Dorman 615-188 Engine Intake Manifold for Select Ford Models

I am the original owner of a 2001 Expedition with 175,000 miles on it. I have performed 98% of all work done to this car. I replaced the manifold because of a coolant leak onto the engine from the passenger side coolant crossover section. Once it was off and upside down I could see a bulge in the plastic between the crossover and manifold. It leaked into cylinder 1 coil/sparkplug hole and shorted it out and into cylinder #1 intake valve. The sparkplug from that cylinder was burnt a brown color. I assume that was from the antifreeze leaking into and burning in that cylinder. I pulled codes for cylinder 1 misfire and both banks running lean. I installed the manifold in 13 hours total over 3 evenings after work. 4 of those hours were disassembling the throttle body and submerging it in lacquer thinner to clean all of the carbon from the ports and reassembling it. 2 hours were cleaning the fuel rail and injectors of residue. I wanted it as good as I could get it. You can do the job in 7 hours if you just want to get done. The manifold itself is nice quality. The coils, fuel rail and some other brackets use self tapping bolts that tap into the plastic manifold. The original uses brass sleeves to hold the bolts. They feel very solid so I don't think this will be a problem. That is the only negative I could find. The gaskets are included and permanently attached saving money and making it considerably easier to install. It comes with a new thermostat and seal. It comes with a new coolant crossover installed. Normally all of these things are bought individually. I have had it on for about a hundred miles. It seems to have more power than new. The lower plenum is smaller then the original and does not have a divider in the middle. I am guessing this allows for more direct airflow. It also appears the cylinder ports are arched at a better curve for airflow. I know it was 12 years and 175,00 miles ago but I think it runs better than new. I am extremely satisfied with the results. The price can't be beat. I rely heavily on this car for long distance trips. So far this is a fantastic improvement and purchase. If anything changes I will post it here. 1/10/2014 It has now been 600 miles since install. I could not be happier so far. I had codes for cyl. 1 misfire and left bank running lean and right bank running lean. It cured all of them. I did replace the spark plugs and cyl. 1 coil because it had antifreeze shorting it out. 04/26/2014 6000 miles now and no problems

Good

Tried everything first without success. Spoke with a Ford tech and was told the last thing to do is replace the intake. Difficult to do on an 02 F150 as the motor is half buried into the firewall with very limited room to work. It solved the coolant pouring out of the right rear top of the engine. Recommend to replace your spark plugs when doing it. You won't get a better opportunity.

Truck blew up after installation... probably my error . Good luck

I have a 2000 ford excursion with a real bad intake manifold leak, I bought this a few months back and recently installed it due to my truck losing 1+ gallons of coolant/water every time I drove it, also it would slowly leak coolant if it sat. A common problem in 5.4 triton engines, both gaskets on my crossover tube were broken as well as the plastic around the gaskets. I chose this intake since the gaskets came with it, and it was cheaper. To figure out how to install I used the service manual for my truck and several YouTube videos. Installation is not for the faint of heart. Took me two days to install, but of course working on an older vehicle things tend to break and repairs are almost never as straightforward as it seems. I didn’t have any problems with installing it, the bolts that came with it worked perfectly. Lucky for me they came with those bolts because I broke a few when taking off the old manifold. So far my truck is not leaking and is running great. Even the ac seems to be cooler. I might update later after putting more miles in to see how this doorman intake holds up.
