OIL HOUSE TIP: Blue RTV is a fantastic all-rounder. However, for a professional “factory look,” many mechanics prefer Blue for cooling system parts (like water pumps) and Black or Grey for engine casing. Always allow the bead to sit for about 10 minutes before tightening the bolts to “finger tight,” then finish tightening after an hour for the best results.
