Just FYI for anyone driving a pre-2000 Catera...
My '99 had an oil cooler leak at 52,000. This cooler is located under the intake manifold and is water cooled. It looks like a small radiator. When this unit gets even hariline cracks, the engine's oil gets sucked into the radiator / coolant system. Luckily, I was able to shut mine down immediately and have it serviced (as soon as engine oil light came on). The coolant overflow tank was oozing what looked like hot carmel. :mad: The oil cooler is a $250 part, but you will be out of at least a grand after the installation, thermostat replacement, gaskets / seals, and flushing.
This happened due to corrosion on the oil cooler. Please flush your Catera's coolant system and add a PH balance additive to the new fluid. This will save you from a costly repair.
