It's 35 bucks for a mechanical fan clutch. That will ensure you don't get creep at idle and low speed. 210 is not unreasonable though.
It's always a bit of effort to get into 4Lo - rolling barely, pop the trans into N, pull back firmly from 4hi into 4lo - expect a bit of gear noise or resistance and it will firmly engage, put trans back into D. That is common.
Last 2 years of XJ's have a temperamental head that will not tolerate overheats. Keep a very close eye on the coolant reservoir, and oil dipstick/oil cap for cross contamination. This is not a scare tactic, but if you maintain your cooling system you will likely NEVER have an issue. Keep the rad and condenser clean of junk/mud/bugs, replace the serp, hoses, water pump, coolant, rad cap, and tstat every 2 years and you will be fine.
Start oiling the body - it will start to rot the rockers first.
If the windows only go up and down at times from the drivers door, then you need to bypass the lockout switch.
White XJ's are the cats azz.
