- 2008 Lucerne
2008 Lucerne 177K miles. In excellent condition. I stay on top of maintenance with the help of a great mechanic. Chronic problem with water pump coolant elbows. Replaced 5 times in the approx 5 years I have owned the car. I’ve researched and think I understand the issue. All replacements have been the metal elbows. Leaking again. Any recommendations? Particular brand of replacement elbow with most reliable o-ring seals?
