Water leak on top of engine of a 1995 town car

My rodeo had a leak under the air intake plentium theres a medal pipe runs threw there the O rings was dried out and started leaking

It is most likely the water pump, the air flow under the engine causes the coolant to go back under the truck. Fell under the front of the water pump for moisture or a slimy liquid.

95 Lincoln town car coolant leak under intake SOLUTION EASY

Ok this is a 4" piece of hose leaking on a tube that runs under the intake manifold and fastens to the rear of the engine with 2 small bolts that are very hard to get to. The heater core hooks up to this tube with a 5/8 hose that's 3/4 on the other end going into the heatrer core.
Solution:
remove alternator
see clamp on hose?
remove it.
If you can't remove it, clamp vice grips on it and take a steak knife and cut through the hose towards the rear of the engine. Now with large screw driver pry the hose and clamp off the nub on the rear of the water pump housing. You may have to move the tube and remaining hose out of the way first. Just stick your hands in there and force it out of the way. Now you have a clean nub to hook a 5/8 bypass hose to. Here's where you get it. Go back to the heater core and and remove the hose that connects to this tube that runs under the intake. Just cut it where it hooks to the tube and remove it carefully from the heater core because this is now your needed bypass hose. Now with a couple feet of 3/4 hose and a coupler you have all you need to reroute this water outlet around the engine to the heater core. Take your hose you cut from the other end of the tube and removed from the heater core and and fasten it to the nub on water pump housing use new screw type stainless Steel clamps. You have to take this one apart to put it on. Stick a 3/4 coupler into the other end and route a long section of 3/4 hose under alternator to the heater core using SS clamps where needed. job done... Just leave the old tube where it is under the intake manifold......Thank you Very Much

make sure the engine is fully warmed up (check the temp gauge and feel the top hose from the radiator to the engine) that hose should be HOT and it you should NOT be able to calopse it-it should feel hard. If you do not have a leak under these conditions, you probably just have an overfull surge tank and it 'puked' out some fluid. If you top radiator hose is NOT hard after the engine is fully warmed up, you have something wrong-it could be as simple as a radiator cap that is not sealing properly, or a leaky hose, an intake manifold leak, or an internal leak in the engine (don't rule out a leaking radiator, it has end tanks that can and do leak).

Yes its likely most water pumps have a small hole on the under side of them called a weep hole. Its there to let you know that the seal is starting to leak and the pump needs to be replaced before it completely fails say on the highway and dose a lot of damage to the engine If its coming out the bottom center of the pump shaft and just driping a little then its time to replace the pump you should be able to feel the hole with your finger

The only way to fix it, is to find the leak, and repair it. Hoses? the intake manifolds are famous for cracking behind the alternator if it has a plastic intake manifold. But you are the one that has the car, so You have to find out where the leak is.

Check for leak at the coolant tube that runs under the intake, possible bad o-ring, the intake will need to come of for inspection and repairs.

There is a heater core bypass pipe that runs from the block (under the manifold) to the bacl of theengine where you will see a flat rectangular "sheet metal" thing with a pipe coming out of it. The a rubber hose connects. You need to pull the top air plenums and intake to get to it. The p[ipe flange bolts to the block with silicone rtv as a sealant.

really this could be one of several issues, does the vehicle run Hot, are you having to fill the reservoir with water or coolant, there is a hose that runs from the cap (overflow hose) to the reservoir, in addition to the upper and lower hoses, finally the water pump. the water pump is equipped with weep holes, which allow fluid to weep out when the pump is bad. finally the thermostat, hopefully one of these can solve your issue, good luck!

I know this darn hose, u have to pull the intake to replace it, we used the factory hose but you can use any type of water/coolant rated hose in that size. The intake is not that hard to remove, 30 minutes or so if i remember right from Ford dealer days.
