Engine Oil in Coolant For
1995-2000 Saab 2.5 & 3.0L Engines
The AERA Technical Committee offers the following information regarding engine oil in the coolant on 1995-2000 Saab 2.5 & 3.0L engines. This addition of oil to the cooling system often causes engine overheating as it reduces the effectiveness of the system. Excessive crankcase engine oil level reduction may also cause engine damage. Vehicle owners adding oil or experiencing higher than normal coolant temperatures should investigate to reasons why.
The cause of engine oil entering the coolant in most instances has been a faulty engine oil cooler, located underneath the intake manifold. In some cases, vehicle owners did not even realize the engine used an oil cooler.
Replacement oil cooler can be purchased from the dealer under Part #4770988. The washers used to seal the plumbing to and from the oil cooler should also be replace with Part #4620324. Those washers are steel with a rubber inner seal; previous washers were a copper design.
