pump. They rarely leak that fast unless this has been going on for a while and has steadily gotten worse.

A ruptured heater or radiator hose is a better suspect. Core plugs can corrode through too, but usually not in 12 years. You may be able to get a clue by observing how much water you have to add to get the level to the top of the radiator. Most large engines' systems hold around three gallons of coolant. If you wait for the leaking to stop, then have to add only half a gallon for the leaking to start again, the leak is near the top of the engine. If you fill the radiator, then it leaks enough to cover your driveway and run out to the street, the leak is down lower.

For real slow leaks you can do a pressure test to make it show up. For really slow leaks we add a small bottle of dark purple dye, then search a day later with a black light. The dye will show up as a bright yellow stain that can be followed back to the source. For a fast leak you have to rely on looking.

when the car is moving everything seems to be fine though when sitting at a long train the car is over-heating and with it seems no loss of fluid, the thermostate , waterpump and hoses are all new, the aux heater pump is less than 2 years old and all of the relays and fuses are good, there are no signs of coolant in the exhaust or exhaust in the coolant and the fan is running

Is the cooling fan turning on? when you sit idle, there is no air flow through the radiator. As a result, the cooling fan should come on to help cool the engine coolant. Once you are moving again, the air flows through the radiator cooling it down.

Let me know.

i turned my car on and let run for like 15 mins took the resovior cap off and antifreeze was shooting out as the car was idleing and temperture gage was rising 2 the overheating mark .i check all the hoses are hott new water pump no leaks and the fans are on ..what can b making it get so hott so fast.and i got a thermostat put in..and i took a head gasket test that they said was ok

You may need to bleed the coolant system. Fill the system and have the heat turned all the way to the hottest setting. This allows collant flow through the heater core. With the radiator cap off start the car and bring to operating temperature. Top off coolant and drive for a few miles. Allow to cool and repeat procedure.

replace thermostat housing on 2004 lincoln ls now overheating

Is it leaking anywhere? if not and it wasn't doing that before you replaced the housing-could be air in the system -try bleeding it out

My thermostat is working, my water pump is brand new, i have antifreeze/ coolant in the car what could be the reason why my linconl is overheating after 3 minutes of driving.

I have a 2002 Lincoln LS 3.9 V8 with 160000 miles and am having the same issue.I have taken it to repair shops and they cannot seem to find the issue.So good luck finding the problem!! If you do hope to hear back.
