KZJ78 Radiator replacement?

[kgrove]

Follow up - that Daiwa radiator is a true drop in replacement for the OEM radiator. You'd have to check if it comes in a MT flavor as well. It came with a bung plug and the AT hose connectors, but no cap. The fan shroud mount were close to perfect - they were slightly mis-aligned if you pressed the bottom tabs all the way down, but lift up a couple mm and the holes lined up perfectly. The height and width were identical to the OEM, so the bracket mount holes were on target and the radiator mounted in position perfectly. I forgot to measure the core thickness, but it felt the same, so I'm assuming it has the same coolant capacity.

Here's a photo of the old and new radiators side by side (the old one still has the mounting brackets attached) as well as the new one in position. I've still got some work to do before I can fill and test it. I'm replacing every cooling hose on the car plus while those are off, tending to a few other things. Of course the real test of the radiator only comes in 10 yrs if it's still humming along good.

@kgrove did you end up ordering it from Daiwa USA or did you go through a Japanese source?

The Japanese source in the link posted earlier. I never tried reaching out to Daiwa USA... probably would have been smart to check if there's a US source with lower shipping costs. The actual part cost from ftontline (Japan source) wasn't that bad at around $400, but the shipping cost was something like $275.

I need a favor... can somebody with a KZJ78, especially one with the rear heater, take a couple photos that show detail of how all the small heater hoses near the fire wall connect up?

I took all my hoses off in part to replace them but to also do an EGR delete while I was back there. I had all the old hoses arranged on the garage floor in a way that made sense to me so that I could piece together the replacements in the right order. Unfortunately, somebody decided they needed some floor space in the garage and threw all the old hoses in a box so I've lost my comparison points. I usually take good photos of the "before" just for this kind of screw up, but for some reason this time I didn't. I think I've got it from the parts diagrams, but it's not perfect as the tubing is spread over a couple different diagrams without a crystal clear layout of the whole package.

KZJ 78 with rear heat, let me know if you need another angle. Corrugated loom is aftermarket gauge wiring protection.

Thanks much. These confirm what I thought based on trying to see which puzzle pieces seems to fit, but it's helpful to have visual confirmation. I needed to cut a couple of the hoses to remove them and I wasn't positive I was matching the right halves together in trying to re-create the original shapes.
