I bought my Alto 2006 in 2007 and the A/C was good then, better cooling, no issues. But in 2011, after a brief accident, the car's A/C compressor an radiator was badly damaged. I didn't bother to fix it then for 3 years.
3 years later, in 2014, I repaired it and it was fine except for the heating issue. I live in Lahore, if I go from Johar Town to Wapda Town or Township, it gets heated up quickly. The temperature needle goes above the mid (To the H side). Also it makes a deep whistle noise for few minutes.
I am guessing, its the head gasket?
Thank you.
