Re: [Chevelle-list] Thermostat ?'s
Krister- The hotter you run your engine, the more efficient it gets, which is why new cars tend to run between 200 and 230 degrees. Same reason Nascar runs theirs so hot. On the other hand a cooler engine with a cooler intake charge will tend to make more power. I was taught to drill a hole in the flange of the tstat years ago by a guy who had been wrenching since dirt was new. It does 2 things: When you do the initial fill of an engine with coolant, it allows the air to escape while the coolant comes up under the thermostat. Without coolant on the thermostat to make it hot, it may not open at all and seriously overheat your engine. The other reason is that each time you start your engine up cold, the water pump is pushing coolant out the bottom of the pump, up through the radiator through the upper hose and against the tstat. Having that small hole there allows the pressure to release somewhat, making it less likely to blow a hose somewhere.

Re: [Chevelle-list] Thermostat ?'s
All 66 V8s w/o A.I.R. came with 180 degree stats, those with A.I.R. came with 195 degree stats. Cylinder wear can occur with too cool an engine as well as too hot an engine. Published optimum performance figures I've seen for water temp is between 170 and 185 or so and optimum overall operating water temp is about 180 to 200. If it runs fine now and doesn't overheat with the 195, I'd use the same. With summer coming on, the 180 may give you a little more buffer zone against overheating when caught in traffic if that's a concern. I've heard of drilling a hole in the stat, either 1/16 or 1/8, especially on a big block when the bypass hose is removed. Many new cars come with a bleed hole (or holes) in the stat to avoid trapping air. Drilling a hole is free and couldn't hurt if your replacement doesn't have one. You can do some research on the web and, for the price of a gasket, remove the stat and drill a hole in it. People will say they've run stats for years with no stinking hole in them and never had a problem. People used to drive on 2-ply/4-ply rating bias tires too but technology moves on. :*) Dale McIntosh http://www.chevellecd.com 1966/67 Chevelle Reference CDs ChevelleStuff.com http://www.chevellestuff.com ACES #1709/TC GOLD #92 http://www.chevellecd.com _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, April 26, 2007 3:43 PM To: Chevelle List Subject: [Chevelle-list] Thermostat ?'s I am replacing a leaking thermostat gasket and will replace thermostat while apart.

Re: [Chevelle-list] thermostat question
Unless you live in a hot climate (which you don't) a 180 thermostat is fine for the street. However, if your cooling system currently is at 210 the thermostat alone won't fix it; it'll open earlier (do you have a 195 in there now?) and slow the temperature ascent but eventually it'll still reach 210. Have you verified that this 210 reading is accurate? Factory gauge or aftermarket? How old is the sending unit? GM gauges work based on resistance and if you can locate the resistance scale for your car (a factory service manual might contain it) you can use a combination of resistors to check the accuracy of the gauge. A fan shroud always helps with a mechanical fan but I don't know if '66s came with one from the factory or what your feeling is regarding the addition of one. I personally like fixed-blade fans used in conjuction with thermal clutches. The radiator isn't very old, is it? How long has it been since the system's been flushed? Brad O.

Re: [Chevelle-list] thermostat question
If it runs at a constant 210 a thermostat will do nothing for you if your current one is operation correctlly. Radiator and water pump(pulley) would be where to look for cooler constant temp. I agree that most times the radiator is at fault... whether is is too small, old, partially blocked... etc. Mikey _ Find a broadband plan that fits.

RE: [Chevelle-list] thermostat question
That's a good point. Assuming the radiator is good, I would try a 7-blade fan. A restrictor also means that the coolant is staying in the block longer. It may be self-defeating. Doesn't sound like a good idea to me. As Brad said, a shroud also helps quite a bit. You can also have an air dam down below to help force the fan to pull air through the radiator rather than from under the bumper.

RE: [Chevelle-list] thermostat question
Reading what Stewart (a popular name in aftermarket water pumps) says about thermostats: A common misconception is that if coolant flows too quickly through the system, that it will not have time to cool properly. However the cooling system is a closed loop, so if you are keeping the coolant in the radiator longer to allow it to cool, you are also allowing it to stay in the engine longer, which increases coolant temperatures. Coolant in the engine will actually boil away from critical heat areas within the cooling system if not forced through the cooling system at a sufficiently high velocity. This situation is a common cause of so-called hot spots, which can lead to failures. Years ago, cars used low pressure radiator caps with upright-style radiators. At high RPM, the water pump pressure would overcome the radiator cap's rating and force coolant out, resulting in an overheated engine. Many enthusiasts mistakenly believed that these situations were caused because the coolant was flowing through the radiator so quickly, that it did not have time to cool. Using restrictors or slowing water pump speed prevented the coolant from being forced out, and allowed the engine to run cooler. However, cars built in the past thirty years have used cross flow radiators that position the radiator cap on the low pressure (suction) side of the system. This type of system does not subject the radiator cap to pressure from the water pump, so it benefits from maximizing coolant flow, not restricting it. Dale McIntosh

RE: [Chevelle-List] thermostat recommendations?
Dan, Ive always used 180 degree thermostats in my small blocks. Allegedly, a hotter thermostat will offer a little better milage, while colder ones offer better performance. In my not-so-humble opinion, I think 160 stats are too cold for street use, although I know many people do run them. My 400 always runs a little warmer than 180, unless its below 70 degrees out. This morning, caught in that mess on 480 Westbound, where I idled the better part of three miles, my engine never went over 195. I have an electric fan from a GM3.8 FWD. My 72 Elky (stock 350, stock fan shroud) also runs a 180 thermostat and Ive never had any problems with it either, although I dont have a temp gauge. 210 is on the high end of safe. At 220, Id turn the heater on or let the car cool down a bit. As for tips to lower the temp, change the thermostat and make sure the shroud is properly fitted against the radiator. The fan blades should be partially in the shroud. Ive never used Redline Water Wetter before, but have heard of people having success with it on many occasions. Also, while not easy to diagnose, the water pump could be suspect if the impeller blades are corroded away, not circulating as much water as it should. -Dave -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Dan McIntosh Sent: Thursday, June 26, 2003 3:59 PM To: [EMAIL PROTECTED] Subject: [Chevelle-List] thermostat recommendations?

RE: [Chevelle-List] thermostat recommendations?
First of all if this is the stock engine 220 deg is too hot. They originally were designed to run around 190 deg and had about 180 deg thermostat in them. The thermostat is really only designed to inhibit the water flow to allow the engine to warm to the normal operating temperature. If you are running within 10 deg of the thermostat rating then your cooling system is probably OK. Try a lower temperature thermostat first and if you still warm up to 220 deg them you need to start troubleshooting your cooling system. If this is a late model engine then they were designed to run at a higher temperature. -Original Message-From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Dan McIntoshSent: Thursday, June 26, 2003 12:59 PMTo: [EMAIL PROTECTED]Subject: [Chevelle-List] thermostat recommendations?

Put a 180 in it. I run a 180 in my 454 in the 70 and in my 350 in my 86 Cutlass. They both hover around 190 degrees unless they are running hard. I just put a 160 in my Cutlass as a temp fix because the stat stuck closed and right now with the 160, it is running too hot becasue the stat is not functioning right in this engine.

Re: [Chevelle-List] thermostat recommendations?
Not sure what guages you are using to read the temp, but if it is a mechanical one, you might want to test it (it is fairly easy) to be sure the readings that you are getting are accurate. I struggled with a similar problem years ago and then discovered that my guage was reading 15 degrees high and I really didn't have the problem that I though I had. Just a thought.

BTW, the shroud is tight, the fan is inside the shroud, and I recently had the rad. flow and pressure tested... Hey Dave... 480 Westbound?? where on the map are you located??

Dan, I've always used 180 degree thermostats in my small blocks. Allegedly, a hotter thermostat will offer a little better milage, while colder ones offer better performance. In my not-so-humble opinion, I think 160 stats are too cold for street use, although I know many people do run them. My 400 always runs a little warmer than 180, unless it's below 70 degrees out. This morning, caught in that mess on 480 Westbound, where I idled the better part of three miles, my engine never went over 195. I have an electric fan from a GM3.8 FWD. My '72 Elky (stock 350, stock fan shroud) also runs a 180 thermostat and I've never had any problems with it either, although I don't have a temp gauge. 210 is on the high end of safe. At 220, I'd turn the heater on or let the car cool down a bit. As for tips to lower the temp, change the thermostat and make sure the shroud is properly fitted against the radiator. The fan blades should be partially in the shroud. I've never used Redline Water Wetter before, but have heard of people having success with it on many occasions. Also, while not easy to diagnose, the water pump could be suspect if the impeller blades are corroded away, not circulating as much water as it should. -Dave -Original Message- Wrom: GAUTFJMVRESKPNKMBIPBARHDMNNSKVFVWR [mailto:[EMAIL PROTECTED] Behalf Of Dan McIntosh Sent: Thursday, June 26, 2003 3:59 PM To: [EMAIL PROTECTED] Subject: [Chevelle-List] thermostat recommendations?

Well this is the first I've heard of doing it, but it appears that a lot of you do this... guess I'll be doing it too now :) Rodney. 71 Chevelle El Mirage, AZ - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, September 18, 2002 4:39 AM Subject: Re: [Chevelle-List] Thermostat ever since I had a problem with a brand new 'stat, I've always tested them...it save taking everything apart again.

Re: [Chevelle-List] Thermostat
You gotta see the look on your wifes face when she comes into the kitchen and finds you standing over a boiling pot of water checking the water temperature with a themometer. When I say I'm working on my car, she just throws up her hands and walks away. But anyhow, you can easily check the openning temperature on a thermostat easily enough. If you look around the kitchen, you can find all the tools you need to do this...or buy your own thermometer.
