SOURCE: HELLO I AM HAVING A WATER PROBLEM ON MY 1993

Sorry to tell you that your problem is YOU have a Head gasket blowen OR a Cracked head, either way you have to remove the head and take it away for Crack testing and surface grind (max 4 thou) no more.
If all ok when done replace with new VRS and refill with coolant (but turn on the heater to hot before filling to remove all AIR

SOURCE: 1993 Toyota Camry V6: Engine Overheating Prob

Yes if it hydraulically operated it could be because the pump for the fan is bad. If I am not mistaken the fan is run off of the power steering pump correct. check and make sure the pump is working correctly. I have not seen a hydraulic motor on a car I know they put them on a lot of diesel trucks like humvees and some Chevy diesels but not on a car. Most are usually electrical. I know on humvees with a hydraulic fan they have a fan controller check this and make sure it is working right you can unplug the controller and the fan should stay ingaged and turn faster.

OVERFLOW IS BOILING


If the thermostat is not opening, the engine will keep getting hotter as you drive. You could be low on coolant and have air pockets in the system which would cause the temp gauge to not be accurate. Is the radiator fan coming on when the tank is boiling ?

2004 explorer 4.0 coolant reservoir boils over when stabolized at normal level, no heat when level drops temp indicator normal


go to autozone rent the free tool called a block tester buy the fluid for it (about $8.00 us)drive the car make sure the resivour is about 3 inches down so you dont suck any fluid into block tester. pour blue fluid into block tester put it in antifreeze resavour. squeeze bulb sucking air from resouivour for up to 2 minutes if fluid turns yellow your head gaskets are leaking. I think you may find this to be your problem

Engine overheats and heater blowing cold air


You have air trapped in system , change thermostat , bleed air from system , let it run hot while adding coolant with blower full blast on all front and rear heaters .

Coolant boils,whats the problem?


Hi Odnanref, If the coolant is boiling you have a problem with the cooling system. If you cannot see a leakage have the thermostat in the engine checked and replaced and hope that you have not overheated the engine to the extent of needing a cylinder head reconditioning job carried out. The AC is effected because the condenser is mounted in front of the radiator and depends on cooling from the fan. If the engine overheats the AC will be unable to cool. Regards John

My toyota rav 4 is overheating iit is boiling from the reservoirtank what can i do l have changed the radiator and the thermostat checked all the hoses but it is still boiling can you help me please


Check fan operation. It should come on at approximately 102 degrees celcius.Which fan drive do you have? The older RAV 4 has a hydraulically driven fan while the later models have an electric fan. Both are "turned on by the computer". So check for the thermo sensor at the coolant outlet from the engine. As it gets toward boiling point you should find a lowered resistance of approximately 200 - 300 Ohms there. When cold these sensors run in excess of 2500 Ohms.On the older models with the hydraulic drive it is provided with hydraulic pressure from a pump in the transmission. Check for transmission fluid level and pump operation by loosening off the supply hose and starting the engine in neutral. If the pump is inoperative no oil will be supplied to the hydraulic fan motor. Happy hunting.

My car is rumming hot and the antifreeze is leaking I'm thinking it's my water pump


It could be the water pump , or something else , like a faulty thermostat. Where is the coolant leaking from ? If it is leaking from the water pump , then yes , your pump might be toast.
If the thermostat is no good , the engine will warm up to normal temp , and then overheat quite quickly. As it overheats and the coolant expands and boils , it could back up into the overflow reservoir and leak out onto the ground. You need to get someone to diagnose the problem ASAP , running your engine in an overheat condition could very quickly blow your head gasket and/or warp a cylinder head. If you can , please post a bit more info. Does it run but at a higher than normal temp. Does it only overheat when stopped in traffic etc.
Could be water pump , or thermostat , or plugged up radiator , or nonfunctioning cooling fans.

Temp gauge is in normal, 200 degree, range when starting. Within a few minutes of driving goes up to 250, right below orange line. No leaks found, coolant level appears fine. Any ideas?

My 1997 Dodge Intrepid overheats. I've replaced the thermostat, and it continues to overheat. I noticed adjacent to one of the radiator hoses, a ribbed hose that is split. Could this cause the car to...


Now that you've eliminated the thermostat, it could be a number of other things. Don't drive the car too far until you've fixed the overheating problem - overheating can destroy an engine.

That split ribbed hose you see is plastic wire loom - it carries and protects electrical wires, and is not the cause of overheating.

1. Low coolant level
2. Radiator hose split/cracked, causing low coolant level.
3. Head Gasket - leaking, causing low coolant level
4. Thermostat - stuck closed (you eliminated this possibility)
5. Radiator cap - worn/damaged
6. Radiator fins - obstructed by debris/cardboard
7. Water Pump belt - missing/broken
8. Heater Core - leaking, causing low coolant level
9. Intake Manifold Gasket - leaking, worn, damaged
10. Radiator Fan Relay - faulty
11. Radiator Fan Blade - broken, missing
12. Radiator Fan Sensor/Switch - faulty
13. Water Pump - leaking, causing low coolant level
14. Radiator Fan Motor - faulty

My primary suspects would be Rad Fan Relay (#10), and
Rad Fan Switch (#12).

Overheating when driving no mixing of the coolant and oil


The three most likely thing's cause overheating are faulty thermostat,electric fan or clogged radiator. Only at has been overheat so much it boils dry that it will cause engine trouble. Most common problem's are blown cylinder head gasket or a cracked cylinder head.
mixing coolant and water depends on where the gasket has blown or head is cracked. You will first need to check if it actually is overheating. The reason is. If the head is cracked or gasket blown then you can get a false boiling which is compresion from the cylinders blows through the crack in the head or gasket causing the coolant to blow out of the radiator cap.Fill the radiator to the top leave the cap off then start the engine.If the water blows out then you will need to remove the cylinder head check the gasket is ok. If its damaged replace if not get the head checked for crack's. If no water blow's when you start it check the thermostat is working properly. To check the thermostat put it a in a saucepan cover it with water bring the water to the boil. It should open before the water boil's but near boiling-point. If its ok then start the engine again leave it running until it boils and check the fan is running. If that's ok then its radiator problem. Their is no way to check if the radiator is ok you will need to get a new one. One last point. If the cylinder head or gasket are faulty it was caused by overheating so by just fixing the cylinder head problem is not a cure it will overheat again. Check the three things I mentioned at the begining and told you how to check them. Hope this help's. Cheer's

Overheating,reserve coolant tank boiling I have a 2000 Ford Taurus with the similar problem. I had my water pump replaced then this started.


Ford 2000 Taurus

To solve the problem you have the things to do in this order;

) When the engine is cold top off the radiator with fluid. (When the pump was replaced the fluid should have been also)
) Make sure the radiator fluid has anti-freeze in it. This is also anti boil also !
) Add fluid to the overflow reservoir.
) Make sure the drive belt was replaced on the water pump.
) With the engine running, you can add fluid to the radiator for the first minute or so. You want to get air pockets out.
) Replace radiator cap.
) Let car warm up. When it's hot you should get the radiator fan coming on.
) When it get hotter the air-conditioning fan may come on.
) If the fan does not come on, the heat sensor is probably bad.
) If all fans come on, and it overheats, you may have a bad thermostat. Trace the upper radiator hose to where it connects to the engine. That's where it located.

Do not operate the engine when it overheats, You will damage the head gaskets and cause radiator fluid to leak into the cylinders.
If you smell radiator fluid in the exhaust fumes, it may already be leaking.
