clmbn_n_yakn Posted December 12, 2010 Share Posted December 12, 2010 Everytime i get into 4X4 I loose my coolant leaving me overheating out in the boonies. Anybody have any ideas whats going on ? Its my everyday driver and never have any problems unless in 4 wheel drive. Link to comment Share on other sites More sharing options...
cubastreet Posted December 12, 2010 Share Posted December 12, 2010 I'd say your cooling system is inadequate. Does the electric fan come on? I used to have the same problem with my 81. The fan didn't come on, and crawling around in 4wd not only makes the engine work harder, but because you're not moving fast there's not enough airflow through the radiator. Failing that, make sure the radiator, water pump and thermostat are working as they should. Link to comment Share on other sites More sharing options...
