radiator question

Postby made2care » Wed Dec 24, 2014 9:48 am



I'm going to attempt to replace my water pump.From what i can tell, the pump is fine however there is some oil weeping from the weep hole, so thought i might as well replace the pump while I have everything apart. I have carefully examined the "how to" section on this topic and have all the necessary parts .
Quick question. Since I have the radiator off, should i pour a cleaner of some kind in it and let it sit. Is this necessary? What should i use?

You can...but be careful. Don't use anything in any way corrosive. Unless you are actually seeing scale on the inside of the radiator when you remove it, you might be better of doing a simple water flush and leaving it at that.

Okay, I will give it a good water flush then.

If there is minor to moderate scaling inside, you can try using vinegar to clean out the calcium deposits. The acid in vinegar will dissolve calcium, yet is not so strong that it should harm the radiator base metal. If you put a cork of some kind in the outlet and fill with white vinegar, you'll see bubbles rising as the calcium is dissolving. I wouldn't leave it for more than 20-30 minutes, dump and rinse with water several times to clear the trash and vinegar out.

Of course, if a visual inspection doesn't show any build up, plain water is probably as good as anything. If you've got oil in the radiator, you can flush with alcohol.


I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.
