Hi All.
I will be beginning to start towing a caravan again, and on my Towing Electrics installation manual, It states I might need to increase the cooling to my car?
Is this correct and what needs fitted?
And What might need upgrading in my Cars software ?

Thanks Colin

Gearbox temps in this country are usually a non issue

The highest I'd ever seen in my own cars was 106 degrees, while climbing the M6 at Shap, with a trailer and RRS on the back, 3300kg in total

If your concerned, slow a little and drop a gear when climbing hills to keep temps a little lower

Thanks For this, I have had 2 previous Range Rovers before and never had an issue, Just wanted to check .
