WOULD ANY OF YOU GUYS RECOMEND A 180* STAT WITH SOME WATER WETTER? ANY PRO'S OR CONS FOR THIS COMBO?

 

I got a 160 themostat. What temp depends on where you live i think.

 

I live near phila pa but what i was concerned about was will the addition of the water wetter cause any problems since it will lower the temp even farther. i figured water wetter with a 160* stat may be too much for a daily driver.

 

Water wetter only helps when the thermostat is open and the coolant is flowing. When the thermostat is shut(around 160 for a 160 thermo) water wetter does nothing. So, your minimum temp isn't going to change from adding water wetter. If it gets real cold, the heat won't work very well with a 160 thermostat.

 

Never had a problem with Water Wetter. I just bought a couple bottles today. They were on sale for $3.99 each.

 

That's the exact setup I use in my car.....180* brass T-stat and Water Wetter..... I like it a lot, but it won't fix your heating issues in the heat of summer; atleast not by itself. I just ordered JET's Fan Switch, which will turn the fan on at 200* as opposed to the 225* stock setting.

What the lower t-stat and water wetter do is slow the process of the heating down a little bit, but it won't keep you from hitting 220*.

Regardless, if you want to really keep your car cool, but still funtioning and not take a big hit in either your gas milage or wallet, then I would suggest using the setup I just described. You could get more crazy...like a high buck water pump or some aluminum radiator, but that's overkill in my book.

 

how much was the t-stat switch???

 

why would haveing ure car running at 160ish effect gas mileage

 

Because of the TBI ECM's reliance on the CTS. The cooler it is, the richer the mixture. I'm not sure of the function of coolant temp to mixture, but 160 is probably still considered warm up by the ECM, so it's going to be running richer, hence worse mileage. You WILL go to closed loop, just running richer than you would at, say, 180, or 195.
My mechanical fan keeps my L05 pretty cool, even at idle in gear with the A/C on. I have a 180 degree stat and while sitting at a light, my temp crept from about 203 degrees to 205 degrees. That's not too bad (it was like a 2 or 3 minute light, too). If I wanted to get my coolant to 220, I'd have to hold wide open throttle for an extended period of time in the summer heat.

 

ohhhh aight i see is this good though if i need the little extra fuel cause after i do headers this summer ill have whole exhaust done.

 

I just ordered the JET switch today, too. Maybe that's why the guy was acting weird (like how many of these damn things am I gonna sell today?! j/k). I got one of those race thermostats too a while back. If it ever goes out I'll be surprised. That thing is beefy!

 

From Summit it's like $38 plus $7 for shipping....something like that. P/N: JET-60600

 

I use a 180* thermostat all year round with 2 bottles of water wetter mixed in the radiator with Water Only since water absorbs heat more efficiently than antifreeze. With the Jet-Fan Switch on a 100* day my temperature gauge will go to about 220* with the air on in traffic.

 

I'm using a 180 robershaw thermo with water wetter and 50/50 coolant/water mix. Stage 2 Stewart water pump and stock radiator, no problems. Oh yeah, and that $20 adjustable fan switch.

 

Just what I need ...What's the part number for that JP? It's reverse flow correct?

 

23123
23123HP

 

i use a 180* stat and half water half antifreeze the temp always stays at 220*. something is wrong with my fan switch though ( i cant find the connector to plug it in)

 

im still confused on one thing so their are 2 fans one can be controlled and lowered by the Cool Fan Switches that they sell in thunderracing.com and the other fan is controlled by the computer which can be changed by buying the power thermostat chip also in thunderracing.com also what else does the power thermostat chip do? anything else special? thanks

 

Thanks JP

 

The ecm (eprom/chip) doesn't control any of the fan operations in TBI equiped f-bodies. The job is done with it's own grounding switch which is a completely seperate from any other system in the car. Think of it as a thermostat but instead of opening a valve it just grounds a wire.
It's located in the passenger side head. Just above the knock sensor.
The "power thermostat chip" doesn't do anything, it's a waste of hard earned money and should never be considered unless you get it for less than $10, even then it does little or nothing or it wouldn't be considered a 50 state legal eprom.
Don't buy off the shelf eproms, they're worthless! Either you spend the $250 for the equipment and software to burn your own, pay a tuner to do it, or slap on a carb and forget about EFI all together. I don't consider those off the shelf eproms an upgrade, I figure it as the single most worthless investment ever assumed to be an "upgrade" and ANYbody that burns their own eproms will tell you the same.
If you're confused about any of this let me know.
Oh yeah, TBI, we only have 1 fan, TPI has the dual fans and yes, they are controlled by the computer/ecm. Both TBI and TPI fans are controled by the a/c switch as well.

 

thanks for the info man, now i know not to buy the chip and just the switch

 

That's why they call them "HYPERCRAP"

 

I installed a switch in that little blank spot underneath the light switch for my cooling fan. I leave it on at all times and leave on my defrost. You can leave the defrost on cool or warm depending on your own comfort. I rarely hit 220 anymore. I use to all the time. I stay around 190 consistently now.

 

me just ordered the fan switch and 160 stat today from www.thunderracing.com,came out to 55 dollars, it definitly was getting too hot and engine running so much ****tier in the heat.

 

oh yea me forgot i ordered the switch that kicks on at 176 and turns off at 166

 

would that switch be too low for the winter, do you guys think the one that comes on at 200 and off at 185 would be better?>

 

i think with the lower fan switch ure heat wont work as good but i dont realy care right now cause the summers going to be sooo hot if its that bad in the winter ill just change it back or get the other switch its cheap enough

 

That's the one I have.....it works just fine.
