My 1.4 corsa utility is overheating we have put in new water pump new thermostat but it still overheating

you may have a blown head gasket or you still have air in the system. take the expansion cap off fill water to the top. run engine and when thermostat opens squeeze the pipes all round the engine to help remove the trapped air make sure the heater is on full heat and number on fan speed. when the air looks to be out and the fan comes on to cool the engine down shut off the engine. if air is still there rev engine a few times this will force more water out so top up to the top and squeeze pipes, keep doing this till there is no bubbles coming out of the expansion tank. when done leave to cool down and then top up and put cap back on. if this doesn't work and you keep getting air in then you need to have the head compression tested, or do the same with a bottle of radweld in the system. use the bottle that works with antifreeze, do as before but with the radweld in. it will leave a copper coating around the system and header tank. this is normal.

87 porsche 924s. Cor overheating at idle. Coolant and oil look normal. No smoke. No heat coming out of vents. Replaced thermostat. Still overheats. Seems to have flow but not sure. It seems the heater core...

run the car with the radiator cap off or the expansion tank cap off, which is part of coolant system and is pressurized, not to be confused with an overflow bottle which is not pressurized, and the heater on high. drain some coolant to allow for expansion. look/listen for bubbles. air from the vents should get hot. give it about 20 minutes

Hi, My 95 2.8 Pajero (turbo deisel) has been overheating. I have replaced the thermostat, water pump and the rad cap (rad replaced 2 years ago) and still it is boiling over into the expansion bottle. When...

Just a guess but I think their diagnosis was that the head and head gasket was not leaking and not a source of the bubbles you spoke of.
Usually when the head or head gasket is leaking, a unusual amount of water will will be expelled from the tail pipe.

When you shut off the engine the overflow jug bubbles,i've already replaceds the head gasket and it doesn't seem too be overheating and it doesn't do it when its running?

You could have an airlock still in the system. Run the vehicle at idle and squeeze the top and bottom radiator hoses with the expansion bottle cap removed. Add fluid gradually to it keeping it under the full marker. The bubbling is super hot air caused by air trapped either in the engine block, or top of radiator. A little tip while doing this, have the heaters on in the car and on high heat with the fans running at high speed. If you notice the engine getting warm and the heating in the car stays cold, the airlock is going to need a bit more work. Eventually if you have replaced the head gasket correctly the air lock with come out. Hope this helped...

VW Scirocco overheats

On some water pipes there are plastic bleed units. You could also try and bleed the system as follows. Inside the car set the heater to full. Then take the cap off the exspansion bottle. Now run the car and feel for the heat from the heater. Also check the bottle for bubbles. Do not let the engine over heat.

If the car is air locked...

Start it up , turn your heat on full blast.Then remove your resevoir cap. Let the car heat up to normal temp , at this point i would check to see if your fan is turning on. If you watch close inside your resevoir it will be bubbles or bubbling, let it run until you have no more air coming out.(no bubbles, if nessesary top off with fluid to the recomended level. Tightnen up your cap ,making sure it is seated properly and IS tight. Then go for a drive see if your still overheating.
