Hello, I recently replaced my radiator and coolant and added a temp gauge in my B7100 HST-E and it's still overheating. Has anyone else had this problem? Thought maybe it has air in the system but not sure how to check it.
The new radiator came from Arko tractor parts on Amazon. It did overheat before but I thought it was because it was corroded and all the fins dented and clogged. I looked in it last night and it didn't look like it was moving any. The belt seemed to be tight enough as well.Jacob,
Welcome to the forum =
First, WHERE you get your "NEW" radiator?
Second, it overheated BEFORE the replacement?
When started cold - take top off radiator, what do you see after about a minute?
Ok your not going to see movement like a normal system.The new radiator came from Arko tractor parts on Amazon. It did overheat before but I thought it was because it was corroded and all the fins dented and clogged. I looked in it last night and it didn't look like it was moving any.

Oh okay that's what I was thinking. I put the sensor inline in the upper radiator hose.Ok your not going to see movement like a normal system.
This is a thermosiphon system, so no water pump and no thermostat.
The belt only runs the fan and dynamo.
Fill the radiator to the top let it run for a bit and look for bubbles.
Where did you put the temp gauge?
Mine doesn't have the whistle unfortunately but I could see it spitting air and water out by the cap when it was showing hot on the temp gauge that I added. I didn't try using an infrared gun though.Are you sure it is overheating? Is the whistle going off? Have you used an infrared gun to determine what parts are hotter than others?
Oh okay! I'll check and see. The previous owner had said it ran hot often when he would mow.These engines are known for cracking the heads when they get overheated.
That's why your looking for bubbles in the radiator when it's running.
