Engine Overheating?

I drive a 2001 ford taurus SES sedan with 164k miles. After driving about 10-15 miles and I come to a complete stop (Idling) or Parked my car begins to smoke from steam coming from the cap of the coolant box, the cap is on there correctly and the hose was just replaced

coolant system pressure test should be done to check and locate the leak
inspect plastic container for cracks

I experience sharp rise in temperature guage when air conditioner is put on. It comes down & stabilizes when aircon is put off.

radiator fan is probably not coming on when a/c is switched on like it should, most likely culprit is defective a/c pressure switch

small leak from thermostat housing, and heater cor line. if i fix both leaks will overheating stop? waterpump seems to be okay

Leak always cause coolant lose and engine will overheat
run the engine long while overheating and engine will be ruined
and or damaged
so fixing the leak should be a most
and as a 1st step

car is overheating, have changed thermostat had system flushed, replaced coolant resevoir(old one had several cracks ). coolant has a dark discoloration. it drives for approx. 5 miles before overheating. doesnt appear to be any coolant in the oil or transmission fluid. cannot find any leaks on the exterior .

Do a coolant flow test and check
check headgasket

I have a ford taurus and a few weeks ago I noticed that the car was running hot. I checked the coolant and is was low so I filled it back up again. I then realized that the fans were not working so I took it to a mechanic and had that problem fixed. The issue now is that when the car is on it is spewing coolant out a valve by the resovior. What could be causing this? Is this the sign of a bad water pump? I changed the thermostat not long back. Could the block be cracked?

What you need to do is have it block and pressure tested. If its not being caused by a bad water, thermostat, clogged radiator or airlock in the system.

My Taurus is overheating and I'm not sure what the problem is. I'm seeing the steam coming from the back hose on the overflow tank. Not seeing much action in the overflow tank other than that.

first check coolant level. if OK then ensure cooling fan(s) are coming on properly. also remove and test thermostat. let me know how these first few things look.

driving car on hwy,it lost power and overheated. took out plugs this morning had water in middle well where spark plug goes, could this be a head gasket or something else

When you say middle well, are you refering to inside the cylender?

yes the cylinder where the spark plug goes into

Check the valve covers for leaks and let me know what you find.

would need to be able to start car to check for leaks correct,if i dont how do i find these leaks, with out starting engine

Since it was coolant, you could pressurize the system to see if you can see the leak. The tester is nothing more than a hand pump. Most parts stores will lend or rent them to you.

why is my car overheating?

Could be a problem with the thermostat, clogged-up radiator and the water pump-start at the thermostat, replace it and see what happens-

2003 Taurus cooling fans. Turn on when Car first starts, once they stop they never come on again. Car overheating. Replaced thermostat and fan relay. What else to check and where located please. Thanks in advance

Also does not come on when ac is on. Another thing to add, I've got a odd looking sensor of some sort that appears to not be in the correct place. It's got a series of coils contained in a metal vented housing. It was found just sitting atop the fan housing zip tied in place. Not my car, so I know very little about it. Thanks

check the relays for the fans andnot seeing or knowing what it is you aredescribing makes it hard for us to tell you why or what it actually is. the thing ziptied to the radiator may have worn through the fanwiring. the fan relay is in the junction box 1 in car. because the pcm turns the fan on then there may be a broken wire someplace

Thanks for the quick response. I am at work right now but will upload a photo when I get home. The thing that bothers me is that when you first start the car the fans run for a few minutes then shut off.. Aside from the pcm, is there anything else that triggers the relay? I have Alldata for all My cars, but this is a friends car. A wiring diagram would be nice at this point.

hopefully this will come out ok. there is a resistor near the fans it has a blue wire and orange. see if the power goes in and out. there is also a relay for high speed. maybe one of these are bad.

if you need to enlarge this, save it ina document then enlarge from there. I can't do any larger

Here is the aforementioned "mystery part ". Any clues? I am about to do some more diagnosing and hopefully get this thing fixed. Thanks for all your help. Greatly appreciated.

that is the resistor for the fan i mentioned in my reply. i'd replcae it and see where it goes near the fan it may go someplace on the shroud and the shroud may have broken off. you might test it to see if it's got power going in and out with the a/c on . it shold work then

Still haven't found exactly where the resistors Home is. Even tried replacing the coolant temp sensor in case it was sending inaccurate readings. Tested every relay and wire continuity, and everything is checking out. Could I possibly be dealing with a bad pcm? Not sure what else to check at this point.

it cold be a bad pcm, but i doubt it i would go for a bad connection or broken wire first.where the resistor goes by the fan may be the sshroud is broken at that point there should be a recctangular hole with a cople of small holes for the push pins to go into. it cold also be n a fan bracket.

Okay, so last summer it started to overheat and replaced the water pump and radiator was fine until about March or April when I was taking my kid to work. I looked down and seen that my temperature gauge was on the "H". I pulled off the freeway and sat for thirty to forty five minutes then started it up and got it home the next couple of days it was fine then all the sudden the same thing happens and then periodically after that. Eventually I blew a head gasket and had that replaced all with new wires because they were melted anyways. I also replaced the water pump again because I had replaced the reservoir tank with a clear one and noticed it was rusty all over again. so I figured the one I first replaced it with happened to be from a pick and pull so I thought maybe that was it. So after taking out the water pump and seen that there was no reason to replace it, although I still put the new one from the parts store on anyways on my way home got hot again. My question is, can the heater core make your car overheat if it is plugged, and can I bypass it? I have noticed that my fans do not stay on when I turn the car off even when it is overheated could that be the issue?

The heater core will not make it overheat, but it does sounds like the head gasket are blown of you have a cracked head to confirm the issue lets go over this guide to test. You can get the kit from Amazon.

My car has MFI OHV engine that recently started over heating and coolant is spraying out from coolant tank. Since it started i have replaced the thermostat, water pump, radiator cap and flushed system out several times. Also, radiator seems to be okay getting hot on both sides like its working and checked hoses an do not see any leaks. Since doing all that it is still over heating. However, it is not over heating instantly it is after driving the car for a while that it starts to over heat. I am doing all work at home since i cannot afford to take it to a repair shop. Other than a blown head gasket is there anything else i might be missing?

There's a chemical test that can be done in a few minutes to check for a leaking cylinder head gasket.

Given the age of the car, another good suspect is corroded cooling fins on the radiator. If they crumble when you rub your fingers over them, they are corroded to the point they can't give up their heat to the surrounding air.

Also check for a missing rubber seal under the front edge of the hood. That will allow air to bypass the radiator. Be sure the radiator fan is turning on. If that is the cause of the overheating, that will not occur at higher speeds when natural air flow is sufficient.

What is the name of the chemical test?

Here is a guide to show you how it is done.

small leak at thermostat, and in heater core lines up against firewall, no sound or looseness from water pump. ifboth things fixed, will overheating stop?

Leak need to be fixed as a 1st step

the hose to the coolant resivior loosened and started leaking coolant. as a result the car started the loose speed and the engine lights came on. we pulled over and it started to smoke/steam. it would still start but we didnt want to risk further damage. 2 days later it wouldnt start. im told head gaskets are bad. what would you suggest.

Start by checking the compression on each cylinder. Romove all plugs and install compression gage on one cylinder at a time and crank engine. each cylinder should be very close to the same.
