what you need a block heater for? -i know what they are for, but i dont see why you would need one?
Block heater is not cooperating!!!
Has anyone installed or had trouble installing a block heater on the 3.4L V6? I found Toyota's part number C0140-02134, but opted to not go with name brand for cost saving. I decided to go with Kat's Heater 11414.
First off, let me say what a pain in the @$$ this was to install....
First, I couldn't get it to go in because of the clearance between the cylinder and the out block wall. For this I had to play with that sweet spot for the bolt and butterfly bar while figuring out that you actually have to insert the heater @ the 5:15-ish position while turning down to 6 o'clock position to seat it.
Second, as I was tightening the bolt, the o-ring under the bolt head would twist and pop out from behind the bolt head. Had to replace that with a smaller more suitable o-ring.
Third, now that its installed, its not flush (guessing because the heating element is right up to the cylinder wall) and leaking by the o-ring. According to Kats instructions, said not to use FIPG and to use a light torque.
I'm half tempted to purchase the Toyota model because (based on google images) the heating element appears to go over the butterfly bar, which in theory should help with getting it in the hole. But cant see how it would clear the cylinder wall.
The 2 attached pictures are the Toyota (from google) and the Kats Heater 11414 which I had.
Input with pictures are greatly appreciated!!

Verdict:
So I removed the Kats heater 11414 and installed a Toyota block heater. The Toyota heater went in effortlessly and without any issues. Highly recommend Toyota part #C0140-02134! I found mine at the local dealer for $49.99. Found others online for $60- $70.
If you look at the Kats heater, the element is too long and is a b*tch to get in with the element too long and the butterfly bar sticking out to far to make the angle to get in. Too many factors and too few sweet spots!
Comparatively, the Toyota brand heater was shorter and more compact with the butterfly bar tucked under the heater element. It also came with a small package of grease to help seal the oring. The cord also came with the cover for the plug which Kats didn't. And part of the cord was wrapped to protect itself from heat as you'll need to route the cord near the exhaust manifold.
Here's the catch, according to the dealer, Toyota never sold a block heater for the 3.4L 5VZ-FE here in the states.. the dealer ordered them from another dealer in Canada because they are only sold in Canada.
I cannot figure out the manufacturer of the heater (as I prefer to order straight from the source). On the heater is casted LR20976. This crosses over to Hotstart heaters, but this number is no where in their catalog. Thru other websites, the Toyota part number is listed as PYR02134 which comes up as Pyroil Canada, but I cannot find a website or any information about them.
If anyone can help figure out the manufacturer and where else to buy, I'm sure others would appreciate this bit of info.

These work great and super easy to install. Very durable...just use a lot of silicone and make sure the pan is totally bare metal. They even have a sale and free shipping now.

Made in Canada! I'm surprised they don't sell them in the states though, There are plenty of states that see block heater weather. Weird.
As far as I know, you can only get Toyota parts from Toyota. The manufacturer probably doesn't sell to the public. I've worked in plenty of auto parts plants, and the product is typically not available otherwise.
I meant to add the stamping of the part for reference..

[MENTION=149505]hagnecco[/MENTION] thanks for all the info! I'm gonna cross reference the Toyota part number when I get to work today and see if I can pull any more info on it and if there are other options besides the Kats one.
I'm not doubting they work, but my 2 cents are that they only warm the oil sitting on the bottom of the pan. Coolant heaters heat the coolant and when heat rises there is some form of self circulation heating the entire block. Just my opinion. Working with diesels I see a lot of pros and cons with heating systems.

I understand your thoughts, but they absolutely do heat the block adequately. How do I know...I use them and have checked temps before and after. I also have and use coolant block, coolant tank, internal and pad heaters on diesel 20-425hp tractors, and diesel PU-Class 8's. We don't have bitter cold Temps but we go sub zero a couple weeks a year. (3cyNot arguing there may be some that work a little better but nothing easier to install. Get the 250 that fits your oil pan (measure possible fitment before ordering) and you will be happy with it. I run mine on timers...and if its 0 out it takes 7-9hrs to hit max temp. These timers are the best I have ever found.

Let me ask you this then... Have you used and what are your thoughts on the the silicone heating pads for batteries? Are they effective in their purpose of keeping the battery warm on frigid days? Do they melt plastic trays? I'd like to hear some input on these? I'd like to try one on the 4Runner before I buy 2 of them for my diesel.

No I have not used them. Call the company and they will let you know. I have used a electric heater blowing on them or in the battery box, and heating pads wrapped around batteries. Don't think either of those work any better than a trickle charger in my experience.

They can be too effective if you get the wrong one. They make a low wattage larger area one meant to go under a battery. Will warm the battery not cook it. If you stick a 200 watt oil pan heater under your battery things are likely to burn. Make sure you get the right one.
The wrap around battery blanket is 45 or 50 watts and they work just fine. Just a bit of a pain to put on. I have had one for 20 years on various cars. The battery doesn't need to be hot, just warmer.
Oh, and a note from experience. You will be better off with the Toyota block heater. The cheaper ones are false economy. It's cheaper to buy but they need replacing more frequently and who wants to deal with that? You can see the difference in quality.

When you installed the toyota brand heater, what position did the heating element face? straight down?
I am having trouble getting my toyota brand heater in place. With it facing the 6oclock position, the top half didn't seat properly and popped part of the o ring out and caused a leak.
Any recommendations to get er to fit right?

I’m gonna be taking mine out this weekend since it’s leaking. I live in SoCal so I don’t need it. How does it go in? Screwed in or does it hold with just pressure?

Someone posted an install guide for a 99 and I see you have a 97, any idea if this would be the same on on 01? Many thanks! This is super helpful btw I was going to get the Kats version.
Also N00b question, how can I save a thread...

It’s the same for all of them. I’ve installed one on a 01, 99, and 98
At the top, there's a tab for "thread tools" pick that, and then 'subscribe to thread' After you do that you can see your subscribed threads in the UserCP. I think there is also an email notification option IIRC
