These holes???

Yep, those are the holes I am referring to. The factory didn't drill holes in them, the dealers didn't drill holes in them, none of the repair shops drilled holes in them, but the C3 owners feel they need them for some unknown reason. It's just another ridiculous C3 MYTH guys.

I'll say it again in case you didn't read what I posted in the beginning of this thread. With the OEM thermostat my heater began working in about 5 miles and with the drilled thermostat it took triple the distance. The whole purpose of the thermostat is to PREVENT coolant from passing thru it; not ALLOWING coolant to pass thru it.

Air Pockets

Unless the small holes in the head gaskets are plugged Chevrolet V8's don't have any place where air can get trapped. As you fill the radiator coolant flows into the suction side of the water pump then thru the two large holes in the front of the block. The coolant surrounds the cylinders and then it rises up thru the holes in the head gasket then begins flowing foreword where it enters the intake manifold and passes thru the thermostat. With NO place for air to get trapped along the way. It's a MYTH.

A Chevrolet V8? The water passage on a Chevrolet V8 intake manifold goes straight thru from side to side with no place air can become trapped. As the thermostat has a little "bleed notch" air passes thru that notch. As the notch is small it does take a few minutes for the air to pass thru but it's certainly not an "air pocket" by any definition. I have been building Chevrolet V8's for 50+ years and I have never known of any air pockets to exist. If they do exist please tell me where. Now, there is the possibility the little holes in your head gasket had become plugged with rust or other debris and that would slow down the flow of coolant from the block into the heads when you filled it.

As I wrote in my previous post, when I took the thermostat out- the temp didn't go up. When I put the thermostat back in, it overheated (I shut it down before it got past 225*). There was air interfering with coolant flow. Where it was exactly? I have no way of knowing, but it was there. That rules out any plugging up of passages.

It seems to take your limited knowledge to include all generations of Chevy V8s. As we are all used to you, never mind as you aren't worth time.

No Air Pockets In Chevrolet V8's

There aren't any "air pockets" in Chevrolet V8's. Are you learning anything yet?

Do a search for "burping a LS1 cooling system" That means copy what is in between the quotes and paste it into the search engine of your choice...
As your ability to do so is highly doubtable, click this:
burping a LS1 cooling system - Google Search

Last I heard the LS1 is a Chevy V8... Maybe, you know better???

Or perhaps this:"This instructable will walk you through the simple process of "burping" or getting all of the trapped air out of your cars cooling system. This works for ALL Vehicles"
How to Burp your car's cooling system

As usual, you're wrong and we are all painfully used to it..

I know all of the above is above your pay grade.. Which is why you're so amusing..

I was really amazed over how two little 3/32" holes could delay my engine's warm up so much. Most people don't know they are supposed to replace their $6 thermostat every time their radiator hoses are replaced or about every 2-3 years. Instead they have the mistaken belief they last forever and run them until they finally fail; sticking closed and frying their engine. If they would simply replace them when recommended they'd never have a problem.
