Overheating Problem

Hi, I have a 92 Ford Full Size Bronco Eddie Bauer Edition with roughly 211000 miles on it. I just had an interesting experience where my fan assembly came spinning off of my water pump at 4k rpm taking out my radiator. After replacing the water pump, radiator, upper and lower hoses, and putting a flex fan on in the place of the stock fan eliminating the fan clutch because no one had a stock style fan.

Now when I drive it normally it has no problems, but when I'm driving offroad at slow speeds and low rpm it heats up like crazy very very close to overheating. So I turned on the heater on high and got to the closest road and got up to about 45mph and the temp dropped back to normal. But when I slowed down again the temp went back up.

Now before I replaced everything it had a problem with coolant dissappearing and there wasn't any leaks and now since the replacement when it heats up the oil pressure drops. I don't know if these problems are linked or not but I'm really worried about it stranding me out in the middle of nowhere.

I hope this helps thank you

Jason

I do have the old fan clutch still if that means anything and it was working fine till the incident. Should I still purchase a new one? And the fan shroud was torn to pieces so I'll need a new one. Do you think that is the cause of the problem since the fan is running nonstop? Cause it's also been suggested to me that it's the thermostat.

Well I finally got all the parts in, and as soon as I put them on and went for a test drive it didn't overheat, yay.

But I'm still waiting for the answer to the question about how I find out what size my front axles are. Thanks for your help.

Well I couldn't find any tags but inside the door it has an axle code #19 is that what I'm looking for?

And it was suggested to me to put my truck up on jack stands and put it in four wheel drive and let it spin while holding a 2x4 against it and watch it jump. I did and it bounced like no other. I first noticed it because there's about a four inch section that has been rubbing on the arm (thing) that it runs through that's worn it down a good 1/8 of an inch.

And one more thing, I think one of my cylinders is not getting spark, but my check engine light hasn't come on and it runs like normal. The only reason I don't think it is, is the fact that when I pull the plug wire off the metal connector stays on the plug and not inside the wire, I got it shoved back inside the wire and it sits on the plug like all the others but I don't know if it's sparking.

The reason I ask is because it's my only vehicle, and I need it to go to work, I don't have the funds to replace the wires right now and I want to know if it's ok to drive 4 miles each day till next Thursday.
