Last week i was on motorway when my car heated up and made me suffferrr alot on the way to abbotabad from lahore. Befire that I got my Radiator checked flushed with acid(slightly) and reinstalled. In abbotabad the radiator walas guided me that first of all get a new radiator cap and then look for another problem.
I went to Toyota Abbot motors and told the Guy my opinion. The guy just took a cap off a Corolla Xli standing there and tried on my Platz, and we went for a ride. I changed it and went to naran and back to lahore, alhamdolillah without any heating up.
So it was only a Cap that caused me so much trouble,
