94 f150,302. my pump is still leaking after doin the job twice. its a new pump, the first time i used the red silicone between pump and plate,both sides of gasket,and the housing on the block. leaked. then did it again with high tack gasket cement and still leaks. i cleaned all metal both times with brake clean before installing. same with thermostat housing,small leak. ive done 100s of pumps over the years,no problems, so please no rude remarks on mechanical ability. what could it be? it leaks up front of the motor above the crossmember where ya cant actually see the leak,its not a freeze plug. bolts are torqued. any ideas ? thanks
Die and tap the bolts and holes you might be getting false torque measurements. take a straight edge to your new pump, It could be fuggered right out of the box.
problematic point. lookup on to a search engine. that will can assist!
Pay an automotive repair shop to do it. Then it is their problem. Even the best technicians need help once in a while. Yes it costs 3x as much, but no more headache for you.
never rule out a freeze plug. it could also be a cracked block. it could be in your interest to pressurize the system and trace the leak back to the source. the pump could be fine.
It's not the pump that's leaking. The water ports to the pump pass through the aluminum timing cover, over time the aluminum corrodes and leaks between the block and the timing cover. You need to remove the whole works and replace the timing cover, may as well do the timing chain since you're in there.
