Temp is running hot..put water in still does it..radiator and water pump have been replaced in the last year..see no leaks

what is the problem do you have hot water ,have you bled the rads.
it could be an airlock,if you have not bled the rads turn off system and bleed the one at the end faraway ,then bleed all the way up making sure pressure is up you need to have that.

MY fluid in resevoir is bubbling in my 99 A4, just had timing belt and water pump replaced a month ago anything????

1. Possible air lock in the cooling system, does the internal fan blow hot air? You can blead the system through small bleeding points on the water hoses.

2. Head gasket gone, do the water pipes to the rad expand under pressure?

3. Faulty thermostat. Thermostat controls the amount of water directed to the rad.

Let me know how it goes.

TWO- poss.head gasket on backwards or coolant sensor not turning on the cooling fan on , also you have to bleed the system which is located on the housing going to the top rad hose at the engine.

Audi a6 2.8e keeps over heating the fan on the first speed does not come in.The water is pushing out the cap.Did replace the water pump,pressure cap,fan switch,bleed the system no air in system

Sounds as if the cylider head gasket may have blown. If the engine oil has changed to a grey colour, thats the problem. Even if the oil hasn't changed I'd suggest a cylinder compression test fromyour friendly motor machanic

My Toyota Hiace high roof with 3L Diesel Engine heats up. This was after the cylinder head was skimmed and had new valves replaced. Please help me. How can I stop this heating up? Cannon

Your thermostat may be staying closed, if the top coolant hose becomes hot after the engine running for a while, then thermostat is opening ok. Next check to see if the bottom hose going to the rad is getting warm. If its staying cold then you may have a problem with the water pump not circulating the water around the cooling system. If thats ok check the rad cap is sealing ok. when the engine gets up to normal engine temperture remove the reservoir top filling cap which has a rubber pipe going to the thermostat housing. with the engine running there should be no water coming down the pipe and exiting the filler cap. If there is it could be the rad cap not holding pressure which it would need to be replaced or the head gasket is leaking and pressurising the coolant system.. hope this helps you..

2006 Equinox over-heating

There is a few things that could course your car to be over heating

  • Air In Cooling System
  • Coolant Leak
  • Water Pump Failure
  • Head Gasket Failure
These are some of the common problems as your car is reasonable new i would't think the head gasket has gone it is more then likely what you say that the water pump is broke probably the impaler has broken off. To bleed the system you need to get it up to running temperature and remove the bleed screws in the cooling system starting from the highest one working down then back up. If you find it is hard to bleed and no coolant is being pushed out it is more then likely that the water pump has gone. To test if the head gasket has gone take off the oil cap and look for a mayo type gunk around it if there is then this means that water is getting into the oil system meaning the head gasket has gone another test is to use a spacial liquid that test for exhaust gases in the coolant system.

Not sure if new thermostat is allowing water to flow.

has the cooling system been fully bled of all air pockets- this is done by allowing the car to fully warm up at idle with the rad cap off - allow to run upto temp until cooling fan cuts in - has the cooling cicuit got a seperate bleed screw - are you loosing coolant - or have you been - has the vehicle ever over heated ? curious - as you may have a faulty water pump - or even worse the head gasket may have blown causing cylinder head gases to laek into cooling system - i recommend a block test at you local garage - if its ok - get the water checked asap - andy

My 1994 acura legend keeps overheating

when bleeding the system to get the air out, you may want to turn of the heater to help get all the air out of the system.
