Derby: The diagram show the circulation of the coolant when the pump is moving the water. As far as the up then down comment... It will go up until it reaches the thermo. At that point the heater continues to heat water and the heat has to work down backwards because it has nowhere else to go...

Here is an interesting article about CARC and it's health benefits:wink: Chemical Agent Resistant Coating Final Environmental Exposure Report

Didn't you say that you went from the back of the block where the drain is to the water pump? You have a system that circulates the coolant through with a pump. You completed the circuit by running from block to pump.....it then runs from pump back to the block through the oil cooler... One big...

What are we supposed to be looking at? I do not see anything that I did not already know?

Yes if the thermo is in backwards:wink: On most trucks I would say that is not the case. If you leave it plugged in for a month straight it might generate enough heat to work is way around to the back side of the thermo and open it....I am betting not though because it will be much easier for...

Refill the master cylinder and start the truck up. Pump the brakes until you think you can't pump anymore then keep pumping them.... If you have no pedal after 15 minutes or so of pumping check your fluid and see if it went down.

Depends on the style. Usually they have a nut on them that when tightened it expands into the space. Others have a clamp that grips the inside. Freeze plugs come out very easily. They provide a weak spot in the block so if pressure builds from water freezing or steam build up it blows the plug...

I use the term rise loosely in order to make the point. Do you know how thermosiphon works? When water is heated the hot water becomes lighter than the cold water and "rises" to the top..... That is why the collection tank on a thermosiphon hot water system is placed at the top of the system...

I am done debating this with you... You may want to take a look at the TM page 6-39 and have a look at the hole in the back of your water pump... it isn't supposed to be there. For future reference in regards to centigrade temp conversions... It is impossible for Fahrenheit to be lower than a...

Looks good. What made you decide to go this route over putting it into the water pump?

In order to better explain the cooling system in relation to block heaters I went over my truck and made a video. This should help people make a more informed decision about what type of plug in heater to use and where to locate it.

I have nothing against the wrong color. I am just pointing it out if his goal is to be historically accurate, it would be the wrong color. Another thing worth mentioning is to take precautions when sanding CARC. I have seen an MSDS on it and it is nasty stuff. Wear respirator etc.

The air pack has nothing to do with the lack of fluid or brakes.... Even with a bad airpack your hydraulic brakes should be working. Something else is wrong.

Sharp looking yes, but are you interested in maintaining historical accuracy? I could be wrong, but that looks like a gloss olive which would have been painted on a truck of the 1944-45 era. Not 1960-70s era.

Usually they are installed downward, but as long as it is not touching it does not matter. You just need to make sure that it will seal properly at what ever angle you put it at.

Because some will assume that it is about -40 below instead of "googling temperature conversion". It is relevant in a post about start up in cold weather that we are all on the same page rather than some thinking that somebody is starting a truck with a block heater at -40 deg. I put it in...

I have seen it done that way too, but I have a hard time remembering something if I don't understand how it works. I understand the adding or subtracting 32 and the multiplying or dividing by 1.8.... I have always been unable to figure out the multiply and divide by 5 and 9?

I posted for the benefit of those who do not know how to do the calculations...like TM:wink:

F= C( 1.8 ) + 32 -28 (1.8 ) +32 = -18.4 F I am a nurse... we do these calculations all the time:wink:

-28 C, that is what, about 18 below zero F. ?
