Use of a higher than recommended pressure in the cooling system can cause serious problems, if the radiator itself is not designed to operate at higher than usual pressure. 16 psi is commonly the highest supplied cap by manufacturers. I have seen radiator structures visibly contract upon release...

TCM being "Transmission Control Module"? This is a new addition, then? Transmission control has always been handled by the PCM in the past (2004+). Regardless, though, control is not being "controlled".

Your concern is evident, and significant. Your Dealer apparently does not understand thoroughly the operating principles of these new transmissions. IMO, if this problem were a common one, news of it would have Ford jumping up and down; thus it is probably unusual. My guess would be the...

Pack rats are even worse. Had battery cables chewed through! Had a fire start where a plug cable was chewed through leaving about a half-inch gap: arc caught insulation on fire, which caught coil, then plastic intake manifold. Fortunately, I caught it in time driving to town, bought a plug wire...

Visual test: look closely at all the fuse links; some have 4 or more, some only 2. Discoloration indicating excessive current suggests replacement.

Possibly the best I've used for batteries is the super-flexible cable made for arc welding. Oil-resistant insulation, many fine strands, very easily in stalled, but best clamped well in place. I have big, heavy solid copper lugs for bolt terminal ends. Note the large metal area around the...

Has independent suspension, Ford 8.8" gear center section solidly mounted, which is specially-made for insertion of CV half-shaft axles. What part of the mess are you proposing to change? If you mean which GEAR RATIOS can be used, answer is several.

Evap. Canister Control Circuit Solenoid. Opens to vent canister of fuel fumes into engine. Check for: broken/cracked vacuum hose leading to solenoid, solenoid coil resistance, resistance to ground. If all good, solenoid plunger may be stuck. Buy new solenoid, not a big cost item. Or ignore CEL...

Battery cables were heavier gauge back when 6-volt batteries were the norm. High-grade cars (like my Dad's Lincoln) had fat cables, maybe 1-0 gauge. Almost unbendable. Today, with starting currents lower (higher operating voltage, 12V), the cables are chintzier by far. I've picked up jumper...

Under the hood, RH side (passenger side) below the hood hinge supports, you can see the 3 big connectors hooked to the computer (PCM) which is mounted INSIDE the vehicle on the firewall. Removal, or access, requires removal of the plastic RH side foot "kick-plate" in the vehicle. Two bolts...

A poor connection cannot drain a battery. However, big accumulations of crud over the top surface of the battery (which contain electrically-conductive acid) have been known to slowly drain a battery, though very quietly and not noticeably. 5 years is a decent lifetime for low-quality batteries...

Did you thoroughly CLEAN both the battery posts and the insides of the cable clamps, where they surround the post? All surfaces should be clean and shiny, the blackened crap and corrosion thoroughly removed, by scraping if necessary. Then, apply good grease, like vaseline, liberally to the posts...

From the factory, they came with one-piece control arms on left (driver) side, two-piece on right (passenger side). The two-piece had a bolt-adjustable feature to "fine-tune" caster setting, to assure equal caster on both sides. Some replacements in the aftermarket came without the adjustable...

The gears you call "spider" gears are in reality axle gears. The spider gears are the smaller two. Unless I'm seeing the images incorrectly, the axle gear on the left side appears half gone! There must have been a lot of metal shavings in the oil as well as sitting on the bottom of the center...

All things in the automotive world seem to have become more complex! But, pistons in cylinders with valves controlling fuel/exhaust flow are pretty much the same. Several things you must know which I do not: Some interim period Ford drove the old-fashioned speedometer head, analog, using a...

The ages old system used two speedometer gears, one on the transmission output shaft, turning at driveshaft (pinion gear) speed, called the "Drive Gear", the other on the cable leading up to the speedometer head, this gear called "driven gear". Invariably, the drive gear had less teeth than...

Look at the basics: Crank, no start........IGNITION: Is there spark? FUEL: Check for spurt of fuel at Fuel Rail Schrader Valve after cranking. If dry, no fuel to injectors. Then figure out IF pump is running. If it is not, check Inertial Safety Switch, reset if tripped. If not tripped, check...

I believe Ford used a returnless concept, to which you refer, for several years, finally going to the speed-controlled pump to maintain constant pressure at the engine. In '99 version, the pump put out maximum volume at all times, dumping the excess back into the tank, constant pressure being...

This being true, have you given much thought to the "returnless" fuel system in which the pump SPEED is continuously being varied as needed to maintain volume sufficient to maintain expected pressure? At first, I thought this was nonsensical. Dead pump every few months, but know what? 170,000...

I can post that for you, but will not get to it until later today. EDIT: Found sooner than expected: BUT, this diagram is for 5R55S not "E" transmission; there may be some differences, unfortunately. Suggest getting the ATSG booklet on 5R55E. That manual is listed here...

You thought it wasn't going in to Overdrive, but likely it actually was........the last "shift" seen on the tachometer is the TCC locking up. 5th. gear happens first, TCC last, around 50 mph with minimal throttle demand. The TCC solenoid (or any of them) can be tested for electrical continuity...

Somewhere around 2002-2004, the IAC was eliminated altogether as they went to drive by wire. My '04 has no IAC.

There is NO 4X4 Module on my 2004 Ex. Only two individual relays mounted on the right fender inner apron, near the firewall. The Module has been incorporated into the PCM. When this change was incorporated, I can't say.

Try calling a Ford Parts man. With luck, he will help you without touting his facility.

Jak csye idzje Can say it, but not spell it!

With this type of u-joint caps: The bolts are usually 1/4-28 or 1/4-20, if Dana parts are in use. This type, also Dana, uses 5/16-24 usually, though I've seen 5/16-18. Either are OK, so long as the nuts are correct thread size. Sorry I can't tell you more.

Maybe, but only a highly experienced builder can answer positively. One of the most critical specs in auto transmissions is the spacing of internal assemblies with respect to each other. This is accomplished by a series of thrust bearings and spacers, to ensure line-up of the holes in shafts...

How does one swap a bell housing on a transmission having an integral bell housing of the wrong fit?

If you have not yet done so, drive up through Superior through Miami and Globe, amazingly scenic; pass the Ox Hide Mine Road, Blue Bird Mine Rd., looking out almost to eternity. I worked with a guy at Sears who was born in Superior; he retired there. Same vicinity Boyce Thompson Arboretum, where...

Vapor Lock occurs when the fuel gets hot enough to BOIL, thereby creating liquidless areas of gas. At the pressures used with efi systems, vapor lock is a thing of the past. If design parameters are not messed-with. Heat wrap would help only if the temperature of the area surrounding the fuel...

Please describe how this journey takes place: pieces get ejected out of exhaust port, sucked back into another? New concept, to me.....

Most are saying NON-INTEFERENCE> I ain't sure............... "Fortunately, the 4.0L SOHC is not an interference engine so a timing chain failure won’t bend the valves."...

A torque converter can only drain out 1/2 of it's contents if it's standing still, all through the center. The rest sits in the bottom half below the center hole. If spinning, none can drain back; the running engine pumps the fresh converter full of oil, which fills it from the outside in.

Many, if not most (all Fords I've seen were) front crank vibration dampers have two steel rings bonded together by a rubber interface. With extreme age, they do loosen and shift. Bad news. Aftermarket dampers may do away with the bond, I don't know for sure.

The SOHC is said to be NON-INTERFERENCE. As such, the timing of valve motion, broken or skipped chain cannot cause piston/valve interference, IF it's non-interference design. The broken off land on the piston is likely a fluke in manufacturing, possibly heat treating.

This is true. But the VOLUME generated by the valves' movement amounts to only a few cubic inches, out of many needed for correct compression ratio, say, 50cc, or about 3 cubic inches, it would seem the combustion chamber volume could be built around the valves' intrusion into the cylinder...

AWD has no switches, feeds power to front wheels via a viscous clutch, always engaged. FOUR-WHEEL DRIVE having switches has NO VISCOUS CLUTCH, but rather an electronic clutch, may be ON or OFF. With the latter 4X4 AUTO engages the clutch when wheel slippage is detected. 4X4 HIGH keeps clutch...

Anyone willing to take a crack at this? I've been trying to imagine why, in this age of OHC engines, anyone would offer an interference engine? Obviously, both types exist. I picture the valves, 2 of them by example, "using" up a certain amount of combustion chamber volume, into which no piston...

Yes.
