You guys think I’ll have an issue?

I overhauled most of my cooling system this last weekend. New rad, water pump, inlet(heater) tube, thermostat, and one of the hoses.

My problem is I didn’t tighten down the inlet tube to the water pump all the way and didn’t realize it until I was done. It’s a couple threads in there for sure, but I can move it (spin it) a couple degrees with ease. It can’t spin all the way due to stuff being in the way. There is Teflon on the threads. It is loose though and I have a small road trip coming up.

You guys think it could leak or be a problem?

If you can move it by hand, vibration will be your enemy.
Fixing it at home will be much better than along the road in a pouring down, windy rain storm....

I agree, much better at home, but I don’t have the time to take it all out and tighten it. It’s on a few turns for sure, it’s just not snugged down and can be turned a bit by hand.

Probably will leak

Too bad cannot tighten with it installed

Don’t think it will loosen on road with hose installed holding it in position

See if it leaks and if it does even a little probably have to remove and icstall correctly unless you want to gamble with high temp epoxy spread over/around joint

Mine backed off just 1/2 turn from being fully tight and leaked. Yours might be alright though.

Dang. It hasn’t leaked yet, but it’s only been 3 days. It will be well over a week until I can rip it all out and tighten it again. I was just seeing if anyone else had a similar issue before and how bad it might be.

I hand tightened it because I didn’t want to over due it. It felt tight already. I was wrong.
I guess I’ll get a wrench on it sometime in the near future and give it one more full rotation. Better safe than sorry on a road trip.

Is their a torque number here? I didn’t see one in the FSM. I’m assuming nice and tight and in the right direction to snug up to the heater hose.

Yes. You can only tighten it so far to line up right with the hose.

No torque spec... common sense must prevail...
Tight enough that it can't move or leak but don't break it off...

While it's not the proper thing to do, folks have been known to drive for many years w leaking fluids.... just have to keep em topped off and not let em get low....

I once drove a truck 1000 miles home putting a gallon of water in it every 30 miles or so

I do plan on fixing it right soon.

I also once drove the same truck (a flatbed wrecker) home right after buying it, all night for about 600 miles, with my s-10 on the back running and hooked up to the tow truck w jumper cables so I wouldn't have to spend the night waiting in napa's parking lot for a new alternator....

I wouldn’t chance it. To avoid redoing the repair though, you could cut the heater tube with a tubing cutter then remove it and replumb with black pipe or brass fittings and/or heater hose.

So replace it with straight brass barbed nipple after cutting off bend so can be removed
