Cooling system enquiry & help needed

[TitanRev]

I'm a bit confused after searching through the net looking for bubble removal tank aka expansion tank and reserve tank.

Ok. at this moment I'm sure of the 2 things is that:
1. expansion tank is a tank for the hot coolant to cool down and to remove the air bubbles in the coolant to avoid hot spot in the cooling system. Correct?
2. The reserve tank is to store extra or excessive coolant and the coolant would be drawn into the radiator when needed.

My questions are:
1. Is expansion tank also known as breather tank?

2.Normally we see that cars only have a reserve tank beside the radiator to store extra coolant and there's no expansion tank. The radiator cap is place on top of the radiator.
Now, my car's radiator cap is at the reserve tank but the reserve tank is pressurized. Is my coolant tank a 2 in 1 type..meaning reserve tank + expansion tank ??

3. Since my original tank is made from hard plastic and the cap is also plastic with some valves on it. The cap is starting to leak coolant when I drive the car hard or during hot weather. Can I buy an aftermarket expansion tank and use it as a reserve tank. With both function of removing bubble and also act as a reserve tank.

Yes, some might say I can just replace the cap but I don't know how long will it last and the reserve tank is made of hard plastic, it very hard to see the coolant level because it's not transparent it's opaque already and the car is 10 years old. fear that the tank might fail during driving.

constructive comments and suggestion is highly appreciated. Thank You.

Y not just swap a aftermarket aluminium radiator since you have mentioned the current were made of hard plastic 10yrs ago? so you can drive at ease? even if you change/add a expansion tank, the 10yr old hard plastic will still not last long under hot weather...

My old E34 radiator is aluminium (i assumed lahor any kind of metal) it have not failed me but the plastic piping burst due to heat and pressure... So to play safe, change all to aftermarket one gua...

Zac, the leaking is not at my radiator but from the reserve tank. I'm still looking for aftermarket radiator but it's not easy to find one.

Oooo... what car is that? so difficult to get aftermarket parts? must be a rare beauty otherwise you won't have mood to entertain it... care to share?

Just suggestion, try change those thing before it's condemned, or else you might facing bigger issue afterwards... a hard-plastic radiator malfunction is just a matter of time... All the best to you and your car...

u could try using forged aluminium radiators & fans.
if cant fit, it could be modified to fit your peugeot.

TR, this is what you need ... surely last longer than the car itself.
