BX1850 Radiator Boiling Problem?

[Ethanflux]

I just bought this BX1850 used. Is it normal for the fluid in the reservoir to be boiling? It doesn't seem right to me.

You didn't mention the temperature gauge so I am assuming it was in the normal range. Check the radiator if the the radiator isn't or wasn't full, the air in the radiator would be purging out through the overflow tank when the engine heats up. When it cools it will pull coolant back into the radiator and the level in the overflow tank will go down. If you have to add coolant be sure to add one that is compatible with the present coolant.

The needle does read high and does barely go into the red. I wouldn't say that it is bubbling from air pockets but because the radiator fluid is actually boiling hot.

more than likely bubbling from a leaking head gasket. You will need to pressure test the system to verify/deny.

Since it is getting hot check the fan and the screen in front of the radiator. I don't know about a BX1850, but on my BX2370 with the hood open you pull the screen up from behind the radiator.

Like Larry said, open the hood and back by the hood latch you will see a little tab sticking up by the radiator. Pull the screen out and check it. If it is real dirty at the bottom be sure to clean the bottom of the radiator out to.
