I really need some help and am totally confused, let me explain what happened
I have a vaux astra 1.6 petrol 2000 model
My engine temp always showed around 85c since the time I bought it
My car recently came back from the garage, the stupid mechanic didnt put the jubliee clip properly on radiator pipe which goes to the engine from the radiator..The pipe came off whilst I was driving...Water started to leak rapidly
I was unaware and was driving, I noticed the RPM meter of the car started to fluctuate a bit..I checked the engine temp reading, showed 85C...I thought coil pack must be playing up and i carried on driving..
After 1 min I noticed the car is not running smoothly..I stopped the car..checked the engine reading showed 87c..I opened the Bonet and noticed this burning smell and suddenly from the bottom part of the engine smoke started to come out..I ran and swtiched off the car
I noticed the radiator pipe has come off and all the water leaked..I fixed the pipe filled the radiator with coolant/water...car runs ok
But now i notice my car temp doesnt stays on 85c like before but it stays on 90c..then goes to 93c where the engine fan starts then the temp comes down to 90c..then fluctuates from 88c to 90c and ocassionaly to 93c???
I checked the radiator bottle for any signs of burnt gasket in the water..The result is water is clean no signs of any gasket particles...
However I noticed my oil colour from golden has turned to dark brown with a blackish shade
PS I dont know if this is also related due to above:: I opened the spark plugs and noticed little oil minute drops on the washer of spark plug no 2 which fits inside the engine although the threads and the spark area of the spark plug are totally dry... Before the radiator leak incident when ever I removed this spark plug it was always totally dry???
