ICS 8.3 Coolant Filter Valve Stuck

[JellyBean]

Preparing to change out the filter and have read about how easy it is to break the valve. Since I have already changed the oil filter access is limited to the backside of the valve.

Questions....


1) Does the valve rotate either direction?
2) Is there a wrench size for the backside of the valve? To make A long handled tool.
3) Vacuum on the system to limit drainage during filter exchange?
4) Just do it quickly and deal with the mess?
5) Suggestions welcome!

Hi JellyBean; Try watching this UTube video.

Shows him replacing the coolant filter. Also show him turning the coolant shut off valve. Reaching up from the bottom he turns the shut off valve clockwise just 90 degrees.

Thanks!

I watched that the yesterday but didn't catch the direction the first time as his hand is blocking. Watching again I can see his thumb turn the valve's direction. Looks like I will need to make 2 wrenches. One short to start the turn (between the filters) and another to complete the turn to shut it off.

Maybe I will get lucky and just starting the motion will free up the valve so's it will turn by hand.

I read at least three posts describing how easily it is to break the valve by using force on the "handle" side. The recommendation was to turn the valve on the inside between the filters. When the oil filter is off there is room to access that side.

Waiting on the Air Filter and AC belt to arrive before I change the Coolant Filter; but I guess the gives me time to test out freeing my stuck valve.


Thanks again for posting the video. Made me take a second look!

Do you have the Cummins QuickServe Online for your engine? If not, you can sign up with your engine serial # on this link:

I was looking at the same issue some time ago. For my ISL 400, I found the below info. There is a valve handle on each side that connects to the same shaft.

If that's the same on all Cummins engines, I can see why those valves can be broken by trying to turn the wrong way. One closes clockwise, the other side CCW.

Just signed up yesterday. Thanks for the image!

Yes, I agree it is easy to try to turn these the wrong way; especially looking at the right side of the valve. The side between the filters shows the "stop" block and it is easy to see it only turns one way. But you can't see that from the bottom when lying on the ground....

Looking in from the top side I used a wrench and it turned freely! From there it was simple!

Another day / Another $1.95.....

Hi JellyBean; Glad all worked out and the valve was not frozen! I got a raise up to $2.00!

I didn't have to worry about breaking the shut off valve. , as it didn't know it was there until I had filter off. Hey look that's a good idea. i believe I did operate it and it turned by hand. I did still think is was two valves until now , I probably closed and opened both sides of same valve, hey they both work.

Great to flush engine with water as part of the practice. I have used distilled water for both the flush and to add to antifreeze for the last 20 years. Critical with aluminum components, probably a good idea to keep chlorine and minerals from tap water out of the radiator.
