Default Hard Shifting, Cooling Fans Running All The Time

Anyone have a suggestion what would causing this ? This started today when I was picking my Mom up to take her somewhere. I turned around and the fans can on and it started banging into gear and shifting hard. The cooling fans also run all the time now as well. My Son's '03 L200 did this when the cat got plugged. After driving it around a while it would go back to normal (on his car) but then start again after time. I've been also getting bad gas mileage the last couple months but seemed to have plenty of power tho. I did smell unusual fumes on acceleration at times. That may signal a converter issue. But the shifting and fan issue, I don't understand. 184,500 mi. T.Y.

What temp. is the engine running? If it's low, it will cause the fans to run at high speed along with hard shifting. Normal readings are 3/8"s to 1/2" up on the temp. gauge.

The cure is to replace the thermostat. A easy job on the 2.2 not so on the 3.0.

The smell you mentioned could be the cat going south.

Default Re: Hard Shifting, Cooling Fans Running All The Time

Chaz9496, there may be hidden issues when the cooling fan runs even if coolant level is correct and the engine isn't overheating. To be sure, does the temperature needle move to the same position before the fans turned on or lower since the fans are cooling with temps lower than normal? Your memory counts about where the temperature needle was positioned before the constantly running fan issue.

The hidden issues about fan running when it shouldn't may be one of several other issues unrelated to the cooling system; battery near its end of life and straining the alternator, catcon blockage with a high mileage engine and any other faults. Sometimes when an fault occurs, with or without an error code/check engine light, the engine computer is crying for attention by turning on something that isn't supposed to turn on. The problem may not be obvious like a faulty thermostat or temperature sensor. The best way to determine if a temperature sensor or thermostat is faulty is to connect a reader and display actual temperatures from cold startup to fully warmed (ambient to operating temps).

The xmission acting up may also point to battery/alternator/drive belt issues since the electronically controlled xmission relies on a steady source of power, around 14.5 volts. Voltages below 13 volts may point to the electrical and/or drive belt system.

The temp is at normal range. Just after the time it started I was driving it just about 5 minutes before. No time to cool down. It was about 70F outside at the time. I'd just moved it from a parking stall around to my Mom's door at her apt. Anyway, after about 2 hours later it was back to normal. This did the same thing with my Son's with the bad converter. I scanned it tonight after work and no codes showed but now shows a Service Engine Soon light which this has never came on before since I've owned this car. The fans are off and normal shifting. Odd.

As mentioned above in my reply, the temp is at normal range. The thermostat was replaced last fall. Should still be OK. Don't know whether it was coming from the car what I smelled or from another source outside. It didn't last long whatever it came from. A lot of burned converter smell's last a while in the vehicle with the windows down or up, in which this case the two fronts were down.

Default Re: Hard Shifting, Cooling Fans Running All The Time

Chaz9496, rb6667 mentioned possible catcon going south. With your experience having one fail and seeing symptoms, this is another consideration. Catcons give varying symptoms; rotten egg smell, metal rattling noises under the car, intermittent lack of engine power or complete lack of engine power. When a catcon disintegrates internally, the porous ceramic brick substrate normally self fueled to burn off exhaust byproducts to create harmless gases and moisture, can crumble to block exhaust flow. A disintegrating catcon can choke exhaust flow or allow contents to rattle around and create intermittent exhaust blockage resulting in odd engine power. The car may drive fine one moment then suddenly cannot accelerate or shift with xmission problems appearing out of nowhere then as suddenly as problem appear, disappears with zero problems. Catcons are solid bricks of porous ceramic substrate containing platinum to allow unrestricted exhaust flow until it falls apart internally. A blocked catcon can be difficult to determine.

The quickest home diy test for catcons blocking exhaust flow? Remove the exhaust manifold mounted O2 sensor (upstream of the catcon) for an alternate exhaust path. A soup can diverter may be needed to redirect hot exhaust gases from melting nearby plastic. While loud, drive around and see if engine power returns and xmission shifts normally.

So I was servicing my a/c on my L200 and forgot to connect the three prong sensor going to the air intake. It had the same symptoms youre describing before I pulled over and connected it. It took a few miles before it was back to normal.
