CATERPILLAR-EX-MANIFOLD-BOLT

278-0361 is an exhaust manifold bolt for Caterpillar engines, built to handle the heat cycling this fastener sees every time the engine starts and stops. These bolts are prone to seizing in the manifold threads over years of service, and a fastener that shears during removal turns a straightforward manifold job into an extraction job — worth working penetrating oil into old bolts before attempting removal rather than forcing them.
