I’ve had difficulty in locating intake manifold kits for GM 3.8L engines. What gives?

Click Here to Read More

The AERA Technical Committee offers the following information regarding a revised upper intake manifold for 1995-2004 GM 3.8L VIN K engines. Engines manufactured for the 2005 model year include the revised gasket.

With the recent availability of these new kits (Figure 1) it provides the dealer with a much greater ability to get exactly what is necessary for a proper repair. Previously, parts may not have been available in desired quantities, which delayed repair. In addition to better availability, some of the gaskets have been updated to a more robust design for greater durability.

I’ve had some crankshaft damper bolts back out on the Hyundai 2.4L engine. Any solutions?

The AERA Technical Committee offers the following information regarding a revised crankshaft damper bolt for 1999-2005 Hyundai 2.4L VIN S engines. Along with the revised bolt, the torque value for new and old bolts has also changed.


The torque specification for the 2.4L engine crankshaft damper mounting bolt in Santa Fe and Sonata vehicles has changed. The new torque specification is 116-123 ft.lbs. (157-167 Nm). The previous torque value was significantly less and on occasion it would loosen during normal engine operation. All 2.4L engines built on or after May 28, 2002 are torqued to the new, higher torque value at the factory.

Note: Engines built prior to May 28, 2002 can be torqued to the new value without replacing the bolt. The revised bolt part number did not change and is available with p/n 23127-38000 (Figure 2). Before re-using a crankshaft damper mounting bolt, inspect the bolt for pitting, corrosion and damaged threads. Replace the bolt if there is any question to the condition of the bolt.
