Massey Ferguson1010 3 cyl diesel overheating

[johnnyo34]

I have a little MF 3 cylinder diesel.. As soon as I run it for awhile it blows antifreeze out the overflow tube. thinking maybe thermostat is stuck, I took it out..
Still does it...so I replaced the water pump, still did it..
no bubbles in the rad, no antifreeze in the oil, and no white smoke in the exhaust, no oil in rad... I took the rad in to be cleaned but haven't put it back on yet. The rad shop said it was 30% blocked inside and 25% blocked outside.. would that blockage be enough to cause my overheating??
When I put the rad back on and it still does it do I look at a blown head gasket???
thanks in advance

Check your water pump

Oh sorry I forgot to put that in my original post. I added it now. I put a new water pump on it. but that didn't fix it
One thing I should mention is when I took off the rad cap with the old pump I didn't see the coolant moving leading me to think the pump was bad. but when I put the new pump on I still don't see the coolant moving{circulating}

Start checking the hoses to see if any are collapsing. Over time hoses can lose rigidity and collapse, creating a blockage in the system. Male sure the pump is engaging and the belt is not slipping. Last thing you and do is try and drain and flush your cooling systems to make sure there are no clogs or buildup

I would try and flush out the block seeing you already had the radiator work done....

I have the hoses off and they look good. of course when I took the rad off the system pretty much drained.
What is the best method for flushing the system. WE are around zero degrees with lots of snow. I only have a carport to work in.

can you recommend any flushing stuff to use??

I use a garden hose but your outside in the cold IDK......That's a tough one..

Is there some kind of stuff I can add to the cooling system then run it and drain it again?

The problem is if there's a clog or blockage an additive won't make it around the system. The garden hose is more a test for fluids going through than it is for any cleaning .


Adding a radiator system flush to a system that already isn't circulating correctly doesn't likely fix the issue.
