Just got my JDM built motor and in the back drivers side there is a freeze plug where on the stock motor there is a three prong (? temp ?) probe I think that is what it is that fits into that hole with an O-ring seal. I assume I need the probe in the new block but how do I get the freeze plug out?

I use a screw driver and tap it in on one side once it starts to go in tap one side more than the other and it will start to flip on its own. Then grab it with a pair of needle nose pliers and your done. If you decide to go back with a freez plug than you must use some RTV sealant on the plug than tap it back in using a sockett that fits inside of the freez plug.

Hope this helps

Sauvy,

I guess I am just afraid to knock it into the engine or is there a lip on the inside, there does not seem to be on on my stock block.

By the way thanks for the reply.

Sauvy,

Did just what you said and tapped it on one edge til it spun then pulled it out with a pliers,

Thank you very much now I can proceed with the engine install. You just made my weekend.

Before you knock out that freeze plug - STOP

Is this three pronged fitting encased in a light brown rubber bush and fitted to your original engine block just above oil filter ??

If so it's not a temp sensor but the block heater - installed into motors built for very cold climate.

There will be a thick flat twin cable leading from this to a two pin US style plug for mains hook up.

If you dont use it leave it off and dont remove core plug.

I put the freeze plug back in, Ricki F-150 you were correct it is a block heater so I pulled it out along with the wiring. Thanks

Both of my 'L's have had them.

My 2000 one had it wired up so you just plugged a lead into a socket located in the lower grille, used it during cold weather so truck was warm from startup.
Till I forgot to unplug it one day and went of down the road with 20ft of cable following me

My 2003 had one but I removed the hook up cable as I did not intend to use it. My JDM built block does not have one.
I think all North American built ones have this heater fitted.
Common on trucks sold in areas where the weather gets real cold.

Good luck with the install of the new motor.

 

Thanks for your help the install is going well now. I would have liked to see you driving down the road with the cord following you must have been very funny.

Yeah it was untill it wrapped itself around the wheel.
After that it was history.

Still never broke out the plug & socket in the lower grille.
Just ripped the wire to shreds.

We have 230- 415v v mains hear so if your gonna hook up your engine heater you need a drop down transformer.
I have 110v outlets in my garage from a trans for power tools which are also used on site, but only used block heater a few times as was a PITA removing & replacing plug.

What built motor you got?

I have just finished installing my JDM long block & BTS trans, sounds awesome and fired up 1st time - no leaks or any problems.
Just waiting untill Monday so I can download tuning and start the break in process.

Running Mag Powers but must admit that new Whipple set up looks good too.

 

I got a JDM motor also with ported heads and turbo cams. It will take me a couple of week ends to get everything installed but I can't wait to fire it up also. I started this whole engine/turbo swap thing back in Sept. It's been a long time coming to fire it up.

Did you remember to use RTV on the plug when you put it back in?

 

AH! Good point.....

 

There did not seam to be any on the plug when I took it out. So no I did not. If I do need to put RTV on what type would I use? Grey high temp stuff?

As you have not installed engine yet I would insert a brand new freeze plug to be safe as it's real pain up the backside to get to it afterwards if it leaks.

Not worth the hassle if you dump your coolant on a 1/4 mile run or at wot along some remote part of nowhere.

 

I would do as Ricki suggested You can use the blue or I usualy use the black RTV.
Never knew about the heater thing I live in Michigan and we did get that option here?

God Bless,

Suavy
