mnkyboy Posted October 19, 2009 Share Posted October 19, 2009 make sure the cap on the coolant bottle is sealing,ive seen several were the the cap doesnt seal and they would overheat at idle. Link to comment Share on other sites More sharing options...

xmeatbagx Posted October 19, 2009 Author Share Posted October 19, 2009 No shroud, no e-fan <-- i was planning on putting one in but anything involving wires confuses me lol Link to comment Share on other sites More sharing options...
Eagle Posted October 19, 2009 Share Posted October 19, 2009 Replace the viscous fan clutch, and get a shroud. Link to comment Share on other sites More sharing options...
xmeatbagx Posted October 19, 2009 Author Share Posted October 19, 2009 Alright, so I'm gonna pick up a new fan cluth, I think I have a shroud and an e-fan in the attic. If I don't have a e-fan in the truck already would the plug be there or am I gonna have to cut and splice wires? I figure I might as well do everything and have alittle back up cooling. :brows: Thanks, Sean Link to comment Share on other sites More sharing options...
