SOURCE: ford ranger truck overheating

I have had this happen with my ranger. Changed everything I could to try to fix the over heating. It turned out that I had a small leak in my head gasket and it was allowing exsaust gas to go into the cooling system witch was over pressurizing it. Also the air from the exsaust will heat up much faster than liquid making your thermostat to read hot and will not be able to blow hot air in the cab because there is no liquid going to the heater core. This happened to me when my blet came off and I tryed to make it home. If you had it over heat for a long peirod of time it may have ripped the head gasket.

SOURCE: 96 Dodge Neon, not you average overheating issue

Hold throttle open to a normal highway RPM in the driveway and observe rad hoses for collapsing. Do your run up the road & see what rpm your at when gauge starts to move toward hot, then use that rpm, in driveway . You did run that engine for quite a while with rad cap off when you refilled coolant, with heater on correct?

Check your oil dipstick for coolant, or a mucky substance. Your symptoms sound like a blown head gasket.

Changed bad water pump and timing but car is still overheating causes


Overheating is not always caused by a bad water pump or bad engine firing timing.

The most common causes are:
  • faulty radiator cap: steam/water will be escaping from the caps when engine is hot or oveflow tank overflows or empty!
  • crack cylinder head gasket: check when engine is cold thru radiator cap hole for milky oil in water radiator or large bubbles in radiator water after starting engine. Also check if water steam comes out of exhaust.
  • cylinder head itself: same symtoms as for gasket above.
Hope it helps you find your problems.

1995 toyota avalon, overheating,just changed s/belt compressor stop working, now it runs hot. is this now a prblm with water pump or first thermostat?


I do not see a good connection between the serpentine belt and the engine overheating suddenly.

Perhaps you have a lot of burnt belt rubber on the water pump pulley?

Is the upper radiator hose hot? If so the stat is opening. If you start the car cold with the radiator cap off you can watch for coolant starting to flow and make sure the stat works...if the flow is low you have either a blocked stat or poor belt grip at the waterpump. Have you flushed the radiator recently? After 15+ years your car could be ready for a cleaning.

My 1999 dodge neon is overheating and just changed water pump and thermostat radiator. No leaks and no water in oil. Changed thermostat again and same problem . How can you tell if water pump is bad and...


Last time I had this problem I had a cracked head. With the cap off the radiator, run the engine at idle to operating temperature. When your looking in the radiator you should see the water circulating if the water pump is working. When you say the motor is over heating, if you have fluid coming out of the over flow hose then yes you are most likely overheating, if you are just seeing the gauge indicate you are over heating you may just have a bad engine temp sensor.

Which way does the waterpump turn on a 1985 Ford LTD 302?


The feature than can determine the way the pump turns would be whether they were driven by the smooth side of a serpentine belt on the one had, vs. the grooved side of a serpentine belt or a V belt on the other hand.

It would really be a good idea to get a numeric reading on the engine temperature...

Of course, the number one issue is the thermostat. If it is too high of a range, or is not opening properly, the 4-core radiator will never be called on.

Next is the possibility that steam/vapor is collecting around the t-stat. I had a big problem with that in an Aries K. Once it got hot enough to open the t-stat a few times the temperature settled down.

If the fan is not doing its job sufficiently you will get overheating at stop lights and in crawling traffic, but cooling that is fine above maybe 15 or 20 MPH.

If the bottom radiator hose has failed, it can collapse due to the suction of the water pump. For the whole length of that hose you should not be able to flatten the hose by hand. It should have a spiral of wire, a "spring," inside it that prevents that. If that wire has corroded, and isn't doing its job you can get compromised flow.

When the engine is cold, start it up. Before long, the heater hose that comes out neat the t-stat should start to warm up, while the upper radiator hose stays cold. The closed t-stat forces circulation through the heater system. This causes flow over the hot surfaces, and carries the heat from the area of the cylinders to the area of the t-stat. without that, the water's heat would take 10's of minuted to get to the t-stat.

Next, when the heater hoses get too hot to touch comfortably, but before the engine overheats, the upper radiator hose should start to warm up. The t-stat will start to open, and a little hot water will sneak out of the engine, heating the hose a little. That will introduce a little cold water from the radiator into the water pump, where it will get quickly mixed with the water circulating through the heater system, closing the t-stat pretty quickly. So the initial warming of the upper radiator hose will be pretty slow.

If it overheats before the upper hose gets too hot to touch, you have a t-stat problem. Either the t-stat is failing to do its job, or it is not getting the heat signal it needs to operate properly.

If the heater system is clogged or plumbed wrong, it will not allow the requisite circulation.

I hope this gets you on the road to fixing your overheating problem. A 302 with a mondo radiator as you describe should have no overheating troubles, even in the desert!

My car is overheating and i need to know how to put in the water pump?


Is the water pump leaking coolant? If not, then why do you think it's bad?

If the engine is overheating, there are several other things to look at before you consider the replacing the water pump.

Are the fans electric motor driven, or fan belt driven? If fan belt driven, replace the fan clutch. If electric motor driven, check the fan control module and/or fan motors to make sure all is good there. Fan control module tend to fail in weird ways, so if nothing is wrong with the motors, replace the module.

Always, always, replace a thermostat that has overheated. Once overheated, they consistently fail. Make sure you properly refill the radiator with coolant after the stat is changed.

Check that the bottom radiator hose does not collapse.

Check the radiator for corrosion. Boil the radiator out, or have it done, or replace the radiator.

Overheating


Check the radiator and make sure that it is full of water. It can fool you sometimes after you made the repairs, and there could have been an air bubble in the system somewhere, and while you thought there was plenty of coolant, there may not have been.

Always keep the radiator cap off the radiator while filling after a repair like this until you know the stat has opened. You will know it has opened when the water level drops, or you feel warm water entering the radiator. Then replace the cap and fill the reservoir.

If you have gotten the stat hot, then I suggest replacing again as they usually fail closed, particularly when over heated.

If the belt is turning the water pump, then it doesn't need to be replaced.
