over heating E200 1988?

[Ramy Z]

my dad has a 1988 E200 and it's always over heating while stuck in traffic not necessarily overheating, just passing the 80 degrees Celsius mark and my dad doesn't like that, so he mostly drives without the AC which increases the overheating, making the car unbearable in the Egyptian summer heat.

it's made in Germany though, most likely it's the reason

but my question is what can be done about that ? Or is that just normal ?
