Ford 3.5 Water Pump Weep Hole
Ford 3.5 Water Pump Weep Hole. I see coolant on the bottom of the oil pan and engine oil. Compatible with oe number aa5z8501c, at4z8501ca.

A recent support request was sent in for this 2010 ford edge with a 3.5l v6 engine dohc with one vct actuator and sensor per bank: Without this hole, the oil would be forced past the water pump seal and get into the engine coolant. Compatible with oe number aa5z8501c, at4z8501ca.
Ford 3.5 Internal Water Pump Failure.
This is the reason why some of them even mistake it as a design flaw and they end up putting a screw. Checked the oil and the crankcase was full of coolant. Couldn't have built that into the original design or anything.
The Water Pump Was Leaking Through The Weep Hole Passage In The Block.
Water pump calls for 9.5 hours to r&r and factory pump is around $200.00 with all the seals and gaskets. Water pump inside engine mixing coolant and oil the ford explorer 2011 models saw instances where the water pump failed. This is a 2008 originally, coolant was pouring out the one side.
My 08 3.5 Edge Has 235,000 Miles On It And Just Put The First Water Pump In It.
The minor one is in the engine valley and can be seen with some effort and a strong light, towards the bottom left of the intake manifold. This ford edge has antifreeze coolant staining the a/c compressor & i believe it is seeping out of a small round plug which i thought was a tiny freeze plug however reading another post i believe it is the water pump weep hole? I've got a shop customer who's tech replaced a water pump and timing setup on a 3.5 eb and now oil is flat out pouring out the weep hole.
The Weep Hole Is Intended To Allow Extra Lubricant From The Pump Bearings To Drip Out Of The Water Pump Housing.
Now it's oil out the other side. The hole also allows coolant to escape the pump housing instead of being forced past the oil seals to contaminate the bearings. There are two weep holes.
Is That The Pull The Heads Water Pump Version?
Pressure tested system, no leaks found. Without this hole, the oil would be forced past the water pump seal and get into the engine coolant. The major one, where the big leak tends to happen is above the alternator/compressor, so to the side of the block.
