Hi Gang,
Several weeks ago I posted a " loosing coolant thread "
Thank you to everyone that responded.
I have since removed the Entire EGR system hoping that would cure the water leak and
also I just wanted it gone. I did the Weeks stage 1 and Stage 2.
to my dismay.......It wasn't the EGR system. I'm still loosing coolant.
The " add " coolant light comes on at just over 150 miles or so.
Suggestions please... Where to look.. What tests ??
Also note : its just got water in it. So also on a side note:
Whats the normal operating temp for a CRD. I have a Scan Gauge connected to the
OBDII connector. I have yet to see more that around 163 degrees on a 100 degree day with the
Air conditioning running.
Ok..back to the water leak.. I'm wondering if there might be some kind of fluorescent dye I could add to the water that would show up with a black light .
I had a can of leak stop once for an Air Conditioning system that had some kind of dye that would light up with a black light after dark. maybe something like that for water leaks ??
Thanks much
Clancy
Normal temperature for a Jeep CRD is 176 degrees F.
see picture belowYes there is UV dye available for the coolant at most auto parts stores. But it is only good if you are leaking coolant somewhere.
IF you are loosing coolant and see no leaks or drips anywhere, you may have a head gasket leak. Coolant is being consumed in combustion chamber and going out exhaust pipe.
Test for HG leak:Engine at ambient temperature after setting overnight.
Remove coolant reservoir cap to ensure no pressure or vacuum is present and reinstall coolant reservoir cap.
Start engine and let it idle for about 30 to 40 seconds.
Open coolant tank cap and listen to hear if any pressure build up in tank was present.
If you hear pressure escaping when you remove cap, you have a head gasket leak or worse yet a cracked head.
