Hello together, during the last summer vacation I had to find out unfortunately that the cooling performance of my Omega with residential trailer is quite overburdened. It probably means that Opel had built in a reinforced cooler in the 2.2 with standard trailer coupling and automatic transmission, because it costs at the FOH however to the 400,- € and I am not clear whether this statement is true at all and above all, whether it fits at all, that is a bit too risky for me. the question me whether you can increase the cooling capacity in other ways (assembly further fans, cooler of another model)? Do you have any ideas for this?
