I'm looking for advice bustedknuckles I just replaced my 105C thermostat with a "95C" thermostat to improve engine longevity.

I'm planning on taking the X5 to Banff next September about 2400 miles 1 way from Houston. I plan to tow my travel trailer, so I'll be putting considerable stress on my 2008 N62 X5 with 96K miles.

I was thinking of doing a cooling system refresh before the trip to ensure reliability while I still have cool weather in houston. What parts should I consider replacing? My X5 does not look to have its original water pump or upper radiator hose, so some parts have been replaced.

I've personally replaced the thermostat, heater control valve and radiator cap (still 2 bar). I've ordered a new expansion tank....

Do you think I should preventatively replace anything else before this road trip?
