This Koyorad radiator drops straight into Toyota Land Cruiser 100 Series FZJ105 and HZJ105 models from 1998 to 2004 with a core standing 425 mm high and 695 mm wide. This setup keeps coolant moving across a 36 mm thick core when you tow or crawl in low range. This unit lines up with 38 mm inlet and 42 mm outlet hose diameters so you keep standard plumbing and factory clamps. This gear also runs an internal transmission cooler with a 375 mm length to help the auto stay within its operating window on long climbs. This size gives enough contact area for fluid without needing extra space under the bonnet. This radiator suits petrol and diesel engines that work in high ambient temps on outback tracks. This is a smart buy if you want known dimensions and straightforward fitment on a 100 Series tourer.

Q: Does this radiator suit both petrol and diesel 100 Series models?

Yes, it suits FZJ105 petrol and HZJ105 diesel Land Cruiser 100 Series with automatic transmissions from 1998 to 2004. That means one part number will cover most Australian delivered 100 Series wagons in those variants. Always confirm your build code and transmission type against the vehicle compliance plate. A quick visual check of mounting points and hose positions before install is also worthwhile.

Q: Is a separate transmission cooler required with this radiator?

This radiator includes an internal transmission cooler that measures 375 mm in length. Many touring setups will run solely on this integrated cooler. Some owners still add an external cooler for heavy towing or hotter regions. The integrated cooler remains connected to stabilise warm up times and baseline temperatures.

Q: Do the hose sizes match the original Toyota hoses?

The inlet measures 38 mm and the outlet measures 42 mm which aligns with common 100 Series automatic hose sizing. This helps the radiator slot into existing plumbing without stepped adapters. Always inspect your old hoses for hardness or cracking during the swap. Replacing tired hoses at the same time can prevent future leaks.

Q: What should I check before ordering for my Land Cruiser?

You should confirm your vehicle is a 100 Series FZJ105 or HZJ105 built between 1998 and 2004 with an automatic gearbox. You should also compare your current radiator core height of around 425 mm and width of roughly 695 mm. Checking the position of the transmission cooler line fittings will help confirm match. A quick comparison of mounting tabs and shroud points can avoid surprises on install.
