VW Overheating

The easiest cheapest way out? Do what VW did cut a section of deck lid out behind the license plate. The next thing I’d try would be tennis ball. The last thing would be stand offs.

The doghouse cooling system is the one to have I use it on everything unless it’s car show 100% stock. A couple of years ago I built a 64 bug running 1600 w/doggy house. Only ran over warm on hot days, stop and go traffic or pushing hard.

You could also go with a convertible deck lid and that looks nice
