Coolant leak HELP
Whats going on fellas, Im in need of help, my 99 Navigator(4x4 5.4)has been having a significant coolant leak. Right away I thought it was the water pump and having 100k miles suggested I should replace it as well with the radiator. Well to my surprise as I took off the old pump it was completly dry in the front but had a pool of coolant directly behind it on the block itself. Ok so I figured it was the seal that went bad. I installed the new one and at first no leaks until about 3hrs later and only drove it around my street for a bit and resulted with a pool of coolant under the truck, doesnt drip in the front but in the middle by the transmission area-guess it funnels and drips there. If someone has a clue please lmk also if someone could provide with the schematics of the cooloant system for my truck that would be greatn Thanks in advance!!!
