1948 B1B Engine Serial Number

Greg,

Thanks, I'll look for the drain plug and remove to make sure the block is fully drained and then add a 50/50 mix of anti-freeze & water.

Initially, I poured undiluted anti-freeze into the block figuring the full strength anti-freeze would mix with any residual coolant water and provide sufficient protection. Not sure I understand your note that 'anti-freeze by itself doesn't provide a lot of freeze protection'.

How about the heater core? Do you think I should blow it dry or fill with a 50/50 blend of anti-freeze & water?

Not sure I understand your note that 'anti-freeze by itself doesn't provide a lot of freeze protection'.

This note made my face go........when I read it too. Did you mean it doesn't provide as much cooling as diluted antifreeze ?

I think I read that someplace too. i just looked on the back of a gallon jug. 50/50 mix will get you down to -34, 63 % mix will get you to -64. Price of the stuff, use a mix. Should get you all the protection you need.

Yes, pure antifreeze freezes at a higher temp than mixed with water.

Also, if you just pour antifreeze in a non running motor, it will not necessarily get mixed with whatever was in there. For example, nice pure California water may still be in the corners of your block, or the heater core, having little or no protection.

Thanks, guys. CT temperature was 10F at my house this morning. Sure hope that 'pure CA water' still residing in the block or core mixed with some of the 100% anti-freeze I added last weekend! Guess I'll find out this spring when the big thaw arrives.

Does anyone know what the second set of number are on the B1B engine serial number.  My truck is a 1948 B1B, engine serial number T142*4021*  ......I am assuming the second set 4021 is a number meaning the 4021st engine built????

Someone on the truck side will know for sure, but typically the first bit is the engineering code for the vehicle the engine was originally fitted into. In your case that is T142. I am not sure what a T142 was but it may will be a B1B. The second bit is a sequence number. On the car side those start at 1001. If that holds true on the truck side then that would be the 3020th engine built in that series.

Thanks.

The first set is the engineering code and,

yes it is my understanding that the second string of numbers is the sequence number,

not sure of the 'starting' number?
