When I start up the car and drive away I can hear this squeaky gurgling noise coming from in front of the instrument panel as the revs rise. Kind of sounds like there is a nest of young birds there twittering away. :shake

Now I have looked and there is not a nest there! I have also checked the coolant level and it is also fine.

The water pump and thermostat were changed two weeks ago and this noise has been there ever since.

I took it that there may be an airlock in the system so i ran the engine with the cap off the header tank. I got a couple of bubbles rising but nothing major. I have even tried this with the heaters on full blast so as to make sure the coolant had full circulation.

Anyone any ideas on either what might be causing this noise of how to solve it?

I don't think so as I have listened to it from under the bonnet and there is not a sound from the cover. It is more in the bulkhead area. The last time I heard it was when it was low on coolant!

Was the water pump that was fitted new or Second hand?

i would say water pump without a doubt we had the same and when the head was worked on the water pump fell to pieces as it was removed
turned out the bearings were what was making the noise

Could it be something to do with the heater matrix then? If it's coming from the bulkhead...?

Getting coolant in the passenger footwell?

This is what I was thinking. No coolant in the footwells - not that I can see anyway!

Sounds like air in the cooling system run it up to operating temp with the cap removed and until the fan kicks in then rev it a bit constant revs at about 1500 not large amounts this should get rid of any air. Keep the system topped up. if you are happy all air is out let cool down a bit and top up.
