Want to install an Engine Block Heater yourself? This guide may help.

I know this is an old posting. I have 2008 Prius and for years, I’ve been wanting to put a heater in and now that I got one I can’t seem to figure out which hole it should go into. What I got for heater was 11813 part number from Etrailers in the USA. There are 3 holes all have caps this heater is smaller than those three holes as I can’t see any other.

Well I can’t get it in seems the thick end of heater is hitting ribs of what ever it’s under there this didn’t come with grease I had thermal paste in a syringe and that wasn’t working so I put wheel bearing grease on it and still I can’t get it in. I think it’s not lined up properly but it again

 

It is see image this isn’t going to work






I just had an idea I sent the image to a friend of mine and I’m looking at the image and I’m thinking why can’t I notch the backend where the plug goes in grind it off so that it can straighten

 

On 3rd Gen the hole is nigh impossible to see. It high up in the block, just below the split line with the head, around the back, and close to drivers side corner.

I would clean off the alternate grease, get some more heat-transfer grease. Don’t apply grease till you’re sure it’s the right hole, trial install, then dab on the grease when it’s almost pulled back out. Then twist it as you’re pushing it back in, try not to scrape off the grease.
The clip on the end should positively click into a pocket, locking it out in place.

if you can find/see the hole, it’s probably the wrong one. If you can easily reach it, it’s probably the wrong hole. If there’s not a multitude of of conduits and brackets in the way, you know…

This is 2nd Gen 2008 That image pointing on first Page mine has no hump where it points to where the hole is I did find hoe on the drivers side of the block. Also I called Brantford and Ancaster Toyota asked for the block heater for 2008 and Brantford told me that is no longer available Ancaster said let me look that up and then said the same thing. I even looked on ebay today and they had one for one of the other toyota looked bit long also

 

I opened my image in one browser window and the one from Green Hokie the image that has arrow
to where the hole is I had stuck my phone camera up there in my car and there is no hole.

 

I do think that the image Green Hokie is same only where he is pointing to is the side of the engine
where I found the hole but heater I got is to long. There is another tread of someone had said they couldn't wire it and you chimed in to him and wonder if he has same issue there is very little space image I the top where heater is hitting.
Waiting for the Etrailer to get back to me as I want to see if I take it on the lathe and turn the top end down a little still be able to plug it in be less of snug I think also I'll have to consider the ground is grounded as the plug seats.

 

There is a block heater available from Toyota. Toyota Canada can get it readily, but Toyota USA not so much, for some reason. There's that old saw about "The Great White North", but I'll take southwest coast Canada over Minnesota, or any north-central US State.

Have you tried contacting a Toyota dealership parts department? FWIW, when I replace the block heater on our gen 3, a few years back, the latest part number was:

PU140-00905

This "may" be the same part used on gen 2, not sure.

A little info on the heat-transfer grease:

Toyota supplied with block heater: NSCG silicone grease G-624
Equivalent to: Novagard Versilube G-624
(NSCG stands for Novagard Silicone Compounds and Grease company. They are now known as Novagard Solutions.)

Good Morning Mendel

I did call Toyota Brantford & Ancaster both said they can't get it anymore to old he said.
I even called a USA company on Friday evening haven't heard from them yet see if they might have it.
As for the grease thermal grease I need to get. I used have thermal white grease for electronics that is more supple than the syringe I got from amazon it was grey thicker grease. My brother said he might have some electrical grease I will go over there when he comes home from work. This hole I found on the drivers side of the block I can't see can only feel I can't get my finger in there to see how deep it is.

I could maybe call Hamilton and London Toyota by chance they would have one collecting dust.

I did call Toyota London and this guy without the vin found one that part number changed when I gave him vin saying they are not available but I was pushing to see if the one that he was able to get if I coiuld making it work his boss was whispering in his ear and he got back and said give me your number will see if we can make this work i'll Keep you posted

 

That's frustrating. I got mine through dealership, in 2019, geez 5 years back now. Googling the part number now I saw out-of-stock. My "fun", installing it:

He told me the vin # its a Prime
yet has no GPS
Just found out what that contraption is under passengers seat it's a Radio.
Took the cover off and QR scanned it was number google showed me Ebay with one
I wanted GPS for it factory but searching on here it involves allot of work to find doner and take and install

Hoping they can pull it off and find me one I said to him he's only one that has looked this much Ancaster did look but came up with no can;'t get Brantford just without looking.

Yeah install is going to be fun from the top you can see it possibly plug it in from the top
but putting heater in you have to do it from bottom to line it up with the hole. He looked to see if
could find the location for it.
