Airlock on bypass pipe

seem to have a airlock on my drivers side turbo bypass water pipe, when the cars up to temp and you switch the ignition off, you can hear it bubbling any ideas how to get it cleared. i cant take the pipe off and fill with water as all it does is leak out of the pipe it connects too.

You wont clear that probaly,thats pure heat overcoming the engines cooling system and cooking the coolant in the pipe after the engine is turned off.Id look at why the engines running so hot to cause that.

Maybe an air leak somewhere on drivers side letting in slight amounts of air?

 

Has your coolant dropped any?

 

When i refilled mine it took nearly 14L before I managed to get all the air out and then the next day I undid the bleed screw a little and air was still hissing out. I just left it open until the hissing stopped. I've looked again for trapped air that way but so far it seems to be good and hasn't built up again.

 

just an idea mate.

its supposed to be 10litres for the coolant system, but yeah im finding im still topping it up, yet no wet spots under the car. so must still have air in the system some where, i do get hot air in the cabin when i put the temp up through the system, and i had the front raised when putting the coolant in to start with.

 

I do have a strange bearing noise from the water pump area, im just wondering if my thermos is opening or not when it comes up to temp.

You could try putting the car on ramps at the front, supposed to help air make it's way to the top point of the system (bleed screw) easier.

 

Can't say about the thermostat, but if your wondering then it may be best to get it off and test it to see if it's opening.

will do that after JAE, cars running quite good at the moment, all cylinders firing, smooth idle, holding its temp.

 

Bit sluggish though like the turbos aren't kicking in, though could be due to the Auto box on manual turbos. so not sure, considering it doesnt bloody change gear like its supposed to.
