Re: So How Hot IS your Vette (Southern Comfort)
Usually stays in the high 190's or low 200's. Very rarely goes over 210, unless its a very hot day, and I'm in very slow moving traffic. Cools right down as soon as I start to drive along. :yesnod:

Re: So How Hot IS your Vette (Southern Comfort)
I just replaced the radiator 2 weeks ago it runs a steady 200 like its nailed to that temp. Before it was all over the place up to appx 230 a lot of the time. A tip to newer vette owners...if its hot out, the coolant temp is high...turn on the AC. Sounds silly I know but that cuts in the secondary fan full time and it makes a big diff. At least thats how it is for my '91 (other years may vary, dont try this at home. This is an actor pretending to be a vette owner giving good tech advice, yadda yadda yadda).

If traffic is especially bad, she'll go a little above 200, like 205 max.
Otherwise she stays in the high 180s, low 190s. This is oil temp.
Coolant is always 10-15F below that.

Cruising in the city at 30 MPH or on the freeway ar 70 MPH the Vette runs pretty consistently at 200 F.
In stop and go rush hour traffic anywhere between 200 and 228. 228 is when the fan kicks in and the temp drops quickly.
These cars do run hot in the summer.

Re: So How Hot IS your Vette (LT-4 CE)
Recently I took a garden hose to the backside of my radiator (after wrapping my opti-spark, of course). After washing out a year's accumulation of dust, sand, butts, etc, it runs a LOT cooler. How much? Yesterday, driving around with an outside temp of 93, the engine was running at ~178! Cool = powerful!

Re: So How Hot IS your Vette (MTVette)
I wish I knew- here's a story... someone rebuilt my motor, and put the heads back on the wrong side. so the guage sender is on the wrong side, and the block-off is where the sender wire ends. and it seems that NOBODY in new york can find the part number for the gauge sender. wtf :banghead:

If you know what you're doing and your cooling system is in good shape, there's no reason your C4's fans to ever come on even if you're running higher initial timing than stock. Well, unless you are cruisin' the Gobi dessert in the middle of summer or worse yet, sitting in the drive-thru line at the local choak n' puke for extended periods (if you engine is extensive modified, this doesn't apply).
My fans come on at 200F, lower than normal factory temps and still the car hardly ever sees over 200F. I cruise the freeway in CA at about 155F. No thermo. But I don't advise doing this if you live in one of those states with rotten weather.
Hey Caratemymoney,
By looking at the pic in your sig, I think you're over-feeding it!

Re: So How Hot IS your Vette (SurfnSun)
Running around town with or without a/c is typically 195-200; give or take four or five degrees. Parking lots and stop and go traffic can see temps reach 225. The main comes on and she cools right back down. Driving down the hiway with A/C on...190 all day long! Making the aux fan functional was the key. I'm thinking she's working like she's supposed to. :cool:

Re: So How Hot IS your Vette (MtlSphere)
Mine hits 228 to 230 before cooling down to 220, then right back up again. See my post:
