MF 6180 Blowing water out

[TrewithickFarm]

My 6180 has started blowing water out of radiator vent when it comes off full power.
Head gasket?

Try a new radiator cap first. Start with cheap option.

I did think that, but i fitted a new rad last year. Possible it came with wrong cap..?

Is she runnin bit warm when workin hard

There was something to do with dissimilar materials on some part of the block (may be thermostat but can't remember) anyway if engine was working hard and not cooled for long enough would spew water out as the part cooled at different rate to surroundings. once everything was cool seal was remade and everything good. Had this with a 1100 series perkins in a 6265.

Our 4370 used to spew water out the odd time when turned of but i think the header tank was to full but dont think 6180 has a header tank

6180 hasnt got a header tank ,,sounds like the cores are fured up and needs a good flush

Not sure as the temp gauge seems to have packed up. going to order a new sensor and a new rad cap. I have put an infra red hear detector gun over the engine and seems to be around 77 - 80 degrees. according to workshop manual cap should release at 82 degrees.

Anyone recommended a good product for cleaning cooling system?

Radiator blocked in the corners? Fan drive slipping? Impeller fell off the water pump shaft inside? You can get a 'sniff tester' in any motor factor, to check radiator for engine fumes.

Have you tried removin the thermostat and runnin her without it for a bit to see hiw she behaves

Cooling system shouldnt need cleaned if you fitted new rad year ago

Does it have a viscous fan coupling. It may be over heating if has lost its ability to adjust to the increase in heat from rad plus less revs from lower engine speed - equals increase in pressure ? or other wise rad cap as already mentioned

When it puts a bit of water out do you fill her up again immediatly. Just thinkin that if radiator was mabe kept inch from full this would allow expansion room and mabe stop it blowin of

 

[wdah/him]

ours generally has 1-1.5 inches of spare room in the rad, if I fill it it overflows never bothered me much but when silage is over or in between cuts when it is doing lighter work for a while I top it up with antifreeze
