I thought the T-stat i got was an 87 degree thermostat.

While im driving the needle will stay steadily just a hair past the 2nd last white line on my gauge (so, one line hotter than middle)

I have this terrible feeling all the time that my dash is about to buzz but my oil temp is fine. it's a little warm i guess? 180-190F roughly.

Are there T-stats for our beauties that will open at like 95? or something.

Anyone else with a gauge that reads as high as mine?

The temp light no longer flashes now a couple hundred K's after rebuild which pleases me. But now the batt light is cooonnnstantly on. :roll: go figure. Perhaps its the V regulator which i will hope and pray for.

I have an 87° thermostat in my gasser. This is where the needle rides.

I've seen thermostats listed that are 82°,87°,90° and 92°. I used to have a 90° in mine and it rode roughly straight up and down.

I wouldn't worry too much about your oil temps as they sound like they are right in the ball park. Do you have an oil cooler?

I have an oil cooler that i haven't put in...
This is where MY needle resides and sits very steadily under heavy and no load..

I wouldn't worry about it too much. Those are 20 year old gauges/wires/senders. Mine runs just on the other side of that white line Ed, and it's always happy.

Get a real gauge and see what's what.

my gauge sat near where you point to ed when i had a 'faulty' thermostat. i should have checked the opening temperature before installation. when i finally ripped it out and tested it, it was opening at near boil :shock: so i installed an '87 and it sat just below halfway, and was running fine.

Dang man. I tested mine first to see IF it opened ... i didn't test at what temp.

It's a brand new sender sending to the gauge so ... perhaps the T-stat is junk? I don't really want to drive around and wait for it to get stuck closed

THAT would suck. Thanks guys.

It's possible. I had one that was dead straight out of the box. :evil:

rip it out and throw it in a pot ED.

a Good project. Lots of fun

My friend who is a Mastercraft certified mechanic put a Tstat in upside down on one of his own

I let him hear it all the time, becuase a friend of ours caught it before he stuck the engine in.
Every one of my diesels and the GTI runs exactly where your gauge did though...I think it is the guage, and that is why I am going with something with #s on it for the TD. #s usually don't lie. Not saying that these do, but there is no way to tell what your coolant is at. The line you have could be 220 degrees or it could be 180 you just don't know.

Yes I agree. It is worrying though.

Will the coolant light start to blink above a certain temp?
I blew a HG before the needle hit the last line once and im very afraid of that happening again. The oil doesn't get too hot. And I can't hear boiling under the hood after shutting it off.

i doubt the coolant light will blink until the gauge is the whole way over. when my engine overheated i don't recall seeing it blink... but it might have.

should i get a 70, 80, 87 or 92 T-stat?

With summer coming up... im going to say definitely not the 92.
70 seems really really low.
debating between 87 and 80...

I may want to go on some road trips which would include going up the coke. (BC'ers know what im talking about

)
In THAT case I'd be more comfortable with an 80... but the different between 80 and 87 is so large... i'd really like an 84 or 85

hahahah
87 it is i think but folks, please include your input. Would 80 be too cold for fuel economy sake?

jtanguay · « **Reply #13 on:** March 23, 2009, 12:13:04 pm »

80 wouldn't be too bad, but i'd say go with '87 + a coolant temp additive. that will keep your temps very stable.

Smokey Eddy · « **Reply #14 on:** March 23, 2009, 12:37:08 pm »

Cheers man, i'll do that

Mine was an 87, it must be faulty.
