Icon4 Overheating / accelerator hesitation

Well, first of all, for the past couple of days, my ranger has been running a little rough. Lately it seems like if I'm only giving it a little bit of gas, it starts jerking and doesn't stop until I let off completely, then it thunks and it is fine.

I was wondering if that might be related to the 4WD since I've been using it often on my snow covered driveway, but it could also be a transmission problem (it's an automatic), or it could be misfiring...I'm not really sure at this point.

On top of that, I got home from work tonight and I left it idling in the driveway (with the heat blasting) while I went in the house. When I came back out, I smelled boiling antifreeze, and saw steam literally billowing out from under the hood. I jumped in and shut it off, and noticed that the temperature gauge was at 90%, nearly pegged at HOT.

I left the truck in the driveway to cool off, and it's dark outside now. I'll have to check the oil and coolant level in the morning. I hope I don't discover that I have coolant on my dipstick!!

My question is, do you guys think these two problems are related? IF the truck was misfiring (and I don't know that it was at this point), and I'm losing coolant with no signs of a leak, doesn't that mean I have a cracked head or a head gasket failure?

If my coolant level is okay, then I'm going to check out the fan since the truck didn't overheat until it was parked (no air blowing across the radiator). Otherwise, I'm not sure what could be causing any of this. The truck has over 225,000 miles on the odometer, and other than a faulty starter and a new battery at the beginning of this winter, it has had no mechanical problems at all!

I'll check out the oil and coolant in the morning, but for now, I thought someone might have an idea I didn't think of? Anything at all would be helpful!!

Thanks in advance,
-Dave

Hello Dave,

On problem no 1 your description would seem ignition related to me. That is all except for a "thunk" when you let off. Donno about that?

No 2.. is most likely the original thermostat. With that many miles I'd very thoughly flush the coolant system and put in a new stat.

Thanks for the help! I was starting to think the same thing. I checked the oil and coolant and discovered the fluid levels were fine, and are not mixed at all, so there does not appear to be a head gasket problem.

I'm giving the ignition a thorough inspection tomorrow and I'll check out the t-stat, also. I'll be doing an oil change and a coolant flush as soon as all this is taken care of. Thanks again!

-Dave

Icon8 Update

Well, I never did get a chance to fix the coolant problem; it didn't act up again for a few days (Probably because I didn't want to leave it idling at all until I got a chance to investigate.) I was planning to look at it Tuesday after work, but I never made it home....

I was driving home from work and all of a sudden white smoke started coming out of the exhaust and the transmission started slipping. I let off the gas, and after the rpms dropped back down, it caught again. I made a left turn at a light, and when I started to gently speed up again trying to make it to a nearby parking lot, I had no gears at all, and I coasted to a stop right in the travel lane. Reverse, O, D, 2, L, were all gone, I even tried it in 4WD with no luck. Smoke/steam started coming out from under the hood (the engine was not overheating) so I turned it off. While I was waiting for the tow truck, I noticed trans fluid leaking out of the front of the transmission, which was overheating (hence the smoke/steam). I check the oil, coolant, and trans fluid levels everytime I get gas, and saw no indication of a problem other than the hesitation/thunking I reported earlier, which I thought was either ignition-related or an issue with the 4WD transfer case. Apparently, the trans was the problem the whole time.

This weekend, my mechanic finally got a chance to look at it, and the remaining trans fluid had completely leaked out by this time. We filled it back up again, but still had no luck getting it to move. So he tore it apart and told me that it's going to have to be rebuilt or replaced. A rebuild's going to cost me around $1500-$1800, and the truck's worth roughly half that amount.

So it's going to sit until I decide what to do with it. I really don't feel like dumping 2 grand into it with that many miles (230k). I'd like to pull the motor and drivetrain out of it and strip the interior and just send it to the junkyard. I can keep the spare parts for my '89 Bronco II, just in case. I was planning to sell this and buy a newer truck (I found a maroon 3rd Gen STX at a nearby dealer in MINT condition - it has a fully functional OHC and EATC complete with an Explorer Limited steering wheel (temp/audio controls!!) all installed by the previous owner, and the dealer doesn't even realize that's anything special!!) but now I don't know if I'll have the money for that truck...

Anyway, sorry to ramble on, I just wanted to let off a little steam. I was not happy when I found out all of this. (Guess I know why it was slipping when shifting now....)

Thanks for letting me vent a little, I'm going to go work on the GTI for a bit, that usually makes me feel better. At least the Ranger's not my only transportation....

-Dave

I tell you what, any ranger Ive gotten has been because of tranny (usually needing replaced) and it has 200-300k miles on them and the engine works damn flawless. Tell you what, thats getting your moneys worth!
