Question about 2000 Ford Expedition

Intake manifold leak fixed

After replacing the intake manifold on our Ford Expedition, it won't start. It was running before we replaced this (replaced due to leak of antifreeze). Now, it's turning over, but will not start. Checked all wires and cables. What's wrong?

An engine needs three things to run air, fuel, spark. So check to make sure air supply is adequate. Check fuel supply. Check to see that all air has been bled from the injector rails. Check wiring again . Make sure ground strap is reattached from firewall to engine. Pull off a plug wire and check for spark. If distributor was removed make sure it was reinstalled correctly and it is not 180 degrees off. Recheck all plug together connectors. Hope this helps.

SOURCE: I need to drain the

Not 100% sure but if you look up under exhaust manifold area, on block,is usually a common place. Simple hex head plug into block on most. Are you sure just pulling lower rad hose, and thermostat housing off won't get you where you need to be?

SOURCE: intake manifold leaking coolant at expansion tube nipple

It is pressed in. I usually just take the nipple out and run a threader into the hole and place a piece of threaded copper pipe into the newly tapped hole. The factory uses a thin steel tube and they rust out if the cooling system is not properly maintained.

SOURCE: coolant in # 1 cylnder\clean intake port of intake manifold

Check the lower intake gasket again the new gaskets that are being use made out of plastic with rubber port seals sometimes don't seal right I still used gasket sealer with the new plastic gasket even if it has rubber seals. MY 4.2 v6 had that problem but I went ahead and replaced the head gaskets also just to cover all the bases. And my F-150 has 210,000 miles on it. Make sure you tight the bolts I know it probably calls for something like 8 ft lbs which to me is not tight enough. Double it.

SOURCE: 98 Expedition coolant leak top back of engin

Sorry im late with this,i couldnt seem to log on....The answer to your question is YES,there is a steel line under the intake with a short piece of rubber line attached to it and you can just about see it from the front of the intake with a light,it can leak and cause coolant to run off the back of the engine,The intake gasket set alone is about $40.00 and i dont know about the rubber line,i have seen it physically but havent changed one yet.Note the date of manufactor just incase,i bought an intake set for a 99 and the engine design was changed half way through...its not too hard to pull off the intake and re-install,you will need a 7mm socket for the coil packs,8mm socket for the fuel rail bolts and lower intake bolts and power steering bracket bolts and throttle bracket bolts,10mm socket for the intake bolts and alternator bolts and egr valve,and a large cresant wrench for the exhaust tube thats connected to the egr valve,flat screw driver for the air cleaner...and plenty of extensions with a swivel to be able to get to the back bolts of the intake....just incase you do it yourself this info could make it easier to gather tools.Its about a 3 1\2 to 4 hour job start to finish for the first time doing it,includes cleaning everything..Good luck

Tip

Intake Manifold gasket replacement and/or leaking= Ford


Intake Manifold gasket~

Replacing intake manifold gasket:
Replacing the intake manifold gasket, I used the tube kind, it's a make it youself for about $6 (it's blue and the consistancy of toothpaste) follow directions carefully! You can get a tube at Autozone or any car parts store. Has been working great. Just ask the cashier for the make it yourself kind of intake manifold gasket. Sorry, I don't remember the name of it, it's been that long...lol...

As for the Intake Manifold leaking coolant....It could, but shouldn't. One of the largest problems I've seen for coolant to leak out the Intake Manifold has been due to pressure in the system somewhere... Check the classic area:
Water pump- look for either water seapage and/or coolant. You'll know if it is because you will see real water either coming out of the water pump leak hole or under the thermostat. Most of the time coolant will pool where your heater hose runs in the intake manifold.

Mentioning heater hose. Check for leaks, holes, and/or cracked heater hoses. In-addition to the water pump, heater hoses...Check the transmission system, exhaust system, fuel system, radiator system, A/C system, secondary fan (located above the water pump housing), and thermostat.Also, check all electrical connections....Hummm....This is almost the entire workings of the vehicle.

NOTE: "It seems to be an infinity kinda thing... Once one thing starts to fail and is ignored, you are bound to be fixing a chain of event failures. Therefore, Do not ignore even the smallest problem or you'll be bound for life in repairs...."

My 1998 expedition with the 5.4 triton runs rough at idle but clears up when driveing down road I know I have a manifold leak and the previous owner said it was a coil pack, however after I had advanced...


If you have a manifold leak that will cause a MASSIVE vacuum leak and make it run rough at idle only. Look at your short term fuel trims with a scanner, if they are way negative you have a vacuum leak. Fix the intake manifold leak and that will fix your problem.
