If the coolant is dirty, that usually means it's old..........how old are the other cooling system components?

 

Rigs a '91 soooooo......... Lady that had it before me toom pretty good care of it. But who knows.

 

Took

 

Not. Dirty coolant is a good indicator of lack of/poor maintenance/neglect. Might want to start checking things/fluids/maintenance items bumper-2-bumper.

 

True that. Thx guys. Will figure out how to flush and do it tomorrow. Let ya know.

 

Some cooling system components could be 20 years old.......a ticking time bomb. +/-$250 in parts will replace all the cooling system components, including the radiator. T-stat (it's cover), water pump, fan clutch, head/block flush are really easy to get to and do when the old rad is out. Replacing cooling parts one at a time is really a hassle 'cause u have to drain coolant each time u change one part. Change 'em all and be done with it.....summer time temps are just around the corner.

 

Flushed and new tstat. Temps holding 190-210. When should my fan kick on? Seems like its only coming on when i turn heater on. Havnt run for extended period yet though. Was around 210 then i turned on heat and fan came on. O.o

 

Any ideas?

 

fan kicks on at 218 IIRC. also kicks on when the a/c compressor is engaged (are your switches on defrost mode?)

 

my $.02, replace the radiator cap also.

 

Is it normal for temps to be a little higher when towing???

 

Define "a little higher". Ambient temps?

 

220 ish. 70 outside. Towing a 3 1/2 ton van back to our church. Towed about 3 miles.

 

My, my, that's a tail waggin' a dog. I'd say you're ok, wouldn't make a habit of it though.

 

jesus, that's a bit of a heavy load for the XJ to pull.

not too bad of a temp though
