I need some help please.
I have a CGA3 (coilpack 1.4) paired with a CG10 gearbox, clutch and flywheel.
It was running fine on the CG10 ECU for around 3 days. Then I left the car alone for a month and then came back. I did one journey and then the next day, I checked the coolant level and the expansion tank was completely empty.
I topped it to max, which only took about 200ml which I found very weird.
I continued to drive it for the next 2 days, temp gauge all fine. Yesterday I swapped the 1.4 ECU into it.
Now today, I drove it a little bit hard and then heard a boiling sound underneath the hood. I opened bonnet to see the coolant was right at the top of the expansion tank and boiling violently. Temp gauge was still reading fine!
Why is this happening? I recently got a drive belt changed, could this have anything to do with it or is it the ECU? Or the fact the performance of the car now outmatches the cooling system? Could it be the water pump or I drove it too hard?
After letting the car cool down, I have checked it again and the expansion tank is completely empty again! but no coolant had leaked out anywhere.
Please help me people.
