Diesel leaking into Coolant?
Is it possible for Diesel fuel to leak into the Cooling system in the D24 NA engine?
I added dye to my fuel to trace a leak on my injection pump,
While shining the UV light, I noticed a leak on the block coolant sensor, which I apparently did not fully tighten the other week
I am using a green coolant, but it seemed more fluorescent under the UV than it should’ve been.
Also of note….my wagon does suffer poorer fuel economy and higher engine temperatures (compared to my other 2 diesels)
After some quick research, it would appear that the issue with other diesel engines could be with the “Injector Sleeves/Cups?”
Does the D24 have these?

Reason: better wording
