When you say it’s overheating can you please be a bit more specific?
Is just the fan coming on and staying on? (mine does in traffic), or is it actually boiling over and you’re losing coolant? What is the temp gauge reading?
I have a Mulfab radiator, and have wired in an over-ride switch so I can bring the fan on a little earlier, like when entering a built up area, and have just fitted a pair of bonnet catch extensions. Mine doesn’t lose any coolant and we often have 30+ degrees here.
