Bora V5 Engine oil mistakenly put in coolant reservoir.

[rcreff]

My younger brother borrowed my vehicle the other day to do about an 80mile round trip. He notice "A light come on" and thought it was the oil light.

He thought he would do me a favour and add some motor oil to the car, bless him! After doing this he carried on and returned home telling me the oil light has continued to flash and beep when I checked this out it was quite obvious it was the coolant light, I think thats what you call it.

He explained what he had done and I quickly responded with a clip round the ear hole.

Please can someone tell me what damage has been done to the car. How do I drain it all out, I dont want to go to a Mechanic do to this my Brother hasnt got a job so I thought I would give him a little task and fix the F***** thing himself maybe he will learn a little about cars. Its a spare vehicle and I would rather not be spending money on it if I dont have to.
