Overheating?

Postby hoof » Sat May 20, 2006 11:36 am

I mowed with the new cub for the first time today and it really blew a lot of steam out of the overflow. I only mowed about a half hour and it steamed the whole time. I finally quit when it started to steam a little around the cap. When I shut her down it really steamed for about a minute. Is this normal? If not what do i do next?
Thanks,
CHAZ

nope, steam is not normal. if they are overful they will push excess coolant out overflow until it gets about 1 1/4 inch or so below filler neck. first check for trash in radiator fins blocking airflow, then check timing and carb adjsutments. if still a problem, do compression check to see if you have a bad head gasket etc. finally a last resort take radiator to shop to be flushed.
If you are not part of the solution,
you are part of the problem!!!

Not normal.

I would remove the water manifold on the bottom right side of the block. I would flush the block, radiator and radiator base (from the top).

Then I would back flush everything (from the bottom). Do this two or three times until no more crap flushed out.

Next a cleaning with washing soda.

Also, check to see that the radiator fins are clean and not bent up.

It was full when I started, thought maybe it just had to blow off a little extra until it got to the right level, but that wasn't it!

I always look for the simplist cheapest thing first. Well if it was full to start with the other posts will be good places to start from.

I like your idea of checking simple things first.................. I had a similar problem. What I found was that the fins on the radiator were fouled with old grass and dust.

Try blowing shots of compressed air from the fan side of the radiator (tractor not running of course). You may be surprised what all blows out. This solved my overheating problem, amybe it will solve yours.
