After years of wanting one, I finally picked up my first lc. It is '91 and definitely a project (I don't think the previous owner ever thought about maintaining or fixing anything on it) but I am enjoying bring in back to its former glory. Anyways, a few weeks ago I took the rig up to the mountains and it started getting hot on a few steep climbs. I replaced the radiator cap (oem), thermostat (oem), and fan clutch (non-oem- toyota guy said they don't carry them anymore). I've taken it out a few times since and the first few trips things seemed to be better, but the outside temp was lower (70's instead of 90's) but on my trip out yesterday she started heating up again. Any ideas? I'm thinking about getting a Aisin fan clutch and seeing if it can move a bit more air than that cheap Napa one. Any help would be greatly appreciated.
