Deere 455 - smell some coolant while operating

[theedudenator]

I cant tell if it is using any coolant.
I really never added any to the overflow bottle.

I get a wiff of smell when I am mowing.

Is there a weep port on the water pump?
Anywhere else I should look.

I do get a puff of white smoke when I start it up, never comes back.
I checked the glow plugs, I have voltage to them.

I replaced my dash gauge assembly, temp gauge is still not working.
Going to try to check it today.

If your water pump is dripping from the weep port, o-ring or gasket you may not see it since it seems to hit the lower pully. Look for white areas of dried coolant.

My X748 had a leak in the lower radiator pan. Replaced radiator. Now the water pump is dripping. That will have to be replaces soon I guess.

If your not loosing coolant then its just coolant bottle venting the odor as warm coolant goes in it as the engine heats up. I get the same thing on my 3320 tractor.

If it were me, I would pressure check the Radiator. This would determine, if you have a leak, and where the leak is. Perhaps your local Advance Auto will loan you the pressure tester by making a returnable deposit?
