My 1996 grand marquis keep overheating


there are several problem that will give this indication and your information is not comprehensive enough to make a good diagnosis
the time factor is critical as some time could be 5 minutes to 5 hours and driving is too loose as it could be at highway speeds or stop go traffic , hill work or under load
so I will give to certain conditions that will over heat the car or cause a rise in operating temperature
head gasket--check with compression test
low water level-- check at cap
faulty radiator cap--have tested
partially blocked radiator--have a flow test done
fins on cores falling off --replace radiator
overheating transmission oil--check the transmission is fully operational as high speed with out over drive in will cause a rise in temp
if in traffic --check viscous fan and fan operation if electric
if under load -check load and tyre pressures
check for brake operation- adjust hand brake to full off
run the fault codes to check air/fuel ratios and timing
check for failed cat converter-- blocked exhaust system

My pajero is overheating afew minutes after starting what could be the cause?


An overheating engine is more than a bummer, it can be an expensive engine killer that will leave you on the side of the road, then on to the repair shop for an expensive repair bill. If your car has been running hot, you know the feeling. You're sitting in traffic, the light turns green, and you pray that traffic breaks enough for you to get some air flowing over the radiator so that engine temperature needle will go down just a little bit. It's beyond stressful, and there's no reason you should be forced to endure this. The fact is, there are only a few things that commonly cause an engine to overheat regularly. 1. Low Coolant By a large margin, the most common cause for engine overheating is simply a low coolant level. Your engine's cooling system relies on coolant to circulate and remove heat from the engine. If you don't have enough coolant in there to do the job, heat will build up and your engine will overheat. No amount of running the heater in the summer will help if you don't have enough coolant in the radiator to transfer that heat. By far, the first thing you should do if your engine seems to be running hot is check your coolant level. 2. Electric Cooling Fan Failure If you have an electric cooling fan that isn't coming on, this can cause your engine to overheat. The electric cooling fan draws cooler air through your radiator when your car isn't going fast enough to ram it through from the front. You can test this by letting your car idle long enough for the engine to heat up. If you've been having an overheating problem in traffic, keep an eye on your temperature gauge. When it starts creeping into the danger zone, look under the hood to see if your electric fan is running. If it's not, you'll need to figure out why. There are two usual causes to this:
2a. Bad Electric Fan: Sometimes your fan motor will just burn out and your fan won't come on at all. To test this, find your radiator fan switch and disconnect the wiring harness. Get a jumper wire and insert it into both contacts, your fan should come on. Another way to test the fan is to turn on the air conditioning. Most, but not all, cars activate the cooling fan at either a medium or high speed when you turn on the AC.
2b. Bad Radiator Fan Switch: There is a switch that tells your cooling fan to come on when your coolant reaches a certain temperature. The easiest way to test this switch is to disconnect the wiring harness and then run a jumper wire across the harness contacts. If the fan comes on, you need to replace the switch. 3. Thermostat Not Opening The most common symptom of a failed thermostat is overheating at highway speeds. Your engine may be able to stay cool at low speeds because it's not working that hard, and therefore not creating as much heat. But at highway speeds your engine needs lots of coolant flowing through. If the thermostat doesn't open, there isn't enough flow to keep things cool, and you'll find yourself looking more like a steam ship than a sedan going down the highway. 4. Broken Fan Belt There are still lots of engines out there which have a fan belt to drive the engine cooling fan. If you see a belt attached to your fan, you're in this club. The good news is your repair is always cheaper than the electric guys. You can replace your fan belt easily if it's broken. 5. Clogged Radiator If your car has more than 50,000 miles on it, your radiator could start getting gummed up. You can avoid this and other problems associated with old coolant by flushing rad every year.

My 2003 dodge durango keeps overheating , i just had new radiator put in and it started overheating again but now it is overheating with a very loud screeching noise like a belt sound what could be ca


as for noise will have to inspect under hood,could be fan or belt or pulley ,water pump .these are some things it could...My suggestion for overheating is replace thermostat. If your car has electric cooling fan then it may not be working..turn defrost on and if fan kicks on then fan motor is good..Now this does not mean that fan is working properly because fan is controlled by heat sensor switch that kicks fan on when motor reaches heat range......Things i would have checked....hope this information helps and good luck and Please rate my post...

Sounds like your cooling fans on the radiator are not working. The fans are activated by a thermol switch on the engine or radiator reading the coolant temperature and an A/C switch. When the coolant is too hot the fans should activate cooling the system down. And, when the A/C is on the fans should also activate in order to cool the condensate so the A/C would work.

When you are driving, the movement of the vehicle throught he air is providing enough air flow to keep things cool and functional.

I would check the radiator fan fuse or fuses first. If those are OK I would try to run the fans with 12 volts and a ground that I supply just to see if the fan motor(s) actually run when powered. If the fan don't run when powered then the fans are bad and will need to be replaced. If the fans do run when you power them manually, then something is not allowing the power to activate, like a relay, control unit, or wiring.

It will take a little diagnostics, but it is not too difficult to chase it down.

If your car is overheating then everything is not ok in the cooling system. If it happens mostly in traffic make sure the coolant level is not low and that the cooling fans are functioning.

u should check for a faulty thermostat first, they are only a few quid and easily replaced. if no change ur most likely faults are a blocked radiator or faulty water pump. u dont sayhow old ur van is but after the thermostat go to the radiator, when its hot check the bottom of the rad to make sure its hot, also brown water means u need to bback flush ur cooling system. even tho u have changed some sensors doesnt mean u got the fan switch sender, dash board sender and fan sender tend to be different sensors, so just double check.

It faintly smelled like coolant inside the car


Usually when the windows are closed and the smell of coolant gets inside the car means the heater core has a leak. The leak can be the very tiniest and the smell will be very noticable to anyone. If the windshieild fogs up the leak is getting larger.

Check the radiator cap ton see if its holding the correct pressure. That will cause the temperature to fluxuate as well.

My m6 keeps overheating in slow traffic after a while.BMW have changed the fan twice but this has not solved the problem. Any advice?


if you run the a/c in slow traffic it will cause more heat in the engine bay then the car can ex spell if that is not the case try putting in a new thermostat and also when the thermostat is being replace have a very through cooling system flush done.hopefully this helps a bit.
