The two Radiator fans are always running even at start up on a cold day. I have not had time to investigate as yet but I am assuming it is the temperature sensor located near the thermostat or a relay. No CEL on. What it likely is and how to approach the trouble shooting?
View 10 Replies96 intrepid, 3.5 motor. Runs fine, no loss of power or odd behavior but will just die. Like flipping a switch. Refuses to start. I checked fuel pressure and it's good. No codes. Does this motor have a MAF? Sure can't find one. It has the odd split intake plenum. 1 air box but 2 separate inlet ducts to each side of motor. The motor is not transverse. It has 2 throttle bodies on the firewall side of motor with a shaft that runs between them. So eventually it starts. Idles fine. I watch it idle. And click, it shuts off.
View 2 RepliesAfter about 10-15 minutes, following a cold start, this 2007 BMW X3 3.0 six does the following:
1) automatic cabin fan behaves erratically, jumping back and forth between low and high speeds;
2) cabin air does not heat;
3) electric radiator fans run on high;
4) coolant temp rises to normal, but then will suddenly jump up to full hot.
At this point, driver of course pulls over and shuts off engine. The amazing part is this: the engine can be re-started IMMEDIATELY and all of the above problems vanish instantly. Radiator fans shut off, temp returns to normal, cabin fan works normally, and cabin heat comes on. I'm thinking sticking thermostat, but why does shutting off the car momentarily fix it? Change of water pressure when coolant pump stops running?
I have 2004 Dodge Intrepid 3.5L with 153K miles. For the past tow months I am getting oil in the radiator but NO antifreeze in the oil. Oil level gets low but the transmission fluid is fine. No coolant smoke, No Oil smoke, Have been draining coolant, Passed emission 3-months ago, Gas mileage is fine @ 23MPG. I have to add about quart a month (1000?-miles). I have been using Mobile-1 synthetic since bought the car at 108K. Currently 153K miles on the engine. Two years ago water pump and timing belt was replaced. If it is the head gasket then why oil is fine and no coolant in the oil. It is Not transmission Fluid either.
View 7 RepliesI backed out of the drive way with My 96 Dodge Intrepid yesterday and when I put it in drive I noticed the CEL came was on. Seemed like it came on with in a few seconds of driving forward. I was driving slow as that is what is called for in my neighborhood and all seemed ok. About 2 minutes later when I was going about 40 I noticed the Tach was at about 3k. I seems it will not shift into 3rd. I moved the shift lever several times and it did not seem to impact anything. I immediately drove home and used my other car to go to my appointment. It did seem to shift fine other than that.It never got to warm so I did not check the fluid but I did check it a few days earlier and it was ok. We had snow the previous day and I would have noticed any leaks on the drive way, which I did look for, and did not find any.
I know I need to get the CEL read. I need to drive about 10 miles to get somewhere to do that. Is there anything else I can check or try before hand? My guess is it is an electrical issue as it happened fast with out any warning. I don't have a lot of experience with transmissions but my guess is it is a solenoid not working. It may be fried or it is not getting a signal. Possibly VSS or something in the powertrain module or what every they call it in Chrysler world?
96 dodge intrepid, 3.5. Few yrs back kid flooded it at -10f. I changed wet plugs and it started. Ran ok for 10miN, idled fine .n than I drove it 10 miles and it would not idle. I was 150mi from home and kept going. Car ran so-so. Seemed sluggish at 60mph. Exhaust actually made black/soot stain on bumper. My mileage on hwy was about 1/2 normal. I pulled plugs when I got home and they were black. Took about 1 week of driving to eventually settle down. Never did find any reason for issue. Some said my o2 sensors were buggy. I never changed them and had car for 2 more yrs and it ran great. Why it would not idle?
View 4 RepliesI can usually find what Im looking for with a quick search but I have had no luck with this issue.
View 19 RepliesBackground: Check engine light indicated a problem with the throttle position sensor (unfortunately, don't have the exact code). The TPS on my model ('96 Dodge Intrepid 3.3L) is the non-adjustable type. There are three wires going to the TPS -- a power source, a signal wire, and a ground. The TPS acts as a potentiometer and depending on the throttle position, sends a voltage signal down the signal wire to the computer.
Here's my question/issue: After disconnecting the TPS, I tested the three wires with a multimeter. Power source (5V) and ground were fine. But I'm getting a voltage reading of about 4.35V on the signal wire. It's my understanding that with the TPS disconnected, I shouldn't be getting any voltage on that wire. Does that sound correct? If so, what would be causing me to get a voltage reading there? I'm assuming some type of problems with the wires, maybe an exposed wire on the signal wire somewhere?
Both my radiator fans run all the time, even if the engine is cold. Soon as I fire it up, even if it's 0 degrees, they are running. To be clear, as expected, the fans do not run if the car is off.
Based on these symptoms, what components could be the culprit?
Lately, I've noticed that when I start the car in the morning, the radiator fans come on at full blast, even though it's around 20 degrees F (not all the time, but most days). My temperature gauges all show (what I assume are) correct temps as it starts out cold, water first goes to 200 and stops, then oil slowly climbs and stops at 200 I believe.
They don't climb any faster or slower that I've seen, and usually by the time I get to work (around 20 minutes), the oil temp has probably climbed about 3/4 of the way to normal while the water is steady at 200.
Is this normal? I don't recall this happening, as I would've noticed as the fans are quite loud at full blast. I haven't had a chance to run a diagnostic scan yet, but the car hasn't warned me of anything either.
Here is the history of the car. 1997 Dodge Intrepid, 3.3L V6, close to 200k miles. Bought used 8 years ago.
Engine was replaced by previous owner due to front end accident at 90k (about, memory is fuzz on the full miles). Previous owner was a sales lady and had a repair log. Kept car running like a coo-coo clock since work paid for the maintenance. Her insurance paid for the repair then her work would not continue to pay for upkeep, due to accident. Since I bought the car, I kept in the same frame of mind of maintenance and upkeep.
- Oil is changed regularly and on time (no burning or loss, still filled to levels with synthetic high mileage oil) (Color - maple syrup amber, due to be changed in 500 or so miles)
- Water pump changed 3 months ago (no oil in the res. tank)
- Alt. changed in 2006 (30 - 35k miles ago)
- Ignition Coil and spark plug wires in 2006 (30 - 35k miles ago)
- Battery replaced in 2007 with a new one)
- Spark plugs last Feb. (about 10k miles ago - Look semi clean and are all gaped still to the manual specs) as well as the 2 belts on the engine.
(Timing chain same age as the replaced engine at 90k)
- All the instrument panel lights work, as well as head, turn signals, interior and tail.
Has for a long time (4 years or so), has an engine light on for an O2 sensor (Code 0134 and the meter I have).
The exhaust system had disconnected from the Catalytic Converter (engine side) last winter (9 months or so ago) due to weathering (clamps rusted off and pipes separated). Recently I repaired this 2 weeks ago (noting heavy black soot in the pipes and around the area on the underside). Once replaced had a cloud of soot when I floor the gas hard while driving.
Yesterday while driving after 10 mins from home while accelerating I noticed a loss of power (slowing down) instinct was to press the gas, did so, and slowed down even more. Car drifted to a stop, engine power was also gone (power steering was gone also). When this happened, there was No banging, or clunks, or loud sounds, or overtly ominous clouds of smoke. Engine turned off (while costing to a stop the engine acted as if out of gas - hence no power steering). Got a tow home.
The starter turns the engine over with no clatter, banging, or clunks. No backfires or "Coughing". Same sound as of before, but won't catch and run under own power. (Still acts like no gas, but has half a tank) (battery still has a full charge - spark plugs still spark - took one out of engine while still connected to spark plug cable grounded to engine for testing. No overtly heavy gas smell or residue on plug or during test).
My friend who assisted in the exhaust repair says that it is not the Catalytic Converter being clogged (I believe it is). His suggestion is a faulty sensor somewhere else, maybe cam/crank sensor, maybe MAP sensor, maybe ignition switch, bad EGR or even a bad ASD relay. Don't want to be buying parts to no end on this, need other input to narrow down a direction.
Last weekend, the car wouldn't start after sitting for a few hours. After about 20 minutes it finally started. It has started and ran fine up until today. Same thing, it was parked for a while and wouldn't start. Then it did start, ran horribly, then died when it was put into gear. Then it started and ran just fine, my friend moved the car, parked it and turned it off and of course it wouldn't start after that.
I've done a lot of work to this car myself, including entire tune up, fuel filter, cam AND crank sensors (notorious problems on these cars), ignition switch, oxygen sensors, several other things in the past year or so. My only hunch is that it might be the auto shut down relay, but I'm not with the car so I can't test that. We had fuel pressure at the test port the first time this happened, so I wasn't really thinking it could be a fuel pump issue, but with over 210,000 miles anything is possible. Also, it sometimes dies when the car comes to a stop with the A/C on...but this doesn't happen very often.
We have a poorly maintained 2001 Dodge Intrepid 2.7L with 155,000 miles on it. Over the Christmas break, we left it untouched in the driveway for a month. After that it wouldn't start without being jumped off, and the oil light flickered when the car idled. We had the battery, alternator, and starter checked at a local shop; all of them checked out fine. Nevertheless, the car wouldn't start without being jumped off. It would click once, and then nothing. We also noticed it was overdue by 2,000 miles for an oil change, and thought this may be causing the oil light issue. Since the 2.7L Intrepids are notorious for engine sludge, we added a couple of ounces of Seafoam, drove about 15 miles, and then took it in for an oil change. Now it starts without a jump. So my question is Is there any way that oil sludge (and perhaps a weak starter?) is the issue?
View 6 RepliesIs it possible to temporarily seal and brace up a front windshield that has a crack in it from side to side, due to cold weather, I'm told?

View 2 RepliesAs it was such a matter of time, my fans on my 24v gave up during winter, no big deal as it was a pretty cold winter but now that spring is around the corner, I gotta fix this issue. To they change for the same OEM unit that will die in the next 30k miles.
View 3 RepliesFirst summer with 2014 Passat. We have been getting close to 90 degree days this early in Summer and I have noticed a sensation that I have not had with almost the first year of ownership.
The last couple of days in stop and go traffic I have noticed that when the Radiator Fans edge up to the fastest cooling speed I can feel a vibration in the steering wheel. It is a strong vibration feeling. I had a friend turn off the car while the fans were going full speed. The largest fan on the drivers side seems to wobble as it cost down from the high speed. I am wondering if these fans can be balanced with counter weights.
I have a 2002 dodge intrepid that wont crank over sometimes unless I take the key and keep moving from the start position to the off position ,then it finally engages. I have replaced the battery, but I thought if it was a starter issue, it would click more than once.

View 2 RepliesSo this seems to be a common code that is thrown when you near 100k miles, I'm at 77k .. This thread seems to be the most organized [URL] ....
"Long story short, there are 5 main reasons this problem can pop up, listed in order of likelihood, least to greatest:
1) Coolant sensor
2) Thermostat
3) Bad fans
4) Coolant mixture
5) Water pump "
My issue is that the only ones I'm (probably) able to rule out is coolant mixture and bad fans. My radiator fans do turn on from time to time, so I thought I'd ruled that out (unless it would throw a code for not turning on at appropriate times?)
I heard of a test to turn on your AC and see if they turn on, but my AC hasn't blown cold air like ever, so I don't know if that affects the test (probably not?)
A couple years ago I had a shop replace the original thermostat with the new one, or was it the coolant sensor, or both (ugh, I don't remember!) That leaves thermostat, coolant sensor, and water pump.
I guess my main question is is there anyway to find out which it is between these 3, without spending so time, money, parts etc? It doesn't seem the coolant sensor is easily accessible for one.
My car has been really slow recently but I also need to change the spark plugs, I'm doing that this week. I cleared the CEL/P2181 code and it returned a few weeks later,
I'm starting to change my mind about this car being easy to maintain/reliable, I'm always on time with maintenance and with only 77k miles on a 2004 car.
