GL 450 towing equipment




Looks like the first order of business will be to add the transmission cooler.
Edit: That big radiator in the front is the intercooler for diesel models, which makes sense. It also means there's plenty of space to add additional coolers if necessary.

Your GL owners manual says go tow up to 7500 pounds. It contains no cautions or requirements for special equipment. … because none are necessary and none are available because your GL is ready to tow that 7500 pounds if you have the trailer hitch. You could tow that 7500 pounds all 4 years/50,000 miles of your original warranty and never hear anything from Mercedes that “you didn’t add a cooler” or something else equally ridiculous. The trailer hitch on my GL was dealer installed and there was no attempt to sell me any extras.
You will, btw, need to get electricity to that trailer the Mercedes way … no scotchloks, no “tapping in.”
merikun folk knowledge doesn’t apply to Mercedes.

Also, it appears that if it didn't have the trailer package, it didn't have the secondary transmission cooler. There is the primary transmission cooler that is part of the main radiator, but the secondary one is an add on that probably only comes with the trailer package. Or maybe it was standard on X164 models but not W251 and W164.
