Have not gotten to it yet. My fiance is being induced tomorrow with my first child so my mind has been elsewhere. Ill check it over when life slows down a bit.

Life will never slow down a bit anymore, with a child.

Congratulations! We'll be here when you get back.

Your pic clearly shows the stat is located in the head......not the block.

Long block... Maybe I am old school...


Congrats to the OP on the new child he and his lady are bringing into the world! That is way more important than a car or truck... <3

I'm old school and we did not confuse the head with the block.

A "long block" is simply referring to the head and block assembled together. The term is generally only used during an engine rebuild and installation.

For example, if your head had a crack in it, you would not say "My long block is cracked."

If my head had a crack in it I probably wouldn't be saying much at all....except maybe 'OOOOWWWWWW!!!!' if I were luckier than some.

.....and most re-man motors can be purchased as either a "short" block or a "long" block re-man motor......"long" block includes the head(s).

The XJ stat is in the head, not in the block.

Some of us have head blockage. Maybe it is all of us.

Beats the heck out of me why someone would buy a short block, then stick the old head back on it.

That's just asking for it.

Maybe someone spent extra for specialty head(s) that r still in great shape and don't want to spend more money on something they don't need. There r other valid opinions/options besides yours out there.

Yours are not in that category.

A short block can/could be a valid option even though it may not meet with your approval.

To alleviate some of the arguing, here is what Stant recommends.......

How do you test a thermostat?
A thermostat can be tested by threading a string through the valve and suspending it in a bucket of boiling 50/50 coolant and water. Immerse the thermostat in the hot/boiling coolant mixture for a few minutes; if the thermostat is working, it will fall off the string as it starts to open. Remove the thermostat. After allowing it to cool, the thermostat should close.

.........from their website so there is your answer.

I doubt that most people that know what a "short block" is would stick an old/non rebuilt head head onto a fresh block and call it a day. I agree, that would be asking for trouble.

Yes. Why buy a long block if you are upgrading the head(s) anyway.

I'm not sure I understand the pissing match in this thread.

And once again so there is no confusion.......the thermostat in this application is located on the head.......which is attached to the block......which in combination is commonly referred to as the "long block".......which means that everyone gets a blue ribbon!!!!!!!!! Great job!!!!!!!!!

But in all fairness though, I have only heard "short block" and "long block" used prior to assembly, not after. Not sure if it matters, though.
