Ford - Explorer :: 1994 - Running Hot Towards The High End Of Normal Area
Jun 17, 2013
Its a first Generation I have had about a year, had some of the typical issues with a vehicle this old---bad connection with a relay under hood, cracked fan blade, IAC, nothing I could not find.
Temp (issue is getting worse) runs up to high end of "Normal" yet I note radiator does not seem overly hot. (to the touch).
Antifreeze tests very good and is full---no signs of leaks or liquid in the oil.
I am hoping thermostat or radiator===vehicle has been well maintained and does not show rust in the coolant, and no signs of leakage around the pump or anywhere else---coolant level does not drop.
I am planning on removing the thermostat and seeing if same issue with it removed====it should rule that out or not----
It is not boiling over but just running towards the high end of the normal area.

1994 f150 with 4.9L I6; 180k mi.
Parked vehicle last night after using it uneventfully for work the day before. Upon leaving the house at 11:30 AM, I noticed that I'd picked up a new mechanical noise. Nothing major; actually wasn't sure I heard anything at all.
As I drove to the store, I noticed it was idling slightly unsteady...much less so than a missing cylinder. I resolved to check the high-tension connectors when I got home for security. I glanced down at the gauges to check and see if my oil pressure was good; I then noticed coolant temp reading "high normal."
When I got out, I noticed a small pool of coolant forming. I looked at where the puddle was forming...the radiator hose had come off! (Actually separate from the radiator connector, as one might do if draining fluid without using the petcock.) I popped the hood: no unusual smells. Nothing seemed abnormally hot. Placing a finger against the head was uncomfortable, but not painful. Spit expectorated upon the head did not sizzle.
I then called my wife, explaining the situation, and walked back home 2 miles. We then took the spare car, bought antifreeze, and added it about an hour post-shutdown. Where the car was parked seemed wetter than the light drizzle allowed; daubing a finger in it and tasting gave a slight sweet taste.
I tend to check my fluid every so often (not every day, though) and coolant was verified as "full" as recently as 100 miles ago. (I don't make a habit of crawling underneath, though, so I couldn't tell you if hose had been slowly backing off or not.)
As to cause: is it plausible that this could happen without foul play? There have been a few vandalism incidents in the neighborhood; it's also possible that I [peeved] off a neighbor recently. I'm not about to go any further than fixing, though, unless there's really no other plausible explanation.
As to the mechanical questions: How much damage was done? Did I "catch it" in time? What is suggested as far as repairs/maintenance? (I was planning on doing a compression test, and keeping a close eye on fluid levels over the next 1,000 miles or so.) Engine sounds completely normal.

I have a 98 ford explorer just changed the alternator and now its running rough also it sounds louder than normal from the muffler. I am clueless, what the problem can be?

Most of the time, my speedometer needle is steady and in the right spot. But once in a while, it will indicate several mph too high, along with some slight fluctuation. The tach and the GPS speed remain steady. What would cause this? I would think that a worn component would cause it to indicate low or bounce around all the time. Also, where would I get a speedo drive gear with a different number of teeth, since I have 31-in. tires? I look on parts store websites and don't see any drive gears. 1994 Explorer..

For reasons I can't figure, the Temp gauge on the wife's Explorer is shooting from normal to high in just seconds. Then, it drops back to normal. When I looked at it this afternoon, I noted 2 things.
1) There was no sign of a coolant leak or overheating.
2) There wasn't ANY coolant in the tank!!!!!!!
The truck has evidently been running fine while this is going on.

2003 ford explorer 4.6L. This truck will start and run rough high temp low oil light come on and temp gauge is pegged hot. Oil gauge is fine though, checked oil its fine.
I checked coolant reservoir its ok.
If I shut truck off and restart it will run ok and rev like normal and then all of a sudden go into limp mode and will misfire etc...
What sensor seems to be the main culprit?cht sensor???

Srange noises of my 1994 AWD. When driving, if I take off fast, it makes a lot of pop noise, but if I take off slowly, then It's Ok. Or when I make a quick acceleration after slowing down then it make noise, but if I take it fairly slow then it's OK. The frequency is getting worse. My front axles are in good condition (30K miles on a rebuilt pair). I have unplugged the AWD controller box, it didn't do any difference. All gear shipped OK. So what is that noise in that condition? My 94 AWD is about 110k miles, good shocks.

I have a 94 celica gt and at random times the power is much greater than normal. it seams to happen most when the engine is not fully warmed up or if I'm driving all day and it starts to cool down for the day. normally my 0 to 60 time is around 8 to 10 seconds and when this happens the time drops to around 6 seconds. I also have a 93 Toyota pick up that does the same thing and another 94 celica that doesn't do it.

I have a 1998 Explorer XLT V6 (4.0 SOHC) with an AC problem. The AC compressor will not turn on via normal means - turn to AC or AC Max, rotate temp to left. It hasn't been a problem as I never use the AC, but I'm fixing a few of the minor inconveniences (dash lamps, re-solder radio) and figured, why not look at the AC too.
A while back my mechanic said he used the Explorer to test his AC equipment and made sure the Freon was good. He said everything was working. I am assuming he was able to control the AC system from his tools under the hood. This tells me the system is good and the problem is related to the temperature control or a switch somewhere.

My 1994 Explorer is stuck in 4 low. None of the lights are on in the dash or at the switch. I got the switch out & with a test light running I have weak power at the top left terminal better power at the 2nd, 3rd &4th on the right. No power on the opposite terminals. Is my switch bad or do I have a different problem. Also how do you remove the switch from the dash vent ?

So I was doing my coolant flush yesterday and turned on the heat, both front and rear, to move any old coolant out of piping and cores. I notice that the rear was not blowing as "warm" as the front.
I did notice that the compressor was clicking on and off the whole time. A/c pipes coming off of accumulator were freezing up/getting cold/frosty.
Is it normal for the compressor to do this when the heat is on?

I have a 1994 Dodge RAM 1500, v8, 5.2 liter truck. A few months ago, I noticed that when it's at normal temperature, it would not crank unless I floored the accelerator. Once it cranked, it was hard to keep it idling at a constant RPM. I have to rev it up a lot to finally get it to idle by itself or to put it in Drive to move. Once it's moving, everything seems pretty good. If I stop and change gears (Park, for example), it will stall. I have also noticed this happening if I'm in Park, then turn on the air conditioning putting a load on the engine, it will stall.
When the engine is cold (sitting for several hours), it cranks fine and runs fine.
I have replaced the idle air control (IAC) valve, the throttle position sensor, the MAP sensor, the Crank sensor between the motor and the transmission (what a pain to replace), the O2 sensor upstream of the catalytic converter, and the computer (with a used one from a salvage yard. And, I had a mechanic check out the distributor cap and it's internals and do whatever he did.
I did read somewhere that the coolant temperature sensor may be an issue?

Working on a friend's Explorer. The car idles fine, but once he starts driving and gets to about 35 mph, second or third gear, the car loses power and eventually dies. MAF sensor replaced, no change.

I'm replacing the compressor and accumulator on my Explorer. I'm having the shop evacuate the system, but they want to fill it with R134, so I'd rather use the cans if I can find out how many ounces it needs. I'm seeing conflicting information on the refrigerant capacity for the 94. Is there an authoritative source, like the factory service manual?

Bought a used 94 explorer xlt. It came with brand new Wrangler tires. The day we bought it we were driving home and it started shaking and wobbling at about 95kms and but seemed to improve after 115. So I took it to the tire shop next day and had all 4 tires rebalanced. The shop told me that all were out to lunch. The worst was 2 ounces out. Ok cool. Was certain that was the problem. Paid the guy and took off. Got on the highway and same damn thing. The steering seems very tight. No bangs. No knocks. Just the bloody shaking. Oh and also the abs light comes on just as it starts to shake. I don't wanna head to a garage to find out some nightmare when I get there. Want some heads up on it first.

Twice in the last year my 1999 Ranger (@138,000 miles) has started running very loudly: I checked dash and see oil pressure gauge says no oil pressure. First time this happened, I pulled over, had it towed. At garage they start it up: gauge normal, they check oil says its OK. I take it to the dealership, they replace sending unit, but can't explain why it was running loudly. Today same thing happens: I checked oil pressure gauge, it's OK. After an hour, starts running loudly, gauge in red. Park car for 15 - 20 minutes, start it up: all is well: gauge OK, running quietly. This is amy 'spare' car, so it only gets driven 1 -2 times per month, short distances.

I've replaced the fuel pump and filter, plugs and coolant temp sensor. It starts after I spray starter fluid in after a few times and cycle the key on to prime the line but is still hard to start. It runs fine and it seems that as long as the engine is warm or (guessing) fuel is still pressurized in the line it starts fine.

The last couple of times hauling wood with a trailer, the 1994 Explorer seemed to seriously lack power. Then I noticed there was an awful grinding noise coming from the rear. My guess is that the wheel bearings are shot creating an enormous amount of extra drag, especially with the added load of the trailer. Or what else could it be? How much should I expect to pay to have bearings replaced?

We have a 94 ford explorer and every now and again it has issues on the start up. It will sound like it will want to crank over but just won't. If we wait 20 mins it will start up no problem. We have changed the fuel pump, fuel filter, ignition coil, and fuel pump relay but it still has this problem. Also occasionally the a/c blower wont turn on. Tonight it happened again and I pulled the fuel pump relay out and it was really hot, after it cooled down and was put back in the car started. I am beginning to think it maybe an overheating issue that is affecting the relays but am not sure. I was also wondering about changing out the relay box...

1994 Explorer V6 100,000 miles, it is getting fuel and spark. After driving for a short/long period the engine will turn over but won't start. If you floor the gas pedal it will fire up, with a small puff of black smoke out the exhaust. Fuel pressure regulator came first to mind, and has been replaced. Problem was cured for a few days, then it started again.
Next Idle Air Control solenoid. Replaced, with same results. Replaced EGR position sensor. This worked for a few weeks. Then starting issue came back. Then I was told to replace fuel pump relay. This was the last part replaced. It had been running great. Started warm without any issues for a week. But now I have a check engine light and hot start problem again.
If the gas is floored the truck will fire. If gas is not floored the engine keeps turning and turning. I am sure it is not a fuel pump problem, as there gas fumes and the tailpipe is black. Could it be Mass AIR FLOW ?

My daughter has a 94 XLT with 4 liter OHV. This the first time I have noticed a vehicle to have both an oil light and a pressure gauge. Periodically the check oil light will come on, but the gauge shows very good pressure. The oil level is full. I'm not sure what to make of this. I know the engine was replaced with a rebuild but no idea how many miles are on it now. Oil looks fairly clean tho it is due for an oil change I think.
