Hi all
1.6 engine.
Head was rebuilt 1 year ago, thermostat changed.
Today it overheat on idle to the max. some coolant came out the lower hose because of the pressure.
Both of the cooling hoses were hot, and fan was working (only 1 fan speed).
I let it cool down, opened the bleed valves and then filled coolant.
Almost 2 ltr was missing! ALTHOUGH coolant level was on MAX in the radiator!
I then started the engine with the radiator cap off
BUT, when I did that, coolant runs freely when the rad cap is open, and then I loss much coolant.
I closed the cap when I saw that, and then fan kicked in normally at half temp.
My question is why if I start the engine with rad cap off, the coolant doesn't stay at it's height, and wants to get out?
On all of my puntos when I did that, coolant didn't want to get out so quick and I waited until fan kicks in with the cap open.
Compression test is fine, about 170-180 on all cylinders.
