mu overheating

[muzila]

When the mu is hot carefully run your hand over the front of the radiator. feel for cold spots. if you have those then its blocked. flush it out. If that dont work get it replaced or recored. Other wise you just have to trace the water flow to find the blockage.

Or it might be somthing else. But you say your not using water so I wont go into head gaskets and the like.

More info please.
Under what conditions does it overheat? If its ok at speed but overheats driving slow look at mud blocking the radiator, faulty viscus fan or blocked radiator core.
if ok slow and hot at speed look at blocked radiator or injection timing out.
Also if auto this can affect things

Had the same problem with my sons nissan. The blades on the water pump had rusted off.
That could be another reason for no flow.

That come up on an isuzu or 2 as well. If the anti freeze has always been good this shouldnt happen

Could also be a sensor that is faulty
