Hi guys

Quick question on overheating..

2013 GU overheating, took it to Nissan - one new radiator (radiator was blocked as hell, had mixed coolants etc) and thermostat later and the car is still overheating - this time on hills and in particular as soon as you turn on the aircon (even when you quickly turn it off is stays hot). If I keep the car on the straights and not push it hard it doesn't overheat - as soon as I switch on the aircon or give it a bit on a hill it overheats immediately.

Nissan are adamant the cooling system etc is perfect. They did say that my shroud has parts missing and or/broken off, which they have ordered and will be fixed tomorrow.

Question is - can parts missing off the shroud cause these overheating issues? I'm not totally convinced and it's going to cost me $800 with labour. Help! Any advice would be great.

Cheers
Damo
