2004 3.0 overheating weird problem
I have a 2004 3.0 ranger that i use to deliver a mail route, so its lots of stop and go driving. late last summer and now as its getting hot here, after a couple of hours on the route with the A/C on the temp. gauge will run far right to the hot side, but when i either turn off the A/C or drive some distance without stopping it will go back to the normal range. Truck has 165,000 miles on it and runs fine otherwise. What could be causing this? I cant go without the A/C,nor do i want to burn my engine up. You can jiggle the fan and its got a little bit of play, co[worker said i need new fan clutch and that might be the cause of the overheating. True? Any other ideas/suggestions? THANKS!

Re: 2004 3.0 overheating weird problem
My first thoughts... yes the fan clutch at idle may be slipping to where not spinning fast enough... as to when driving, it has a faster pull going into the slippy clutch to still spin the fan faster... also, the A/C has a clutch that can cause over heating if its got a lot of drag/ needing replaced. Its a hands on fish out problem... I would start by draining the radiator, and doing a flush first... then if not solved, go to the fan clutch.... Hope you get it solved! Good luck!

Re: 2004 3.0 overheating weird problem
Thanks for the reply JOHNHENRY, i recently had a coolant flush and the A/C compressor was replaced last month, i assume the clutch you speak of is part of that? Anyway, am getting the fan clutch done this weekend, i hope thats the problem.

@JohnHenryEdge
OK clarify this for me a dragging ac clutch can over heat a 3.0 Eng? The whole eng? you are talking about the AC compressor clutch? correct

Dragging is = to a clutch not 100% functional... having some drag. Any A/C clutch being faulty can overheat any vehicle, break belts, cause stalls,etc...

Re: 2004 3.0 overheating weird problem
I would agree JohnHenryEdge, my first thought is the fan clutch has gone bad on the radiator cooling fan. I have had this problem on other vehicles in the past. This is a fairly common thing and relatively cheap and easy to replace.

Re: 2004 3.0 overheating weird problem
The AC clutch would be wrecking belts if it was bad, not overheating the engine.
Presuming the cooling system was properly refilled when you had it serviced recently, and since it cools back down once the ram air through the grill picks up again, I would say the fan clutch is most likely.
The AC is exacerbating the problem because it basically pre-heats the air before going through the radiator. The AC condenser is in front of the radiator so the air blows through it and is heated up, then blows through the radiator already hot. If the fan can't pull the volume needed, it's going to overheat.

Re: 2004 3.0 overheating weird problem
Well let me clarify this for you I'm going to explain it to you so maybe you will understand this. Clutch DRAG is contact between the drive and driven member. 0 % is full off to 100% is full on no slippage. In the off position there is an air gap between the two plates so it will NOT drag which would make it overheat. DRAG means the two plates are having some contact in what should be the full off position. Depending on the amount of drag it can be slight amount of heat or a lot of heat ON THE AC CLUTCH ASSY or even the compressor rotating like the clutch was engaged. That's the worst that usually happens the clutch gets damaged from the heat. It could result in ac clutch seizure, failure, fire or complete destruction of the ac clutch assembly. If it did it COULD lose or break the belt and the belt could take out some water hoses resulting in the engine overheating. That’s is the only way it could ever happen and I would think the noise,smell or smoke/ fire and noise would alert anyone to the fact there is a problem a long time before the engine overheated. Like the alt/chk eng light coming on the instant the belt flew off. Thanks Fireranger i just don't want this guy going down the wrong path and just wastng time and money

LOL certainly does make you wonder don't it. I have seen things that would make you just shake your head. One time they towed one in that was so badly overheated that the y pipe was burned completely off the manifolds and was dragging on the ground. Have a good night

Re: 2004 3.0 overheating weird problem
Well, no that isn't what you said. You said the AC clutch dragging could overheat the vehicle, among other things. That is not true at all. The AC clutch will do other things. Overheating the vehicle is not one of them. A broken belt, resulting in the water pump not turning, will result in the vehicle overheating. But clearly this has nothing to do with the OP's situation. He hasn't been driving around without a belt for the last 8 months.

Re: 2004 3.0 overheating weird problem
Do you really want to engage in this debate? Ok. Fine. This will be fun.
First of all, nobody cares how long you've been working on cars or what your job is. You are not impressing anyone. Especially when you provide bad information.
Secondly, your long rambling reply does not make you look smarter. Most stop reading after the first few babbling paragraphs. If you want to help him, then provide correct information based on his description of the symptoms. Not some mile long rambling copy/paste job, or bad advice.
Yes, you copied and pasted that, posting here as if it was your own work with no credit to the author or site, also known as plagerism. You found it here > http://ezinearticles.com/?Top-5-Reas...-Car-Overheats and also here > http://www.sanden.com/index.php?tag=clutch. Congrats. You know how to pretend to be a mechanic...

You replied 20 minutes after the OP posted his question. Of course nobody else posted before you. Your attempt at making it look like he was left hanging and you came to his rescue is total BS. Your attempt at impressing us once again, also total BS. And your snappy timely advice was wrong, which makes it even more comical. So far, everyone else that replied has been far more helpful than you Mr Hero.
BTW, nobody was degrading you. When someone posts incorrect information, it gets corrected. It's nothing personal. I've been wrong before, and I said "oh gee, you're right, good catch." Sadly, you decided to take it personally and insult everyone else trying to provide this guy the help he needs. And you've made yourself look like an ass in the process. Nice job.

Nice job. Editing your post to make it look like you didn't say the things you said to dig your own hole. See ya.
