want to take the whole shroud off to drain and clean radiator and block. can not see any other way to get the bolt out of block and lower hose
On the front of the BX, where the hood hinges, you'll find two black plastic grips that you can loosen. Take them out, if you wish. They are design to be tightened by hand. I found if you closed the hood, ever so slightly, the surround pulled out the front easily.
BTW, if you have the front grill guard on, it is in the way, obviously. It will need to be removed first.
With the side curtain panels removed, the engine is exposed in all its glory.
If I recall, in addition to removing the grill guard, I had to raise the loader in order to pull the engine cover off...it's a pretty simple procedure. FWIW, I didcovered that I can remove the oil filter without taking the engine cove off.
