This message is a Question subject matter of an archived post. I am trying to reactivate this thread for IH 504 utility w/ D188 Diesel head gasket, and oil passage/water seal inserts, showing "failing inserts from coolant passages" Posted by 1370rod on January 21, 2015.
Having recently acquired a 504 utility w/ D188 due to exhaust "spewing out green coolant" after trying to start by past owner when tractor sat through the "Record Term (2 weeks) of below freezing temps of 17F-25 F degrees F" last January 2018. Since that time PO also found dipstick tube filled to top with what looks like water, which I assume is coolant.
What I am in process of doing is tearing down to determine failure.
During durations of freezing weather it is understood the importance of anti-freeze protective levels. I can only assume it had antifreeze in tractor by spewing out distinguishable green coolant, but freeze protection is unknown/mute point for now.
Does the D188 have a reputation of pushing out water jacket (freeze plugs) in certain areas, such as under valve cover gasket?
I am thinking head gasket let go, since coolant was blown out exhaust upon last cranking attempt and filling crankcase with coolant/water by visual inspection. Trying to work on it Today, but presently 25 degree F, lots of layers to be able to work outside.
