Hi could you please direct to me where I could find the engine number? and also tell me if there is anything that looks wrong? I don't know much about engines so any info would be great! I've also been getting the coolant leak problem, it seems alot of people have the same problem but my 7 only leaks when its hot.

I replaced the taps and check if the coolant fizzles... it does but little bubbles not big ones... What could be the problem? (and sorry for my english im from south america)
