Engine News SEBD9724, 23 August 2011, "Introduction of Radiator Protection Screen on C4.4 and C4.4 (Mech) Engines". Disregard this article. See the replacement article that follows.

There have been a number of isolated instances of issues with radiators in severe service applications. These issues are that debris is entering the core of the radiator. This debris can cause the core of the radiator to erode.

A new 372-8150 Radiator As has been introduced that contains a protection screen as part of the assembly. The radiator protection screen increases the protection of the radiator cores in severe service applications.

The protection screen would be installed in harsh environments only, the original assembly is still available where the protection screen is not needed.

In certain instances if the application is suffering from premature wear of the radiator core, then 372-8150 Radiator As can be obtained to replace 236-7766 Radiator As .

The new radiator assembly can be installed when the current configuration is 111-5767 Fan and 236-7766 Radiator As in combination.
