What to do if a head gasket fails on a caterpillar C10?
What to do if a head gasket fails on a caterpillar C10?
If a head gasket is the source of the problem this revised cylinder head torque procedure can eliminate repeat head gasket failures on Caterpillar C10 and C12 diesel engines. Replace all cylinder head bolts with p/n 129-3184, reduced shank bolts.
How to eliminate head gasket failures on Cat Diesels?
Q. To eliminate head gasket failures on Cat diesels, how should the heads be torqued? A. Pressurizing the cooling system with the oil pan removed can differentiate between a water pump leak and a cylinder head gasket leak before removing the head.
What kind of tap do you need to clean a Caterpillar engine?
Use an M16 X 2 (8T-3096) bottoming tap to clean the 26 bolt holes in the block to allow the head bolts to produce the correct clamping load. If threads in the cylinder block are damaged, Caterpillar recommends a Heli-coil® insert (p/n 1084-16CN-32) for these engines.
What kind of head gasket bolts do I Need?
Replace all cylinder head bolts with p/n 129-3184, reduced shank bolts. (Jake engines use stud p/n 132-3229). Failure to replace bolts that have corrosion damage may lead to (premature) breakage. Using a straight edge and feeler gauge, check cylinder head/block deck surface for warpage.

What kind of gaskets do caterpillars use?
CTP’s Graphite, Composite and MLS (Multiple Layer Steel) Head Gaskets are designed and manufactured to provide protection against reduced torque loss and shearing loads. Special coatings, and elastomeric sealing beads are applied on most gaskets to ensure proper oil, water and coolant sealing.
