sandmann Posted November 9, 2013 Report Share Posted November 9, 2013 (edited) My banshee has been driving me crazy for a while now. Its been overheating after running for about 30 minutes in the sand. The coolant gets very hot and starts going out the overflow valve on top of the radiator and drips down on the exhaust through the connected hose. To try and solve the issue I did the following: 1- installed new head gasket (installed properly with 20 lb.ft of torque) 2- installed new radiator cap 3- installed new water pump propeller (stock) 4- flushed cooling system and used new coolant 5- changed gear oil 6- tried different fuel mixes All the above did not change anything. Banshee still overheats and coolant starts shooting out the overflow valve. Other than the overheat, the banshee works perfectly and starts from first kick. My banshee is a 2004 100% stock, no modifications what so ever. Its very well maintained. I need some professional help guys!

sandmann Posted November 9, 2013 Author Report Share Posted November 9, 2013 Air filter is clean. And water pump gear is ok, I opened up the cover and checked it. As for the jets, its stock. I didn't change anything since I bought it. Just kept it maintained. Quote Link to comment Share on other sites More sharing options...
Tech AS Posted November 12, 2013 Report Share Posted November 12, 2013 Just throwing this out there. Have cleaned your radiator lately? Dirt can clog up the small space between the fins and greatly reduce the cooling efficiency of the radiator. Quote Link to comment Share on other sites More sharing options...

Rustbag Posted November 12, 2013 Report Share Posted November 12, 2013 Sounds like you have an air leak. You MUST do a leak down test if you wanna fix it. Could be seals or reed cages leaking. Do a search for leak down test. Mine used to do that before I finally took the forums advice. I repeat, leak down test. Quote Link to comment Share on other sites More sharing options...
