I hope not.

There isn't any blowby and the coolant isn't boiling over.

I haven't driven it on a long trip since installing the new fan clutch but when I drove it over long periods about 90 mph the heat would get up there close to 120C when running the A/C.

Outside temps were over 100F at the time.

Since installing the new fan clutch it will get pretty hot when idling.

I tested the fan by jumping the contacts on the sensor on the top radiator hose and it spins like crazy when I do that.

I'm still not sure what the hell is keeping the electric fan from coming on but I really need to get it sorted out.

I know that in the recent past it was working but since I blew the fuse I haven't witnessed it coming on.

Something's wrong and I think it could be the alternator/electrical.

There are too many warning lights popping up for no apparent reason.
