got a few issues i think there's a blockage in water system ive flushed a few times each time crud comes out there's a lot of corrosion and ive replace water pump an thermostat. when i got it you couldn't drive for more than ten mins it would blow all water out since replacing pump n thermostat is alot better tho intermittent hot and cold will drive in low off road all day and blow nice hot air get bk on road over 50mph temp will go up then come down if slow down odd i know i think its had a head or head work done but she runs spot on no missing
