Hello, I posted a question about water pump lube 2 weeks ago. It was in reference to my friend's 1997 F-150 4.6 w/49,500 miles. On Tuesday, July 9, we serviced the vehicle's cooling system; likely for the first time.
The coolant was dark, opaque brown and smelled like a mixture of decaying animal and strong urine. It was disgusting. We diluted the filth using the lower radiator hose as a drain because it cleared solid dirt. During the afternoon I "soaped it up" thrice. Cascade liquid dishwasher detergent the first time, a bottle of NAPA 10 minute radiator flush the second and finished with a caustic powder made by MAC. The powder required premixing and a 20 minute drive. Each step increased the dirtiness of the rinse water. We used the radiator's drain cock and a slow trickle of water to finish up to clear.
All that neglect is behind us now. My friend still wants to add water pump lube and rust inhibitor. I can't argue anymore. Kira
