Yes I do have a breather tank, but the guys at the workshop took care of the instalation, they used an e'spec brand T-joint, I'll go take a closer look under the hood if it mentions anything about size...

dammit, didn;t take a picture, but it looks very much like the one you posted. And it has a big 30MM on the side, I think that's a hint

so how is this any different than the reservoir??? sorry for the stupid question i just don't see the benefit of it.

The function of these is basically to collect bubbles that may form in the cooling liquid, to prevent them from recirculating, which improves cooling efficiency. Probably most effective under heavy loads or long drives.

humm ok.

how are bubbles gonna form in a closed system? the only way is incorect bleeding... only the coolant starts to boil which will be almost impossible in a good runing system.

Thats pretty much useless. Bubbles dont form in a closed system as stated above. Also if its hooked up as shown in your diagram, water will bypass the radiator.

Indeed!

On top of it being useless you are going to drain the coolant back into the lower radiator hose through a guage sensor port?

eTiMaGo · 05-03-2007, 08:40 AM

it's.... it's.... it's japanese so it must be good!

But is the engine cooling system really always a completely air-free, perfectly closed loop?

If you had an air bubble your car would overheat.

well it will make the needle(or light) go to hot/on since the steam is hotter than the coolant, and then it will drop once it passes. still not good for your car. but that would only form from a leak or bad bleeding.

Brings back horrible memories of my aw11... what a biatch to get all the air bubbles out. We should all be thankful that the rad is on the same side of the car as the motor in the yaris.

Depends on how big the air bubble was. If it is big enough, Water won't flow at all.

There are no bubbles to be reduced. If you have bubbles the system is not full or properly bled. All that thing does is let coolant bypass the radiator to provide less then max cooling.
