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?

Re: [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. I have to put a 180 back in it tonight. Tom - To Unsubscribe please visit www.chevelles.net/list.html To start a new topic, send mail to: [EMAIL PROTECTED]

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.
