Good morning,

I’m chasing a engine coolant leak. 

I believe it might be coming from a recently changed coolant filter. The filter feels tight. Yesterday I’ve cleaned the area so I can see the slobbering coolant leak a little better. The coolant is hitting the case and drips and runs down on a oil pan mounting bolt area and then runs along the pan/block seam. 

Engine work (head removal) was completed last week which compounds the issue but I believe it is coming from or near the filter. 

The filter mount and supply/return hoses has shutoff valves for filter replacement.

My question:

For troubleshooting purposes can I temporarily shut off coolant flow to filter and run the engine for a short period of time?

If the coolant “slobbering” stops I’ll pull the filter and inspect the seal and mating surface. 

If that’s not it... I’ll keep digging. 

Help is appreciated!

Thanks, JK

Do not run the engine with the coolant filter remote mount valves shut off.  They are there so you can change the filter without taking a coolant shower.  The first thing I would do is dry everything around the valves and then see if they are leaking.  Second, the filters are cheap & I would change the filter as I made sure the mount was clean.  

Let us know what you find......................

I found a coolant pipe leaking at rubber hose connector above the filter. It had spring type clamp. I’ve added a band clamp. 

I won’t run with filter lines closed. I’m hoping I’ve solved the coolant leak. 

Thanks, JK

I am with Steve. There are two little valves on top of the coolant filter housinf that you shut off when changing the filter. Many times a valve stem on the coolant system will
Weep when moved. Use white paper towels to find the leak. If it is one of the valve stems try tightening the packing gland nut

Took the family for a drive. Coolant leak is solved!!

Good job. You're going to be a great guru!

Coolant leak was on a connector with a spring clamp. I added SS compression clamp.

While I was at it I fixed a few wiring harnesses.

Hmmmmm. Thats the first time i have seen anything BUT constant tension clamps used.

I’m going to replace all of them. I’d like to figure out an easy way to remove the spring clamp without disassembling the coolant system.

when i put new silicon hoses on, i used as many constant tension clamps as would fit. 3 in some places.
