Coolant leak on 7.3

[freeride707]

Ok I didn't get a 7.3 to have coolant leaks haha but I woke up this morning and found a puddle if coolant under the front ofthe engine. Looks like is coming from behind or above the crank pulley. I didn't have time to find out where but my guess is the water pump. Truck only has 91k on it so it shouldn't have gone out yet. Any ideas

I wouldn't be surprised if it is you water pump... Mine went out at 120K two months after I bought it...

Damn that's what I was afraid of. From what I've read here. An internal seal in the pump goes which causes it to drip. Which is what mine is doing. Only a slow leak. But I'm scared to drive it.

Ok I got a new pump and I'm going to try and get it done this afternoon. Any thing I should be careful of. I've never replaced one on a SD. I'm assuming I have to pulle the radiator and intercooler?

dont break any of the bolts on the water pump,i did and it was a mess!! it should be pretty straight forward though.It prolly is leaking from the weep hole,which is letting you know the internal seal has went.My buddy drove his like that for a month but ive heard they could go that same day as well.soak those bolts in pb blaster,goodluck>>>>brian

better than mine.. it went and just dumped a ton of coolant everywhere. had to get it on my lil car trailer and take it over to a buds.
change to an ELC Coolant if you already havent and the only thing you need to take off is the fan and stuff around it haha. not hard at all.

Yeah no rad or intercooler removal, nd you can use an air chisel to knock the fan nut loose...
and mine went out at 110,000 miles. Two weeks after I bought it - I was planning a coolant change so it just hurried things along.

Ok well my @&@)$$!"**}% fan nut won't budge. I cant get a good hold on the pulley it just keeps slipping. And now the damn wrench slipped and I sliced my hand pretty good on the fan. Needless to say I'm pissed off. Any other methods of getting that nut off? Seems like everytime with this truck what should take 3 hours takes 10 and what should take a day takes a week. I NEED my truck by tomorow afternoon so it's got to be fixed.

Use an air hammer with a chisel point on it. Turn the engine... see which way the fan turns and then knock the nut the opposite direction with the air chisel. Works like a charm. I was reluctant at first too, but it was the ONLY way I had to get mine back up and running in a tight timeline. Good luck!

Yep , air chisel . Put it on the top of the nut aiming from drivers to passenger side . Just right on the corner of the nut , usually a very short blast will get it free and then it just spins off by hand .
