Hey guys, thank in advance for reading.
I'm a pretty good home mechanic and done a bunch of upgrades on my 81 fj40... my most recent issue is a simple one and hoping someone out there with a VA A/C can shed some light on!
I have original 2F 81 engine without power steering. Installed my Vintage Air system last year. Read lots of posts and had a few fitment issue, but now working well. Installed per VA recs with compressor and alternator on passenger side of engine with their installation bracket (I've contacted VA and got no reesponse). However, my fan belt continues to slip despite alternator being at max tightening. I've gone to Napa and previously tried the next size belt down (mine is a 25-9590, I think 58.7 inch), but couldn't get the next size belt to fit. Belt is very tight but the issue seems to be the compressor is at the 10 o'clock position compared to the fan/waterpump pulley and crackshaft pulley is directly under the waterpump/fan pulley.(picture shows config) So the fan/waterpump pulley only has about 2 inches of contact with the belt. I can turn the fan with my hand and make it slip while the engine is off!
Anyone added a tensioner pulley or added a second belt from crankshaft to waterpump/fan? My last resort would be to just remove the fan and replace with an electrical fan but hoping someone else has some ideas.
