Does the concentrated coolant like Rotella ELC need to be diluted? I keep seeing people say 50/50 but the tech specs on the coolant says not to dilute with other coolant or water more than 15%.
I’m changing a bad water pump, so I’m going ahead and flushing out the coolant system and replacing coolant filter on it, just not sure about the whole concentrate or 50/50 thing.
