1988 P37 7.4L 454 Coolant Capacity

Google is zero results, no results in here. So, I want to replace the coolant after my minor overheat on Labor Day weekend. I replaced it all with water.

Now, I want to drain and replace with coolant. I have seen 25 quarts for the P30 truck with A/C, so is that about what anyone else has found in their RV?

Six gallons and one quart? So this would be 3 gallons of coolant to mix with water?

My VIN says my chassis is a P37

454 4 Bbl. carburetor with factory A/C

Just need to know how much anti freeze to buy.

Thanks in advance!

The most common mistakes made is mixing the antifreeze before putting it in
or using 50/50 premix.
One should pour in straight antifreeze of the amount needed for a 50/50 mix
for the system capacity then add water (distilled) until you reach what the capacity
should be if still not filled add 50/50 until full.
The difference between a 22.5 or 25 qt system is only a qt of straight antifreeze and
a like about of water.
The main reason is no matter how hard you try you can not drain the system of all
fluid.

I drain the radiator. In this case, I'll be adding 3 gallons of 50/50 antifreeze and 3 gallons of distilled water. I'll fill the radiator with straight antifreeze. Start the engine and let it idle. The thermostat will open, I'll keep filling the radiator until the 3 gallons are in the system. After that, I'll just add the distilled water until it won't hold anymore and then top off the over flow bottle.

This is the way I have always done it. This way, all the coolant is in there and any shortage will be with water.

If I read this right you are going to put 50/50 in then add water?
So much for the 50/50 mix that they want installed.
It will be something like 25/75(water or more)

Sorry, straight antifreeze. Mixing it to 50/50. Not premix 50/50.

Then adding water.

The first thought I had was why bother with the antifreeze. Ha Ha
