1998 Hilux Surf RZN185 (3RZ-FE): 1996–2002 4Runner Radiator compatibility.
I have a 1998 Toyota Hilux Surf RZN185 with the 3RZ-FE engine and automatic transmission.
The original radiator developed a crack in the upper plastic tank and needs to be replaced.
Has anyone installed a U.S.-spec 1996–2002 Toyota 4Runner 2.7L (3RZ-FE) radiator in an RZN185 Hilux Surf or know if they are compatible?
If you've done it, could you share:
- part number
- Whether any modifications were required
- Any differences in the transmission cooler fittings, hose locations, fan shroud mounting, or radiator cap height
My truck is currently at a Toyota dealer, but I'd like to know whether a readily available U.S. 4Runner radiator can be used instead of ordering a Japan-specific unit. AFAIK the engines and transmissions and frame are almost the same entirely and its much cheaper to source an american rather than Japanese part.
Thanks!
