Hi, Tom and the usual suspects are:
1. Low coolant level.
2. Restricted radiator air flow.
3. Faulty thermostat.
4. Coolant pump or fans inoperative.
5. Vent hose crimped.
6. Air in the coolant and needs bleeding.
7. Engine idling too long or bike moving too slow.
8. Coolant too old needs to be replaced.

Can a bad heater core (apparent small leak) cause overheating?

Yes. The engines coolant goes thru the heater core to provide heat. If it leaks out enough coolant it can result in overheating.

Over heats in traffic fluid is boiling

So the first thing you do is check for trouble codes.
Overheating in traffic can often be a cooling fan problem.

My 2005 KLR 650 is overheating but I'm not sure of the cause. The metal box under the seat is incredibly hot but I don't know its purpose so I was hoping you can give me some ideas


This is normal, my 87' would do the same thing. There are two mod's all KLR owners should do...
1. Install an overide switch for the fan, mine is a three way
2. Cut off switch for the lights.(Great for crawling around off road)
The overide switch for the fan helps keep the temp down below the red. Now, I have never sat in a traffic jam on a 100 day, but it has helped with everything else thusfar

hope this helps

My 1999 jetta keeps overheating. When I stop at the traffic light the temperature moves a little past the 190 mark. When I start moving it slowly goes back to 190. What might the problem be?

Does it make a difference if you increase RPM's when stopped at the traffic light? If so, you have a water flow issue. If not, most likely your radiator fan is not working properly.

Ford Escort 1.9L - The fan for the radiator does not come on and the car overheats. I have checked the fuse & its fine and there is water/coolant in the radiator. What can it be?

if the car is overheating whist driving it normally and not sat in traffic then it could be as simple as the thermostat needs replacing, are you using water if so your head gasket could have gone as for the fan the temp sensor could have gone unplug it and short the connections on the wiring the fan should start up ( ignition on) if it does replace the sensor

Overheating again

The heater stopped working because there was no coolant in it. Your real question is where is the water going.

Have the cooling system pressure tested to be sure you have no leaks. You said you had the radiator flushed, I suspect some of the tubes are blocked, it should be dissassembled and rodded then cooked out. Not just flushed. You problem is in traffic, low speed. The car starts to over heat, it blows the water out of the overflow, the level is down, the heater stops working, then you are out of water in the engine and overheating.

BTW ground the wire that goes to the warning light sensor and be sure it lights the warning light. If htis is the case the sensor is bad. I assume when you turn the key on but before starting the light does work then, correct? That means the bulb is ok, that does not check the sensor.

Good Luck!

Vitara 1.6 cuts out

Are you quite sure it is not overheating? Your mention of heavy traffic, ie. stop and go, would tell me that your radiator fans are not working. I had a car with bum electric radiator fans. It worked fine if it was moving a lot. But in slow traffic, it would get warm enough to have a vapor lock or something without setting the engine-hot light.
