‘04 V8 with the entire coolant system replaced in the past 3-5 years with Motorcraft. While driving, the temp stays <205 and <200 on the freeway. I had to pick my sister up at the airport a week or so ago and the temp went up to 225 sitting in traffic. Once moving again the temp dropped...

Does it ever end?!?!? Now I have coolant coming out of the little hole on the drivers side of the thermostat housing. Is this a housing issue or an issue with the cap? Yes, everything has been replaced in the last 5 years with Motorcraft parts.

I thought I was going to get through the whole process without posting but…. I got the bad one out, but I can’t get the lower half into the bracket. What’s the trick? There is a sleeve that extends out of the bracket bolt hole and the alternator.

My 2004 V8 with 281k miles threw a P0022 (Over retarded) code yesterday. The car seemed to be running fine with no missing. After researching, the oil is clean and full. Looking at the connector, the green wire casing was split and I could see bare wire inside. I wrapped the green wire with...

I had to drive through what seemed to be the bowels of hell to meet my folks at a doctors appointment. Of course, I was nervous but confident of my recent repairs. I monitored the temperature while I was driving going from an ambient temp at my house of 80 or so to 116 going up a hill in...

I got everything back together after my overheating episode, new radiator, DCCV, and upper hose. Everything else is 3-4 years new. I bled the system using the manual's procedures twice but the temp keeps rising up into the mid 220s. I always monitor the temp via my OBD2 reader. My...

Just discovered my upper hose is leaking right at the 45 degree plastic part. I have a Motorcraft coming but was thinking if there might be an alternative...Jaguar? Or even something like this if the center portion was aluminum.

I started a thread about a recent overheating issue here but thought I would just combine the discussion since it is turning into one big job. 2004 V8 with 280k + miles. Two owner...my parents and then me. Very well maintained over it's life time. I've done all the normal repairs, cooling...

2004 V8. All the plastic parts have been replaced in the past 3-4 years. Yesterday, was in 100+ weather with the AC going. When the car is moving, temp is 205-210. When I stopped at a signal, the temp rose up to 225, on to the freeway back to 205-210. Today, mid-upper 80s running a few...

Let me start out by saying that my 2004 LS V8 with 280K miles runs great. I’ve done a lot to it over the past several years (including a rebuilt trans, suspension, cooling system with Motorcraft, etc.) and hope to get at least another 100k or more out of it. I know I have at least one oil leak...

My 04 V8 driver’s door keypad seems to have died. The 9/0 led went out a while back and now I am not able to open the door, lock the door, or have any of the number pads light up. Before I buy a new one or pull one from a salvage lot and tear the existing pad out, is there a way to test to...

This may be a complete knucklehead question but...does one remove the red piece before installation? Or is that part of the seal? I just want to confirm. I do have the 303-646 installer tool so that should make it much easier.

I began getting a periodic P0401 EGR Insufficient Flow code in my 2004 LS V8. I pulled the EGR valve and cleaned the insides with carb cleaner and reinstalled. Fortunately I had an extra metal gasket. Of course I dropped one gasket and it slide under the intake manifold. I tried to retrieve...

It appears the online manual link is dead. Or is it just me? http://deneau.info/ls/

11pm Friday evening, August 19, I head out of our neighborhood heading to pick up my son after the high school dance and a guy backs his Bronco out of a drive way right into my right bumper and fender. Not only does he destroy my LSE bumper and fender, the impact breaks the tie rod off of the...

Has anyone thought about or tried installing an oil cooler on the LS? I don't mean the V8 stock oil cooler that has coolant flowing to the where the filter attaches. I mean a separate air to oil cooler like the Mishimoto. I came across a couple of videos that show a significant reduction in...

My 2004 V8 has 269,000 miles on it and is running great after a rebuilt transmission and a number of various repairs and upgrades, e.g. cooling system, suspension, etc. I need to do the rear UCA's but will start a separate thread for that. I have a steady oil leak that is coming from the...

I need to get some new pads for my brakes. I currently have the Power Stop Z17 evolution ceramic. Any recommendations?

My '04 V8 with 270K miles has an oil leak coming from either the front seal behind the harmonic balance and/or the front cover gaskets. I include the front seal because I replaced that 3-4 years ago with the harmonic balancer and I may not have gotten it in 100% correctly. I am thinking of...

First, Happy 4th of July weekend! Second, '04 V8 with 267,000 miles. I've got 1500 miles on my refixed transmission and the vehicle is running great, except for... Third, car throws a P0420 code (catalyst below threshold Bank 1) every month or two. I also got a P0193 (High fuel pressure) a...
