Fusebox Relay Contacts - 82998-12060 Fusebox Blade Fuse Contacts - 82998-12140 I did this 15+ years ago. It's pretty easy to figure out, but it's a pita to do.

I fixed the 3FE EFI relay issue by replacing the terminals with OEM terminals using high temp wire all the way out to connector EB1. Did the EFI fuse contacts as well while I was there. It's been solid for the last 15 years.

Well worth the effort.

I've been running 20k oil for years without issue.

Here are some pictures for your amusement: Both fans are sitting on blue hubs. There is a significant difference in blade protrusion between the old and new fans. I think after 30 years of sucking 200 degree air, the fan doesn't really owe me...

The Toyota EWD tells you how to remove all the different types of terminals on the vehicle. It is free to download from the resources section. The crusty wire is the load side of the EFI relay (pin 4). Again, the issue is not the relay.

Yep. I cleaned and inspected the old fan. Not going back on the truck. I'll wait for the new one.

Yea, I assumed that's what you meant. I was able to gain just a bit with the side brackets. I considered drilling out the holes, but opted to leave it be. Frame looks pretty solid from multiple angles. Radiator is in along with the new water...

Terminals remove from the bottom. Yes, it's a PITA to do. You don't have to remove the terminals to compress the female contacts unless they are damaged.

I'm also thinking that after 30 years, a new fan isn't the worst idea. I'm still waiting on delivery, but I want to compare blade angle and protrusion between the old one and new. In the interim, I'm going to start putting things back together...

I've been through 4 radiators over 4 years with two being from fan strikes. The TYC1918 is a thick radiator with superior performance but doesn't like fan tickles. This particular fan strike was from normal driving and the resulting leak was...

I’ve had 2 such slices with a 2row Denso radiator. The problem was 2 fold. First the bottom radiator mount is a little sloppy and I was able to slide it forward to create a larger gap. There is a new design for the fan shroud that eliminates...

That is the EFI main relay. There are many threads regarding this. It is a common issue on the 3FE equipped trucks. Your contacts appear to be arcing due to poor contact. I would try to tighten up the female contacts if they are not damaged...

You need spark, fuel, and air. Each one will lead down a different path.

LOL. I haven't touched that site since 2009. http://www.sdsysdesign.com/TLC/

First of all, if the coil was faulty, there would be no spark. I'm going to say your distributor, igniter, and ignition coil are fine. Most "budget friendly" meters are not very accurate when reading low resistances. You're reading across a...

No, not really. But I am getting pretty good at swapping radiators.

The rad I just pulled out was installed last April with all new OEM everything. That one was eroded at the very top by a hanging wire harness that had broken free and was chafing for quite a while.

I am in the process of replacing an OEM TRAD 16400-66040 in my LX450. I was on a not so extreme trail and the fan sliced the radiator at the very bottom, a fraction above the seam for the lower tank. I'm still trying to figure out how this...

IMO the OEM fiberglass battery trays are a weak point in an otherwise robust vehicle. Tabs break easily and the OEM tiedowns tear through the fiberglass. I bought a new one and modified it with epoxy and thin sheet steel where the tiedown hooks...

I'm here to help...or patronize and annoy.

We weren't on a particularly difficult trail. Upper or lower anthracite. I can't remember the name. The trail with the rocks and trees :) It was difficult getting pulled by Mark's 40 and trying to steer the LX450 with no power steering or power...
