Overheating problem My Toro Model 3200 workman overheats. It seems like the water isn't getting to the motor. I pulled the thermostat out but still does same thing. The last time it happened I opened the bleed valve on top of the thermostat housing and only steam came out. Should I look at a new radiator?

You might need to replace the Radiator but try bleeding it again, try this open the bleeder valve and put a water hose in the Radiator with a rag wrapped around it to seal the gap around the hose and turn it on with the bleeder valve open and see if the water comes out if it doesn't then there could be a blockage then remove the thermostat housing and see if it comes out of their and you can do the same with the Radiator also if it comes out of the Radiator slow then you might take the Radiator to a radiator shop they can test it, fix it or sell you a new one,before you remove the Radiator remove the Radiator cap start the engine and watch the water flow to see if it flows fast when the engine is reveed up if it doesn't it could be the water pump is bad and it would need to be replaced

I would take a close look at the water pump
if the water isnt moving through the system it basically becomes a kettle
thats why steam comes out of the bleed nipple

Still overheating, replaced the water pump, flushed the radiater, and removed the thermostat. but overheats after 5 minutes of idle running


leave the cap off while it is idling, look in radiator for any air bubbles, if there is you have a leaking head gasket

Why does my car overheat? The mechanics don't even know...


There are multiple things it could be,thermostat,water pump,radiator,or your belt is loose.Is your coolant disappearing,having to refill,if so then water pump is leaking and needs replacing,if fluid okay,then maybe the thermostat isn't opening properly,but first check belt to see if it is turning tightly.Your radiator may be clogged and needing blowed out.

2001 lincoln ls v6 engine overheats when air condition is on?


replace your thermostat and check the waterpump. The ac "pulls" heat out of the air in the car thereby making it cooler, at the expense of making your coolant heat up even quicker than normal. Try this to see what's going on.. Open the radiator cap, start the engine and wait until the car gets up to operating temperature. You should be able to see the water circulating through the radiator...if the fan comes on, and the water isn't moving, then replace the thermostat. If it still isn't moving after that, the water pump may be no good. Id bet on the thermostat. They're cheap and need to be replaced every so often. If the water is circulating and the fan never turns on, then you check the fan motor, relay, etc. There is also a temperature sensor located somewhere next to the thermostat. It's rare to have to replace that, but if it's faulty, then the fan won't turn on and thus overheating occurs. I am assuming here that if you drove your car up a hill without the ac on, it will overheat or get hotter than normal...So....go test your circulation first and let me know what you find. Oh yeah, when you do the circulation test, turn your heater in the car on full blast too...does it get hot inside the car?

Overheats after running about ten minutes...doesn't overheat while idling.


Seems like your thermostat is going out, meaning that it is not opening all the way anymore, at idle its not a problem, no hi RPM on the motor, but as you rev up, temp increases, thermostat not opening all the way obstructs coolant flow so the block does not cool off properly.
Another thing to look at is your water pump, is the fan clutch working properly?
Obstructed radiator, it may need a good flush.
The car is over 10 years old, so expect it to start having issues. I'd advise to check your ******, do a maintenance on it. (filter and fluid change)

Engine Cooling problem 2000 Jeep Cherokee 4 cyl


Although the 4 cylinder is too underpowered to have air conditioning in my opinion, it still shouldn't overheat within 10 minutes unless something is wrong. If your Jeep doesn' not overheat when you are driving WITHOUT AC on then your compressor might have a problem and causing the engine to work too hard to turn it.

But if it overheats without the AC on, then the first thing you need to do is check the cooling fan and see if it operates! There has been a lot of problems with the cooling fan relay on this model. If that isn't it, then move to changing the thermostat and checking the water pump.

Running hotter than normal looks like it started leaking bad under motor now


There is well-established procedure for trouble shouting the over heating.
Does the car overheat in driving mode?
Yes.
Are you losing coolant?
No. Check water pump (including belt) and thermostat.
If yes make a radiator compression test. You might have a bad cylinder head gasket.
The car doesn’t overheat in driving mode, but overheat in idle.
Does the fan runs?
No.
Check the fan assembly for a bad motor, loose fan blades, or bad connector.
Check the codes for a bad temperature sensor.
Check cooling fan relay and fuse.
If this isn’t enough to solve problem, then send the car at dealer for a “check and advice”.

Ford Escape 2003. Engine suddenly overheat.


Engine over heating can be caused by a number of things. When you say the water pump and radiator appear to be ok I am also guessing that you checked the coolant level to make sure it is normal.

If the level is low then you obviously have a leak. Insufficient coolant circulating will not cool the motor properly because it won't be able to draw enough heat out. If the level is normal then you need to check the thermostat to make sure it is opening properly. To do this, run the motor to temperature and check the top and bottom hoses. They should both be hot and firrm once the thermostat opens meaning the circulation loop is operating properly. If the top is hot and firm and the bottom is cold/soft or collapsed then the thermostat isn't opening.

If the thermostat is operating properly then you ned to look for some other obstruction or cause for coolant loss. Check the head/intake gaskets, hose connections, hoses, over flow tank, radiator fins, radiator side tanks etc..

Good luck.

1982 Landcruiser, overheating


I would suggest to check to make sure the fan is not on backwards. I dont know if its possible to even put it on backwards. just check to make sure that the fan is pulling air thru the grill instead of blowing out the grill. Also look into the radiator and see if you can see any lime or sediment in the radiator tubes. It will be white in color.A small amount of scale on the inside of the tubes act as insulation, and keeps the coolant from contacting the tubes and transfering the heat to the tubes so the air passing across the radiator can carry it away. Just flushing the radiator wont remove the lime scale, the radiator would need to be remove and dissassembled and rodded out. I dont think you have a blown head gasket yeti,if it not blowing water out when its cold and you dont have any performance problems, runs fine, just overheats. You might try turning on the heater when it starts to overheat and turn the heater fan on high as it acts as a radiator and see if it cools down indicating the cooling capacity of the radiator is diminished
