Question Alternate Water Temp Sensor Location --> AST

Ok...This topic is actually embeded in another thread I started but I think it deserves it's own thread...

Had my gauge sensors installed yesterday...EGT and Water temps...

My mech didn't want to drill and tap the thermostat housing like I suggested...He said we should do it in the Pettit AST...I said ok...so it's in there and the temps are reading fine...regular driving it reads between 190-192°f, then in trafic it goes up to 208-210°f...

Just wanted to know what you guys thought about that..

thanks again

Pretty bad place for it, it should be somewhere that ALL the hot coolant goes through ALL the time. T'ing into the Throttle body coolant hose would've been a better choice (that's what i did since i was too lazy to tap)

Well I don't know beacuse I don't have it.

but basically it has touch the hottest coolant all the thime.

I was thinking put metal section in the middle of upper Rad hose and pi right there..

that hose is too long and it can be the upgrade too IMO.

Ok..so it's been a day since I have had it installed in that spot and just wy watching it...it's super responsive...as soon as I have been sitting for a while you will see the needle ticking it's way up to 208 from 191...Personally I'm pretty happy with it...

The only place you should have installed the temp sensor was the thermostat housing, this is the hottest spot to measures temps coming out of the motor.I took my t stat housing to a local machine shop they tapped it for $20.

OMG, thats gotta be the worst place to put a temp gauge!!! I'd say your probally running damn near 230 degrees F. in reality. Also, who the hell is your mechanic? I want to know so I never go to him! Are you sure he is a certified mechanic?

Good luck, your gonna need it!



P.S. A new engine is only about 3-4k so you don't really need to worry about it, it's not like its a Lambo or Ferrari engine. I'm sure you can afford it LOL!

Don't know if anybody's tried this before, but there is what looks like a large set screw on the top of the thermostat housing that looks like it could be removed to fit a sensor:


I too am going to install my sensor in the next couple of days, and was wondering if this might be an easy way out of having to drill and tap???

I think the ast is a bad place to put the sensor... it'll give you an approximation of the coolant temp, but it should really be located somewhere directly hooked to the engine's coolant flow, like the thermostat housing. It shouldn't be too far off, though... its just not the best place to put it.

3-4k...is that it? I was thinking that the engine was at least 6-7k installed...what was I thinking? that's like nothing...well, nothing compared to what I was thinking it would cost...I think I will just run the **** out of this one and then get another one soon....thanks for all your help guys!

I have seen engines for sale for about 2k and I figure its another 2k to install, might be a little more depending on where you are located.
