Asked by Aug 28, 2015 at 06:52 AM about the 1990 Opel Corsa

Question type: General

The green coolant/antifreeze in the car  was clean and clear.
But while i was connecting new hose coupler(attached photo)between two cooling hoses(in order to build a
shape of hose that i didn't find in the stores)i was creating some rubber particles in the hoses(that was made
from the pushing action of the hose coupler into the hoses).
I forgot to wash the final made hose and i connected it back to the car,but while i added fresh anti freeze i saw
some rubber particles in the expansion tank and now they are flowing in the cooling system.
My question:May these rubber particles in the cooling system be a problem?
The coolant is new and all the system was clean.There are only those rubber particles that made by me,since i
forgot to wash the inside of the hose before connecting them back.
And i really would like to avoid making flush to the system just because of that(as i mentioned,the coolant was
new and clear before)if it may not be an issue.

Thanks in advance.

when you say some, do you mean just a few pieces? how big are the pieces? I'm assuming small because they flowed thru the cooling system to get in the tank. If there are not many and they are small, I would think it would be ok. But if there is allot and the pieces are bigger they could clog the cooling system. To be on the safe side I would flush the system out again..


do like joemom said...... better safe than sorry

I made this hose to replace the hose that connected between the expansion tank and a metal flange ,so the particles were not need to flow through the system cause they were close to the tank from the beginning. When i add coolant to the expantion tank,it was washed the inside of the hose and the rubber particles,that were washed from the hose could be seen at the expantion tank. Now,after the car was driving some miles,the rubber particles are slowly disappeared from the tank. I don't know what is considered big and what is considered many. This is the reason that i attached the photo,in order that you can estimate,from your experience,how much particles,could be released when doing this fitting on the hoses(btw the hose coupler is connected between an old hose and new hose,so most of the particles,i guess,come from the old one). Is there any checking method to know,if these amount of rubber particles could be a problem or not?


that little bid should not cause any concern.
