Hi all. First time 4 wheeler owner here, and not the handiest tool in the box. Our machine was well used and needed some work which was done by a local shop who returned it ‘in fine working condition’. We got it back, rode it gently for about 15 minutes (had new top end), and it promptly died. Looked it over and found radiator hose was detached and engine was leaking coolant around head gasket. So back to the shop it went. They said the hose must have blown off because of the overheating, not the other way around, and the overheating was caused by a fan malfunction. Got another new head gasket. Having already blown our budget, they gave us the quick/cheap fix of jumping the fan switch so it would run all the time. Fine. Back home, we fire it up and the fan is running like a champ. We ride for 5 minutes, then jump off to make sure the fan is still running (don’t want to blow another gasket) and sure enough it is not. Back to the shop. Now we have to get a new fan and thermal sensor. All fixed this time, really. Back home, ride for 15 minutes, and everything seems nice and warm but still no fan. Is this normal, or are we risking blowing another gasket? The radiator is 150 at the top, the front of the engine 150-180, and the exhaust header >300. We stopped riding there so as not to do more damage before we figure out what normal is. At what temp or after how long of moderate riding should that fan (on a new temp switch) kick in? Thanks!!!
