fluctuating temp gauge

[992dr]

I was driving home from a little trip, roughly 2.5 hours round trip. While driving home I noticed my temp gauge was fluctuating from 1/4 to 3/4 all in a very short period of time and quite often. Right when it came down to 1/4, it went right back up to 3/4. Did that several times before it simmered down. Then it threw a code . Great

Any ideas on what could do that to the temp gauge?
I still have to get the code read to.

Its a low, very low radiator.
Something I neglected to take care of was that darn heater hose fitting. I had completely forgot about that.
That will be taken care of tomorrow as soon as I get home from work.

Lesson learned, put something off and you are bound to get bit in the asss in the end.

I was just about to say it sounds like you're low on coolant, but you figured it out. Hope your motor's ok.

Thank you, I think my motor will be ok, thankfully.

What I was most amazed about was, the fitting itself. I put a socket on it, thats it. I didnt try to loosen it, yet. The fitting literally broke off, just from putting the socket on it. I was in shock. And boy was I lucky this didnt pop off while driving.
Another thing that freaked the sh*t out of me was, the broken part in the manifold, it came out very easy.
I will have pictures tomorrow. I am stoked how well this went.
Hopefully I wont jinx myself, hah.

That would have been bad for sure! good thing it didn't!

I replaced that fitting with a barb. No more bull crap quick connect. Actually the quick connect never failed for the first 13 years but its gone now!

Yes, that would have been qbad to say the least.

I am very curious to see this. Do you have any pictures? Could you please share?
Thanks


This is the fitting. I was quite shocked at how easy it broke from just putting the socket on. Couldve been a lot worse. That extractor is awesome.

you got off easy. i wanted to do mine when i took the manifold off for head replacement and removing it destroyed the manifold rendering it useless.

Yeah you got off REAL easy ...

My 93 did the same thing, just pot metal threads left. I pounded a big screwdriver into it and turned the rest out.

Well, we'll see how easy I got off. A friend of mine came over to help me remove a welder from the back of my Tahoe. Thankfully he was there for a ride to the parts store. What I am not very keen about is, when I was getting my small attachment for my vacuum cleaner, he decided to use a small pick to remove any debrit from inside and on the threads. Which was fine, the bad part. He was picking at the intake manifold gasket and pulled a small peice out. I'm hoping there is enough gasket to seal, if not. I may be doing my lower intake manifold gasket, AGAIN.
So, as of now, I have not driven it. I will be keeping my fingers crossed on this one.
