Re: 98 grand cherokee limited 5.9 seems to run hot
The fan system is a PITA. Different sensors to control different speeds with combination of 3 relays if I remember correctly. Finding replacement sensors is like pulling teeth. 180 degree is already cooler than stock, stock is 195 IIRC. Another website that might provide you some answers on these is speedfreaks.com. It is a very slow site now, but guys are still checking in occasionally. All my Jeeps have run right around 210, that is normal for them. If you are able to hold steady at around 200 then I would say you are doing good. There are other after market fans you can try and make work but I think you are better off with electric over mechanical on something that will be spending long periods of time revving at low speeds.
