Hello, Have a 94 Grand Cherokee Laredo with Inline 6 engine..I towed my 17 foot 2000 pound boat with loaded up Jeep and A/C on...Jeep towed OK but my temp gauge was unusually high (around 240) to right below "red" mark on gauge...It never over heated and when I am not towing temp seems OK..I say "seems" because when you have A/C on and sitting still it reads around 210 on gauge...I have a friend with same Jeep and he says his does same (around 210)...I'm sorry but this does not seem normal to me.:screwy: .Anyone else???......Thanks,Pete
