Had my first overheat issue today
Was heading up a steep hill in Queenland australia (was about 30c).
Carefully monitoring my OBD gauge as well as temp gauge and saw engine climb to 110C. The gauge got to about 3/4 but was flicking up and down to its usual spot just below half. The OBD temp was flicking between 110 and 103C. When i go to the top it started to boil over.
Got a tow home and bled the cooling system and things seem settled again. Issue seems fine on freeway just comes up in traffic or big hills.
Things I have been observing
- I had noticed this flicking of temp previously. I re-bled the cooling system a week ago thinking I might have air. There was a little that came out but not much.
- The oil filler puffs smoke when you rev the engine. like its the oil breather isnt working? - i have had some weeping of oil out of the filler over the last month.
- There is no indication of water in oil or oil in water.
This car has had 2 head gaskets done before me - really dont want it to be this again.
If it continues I will take it back to my MG mechanic - fixing these MGs are expensive over here so would happy to hear anything I could check before hand.
