PartFinder earns a commission on some outbound links. It never changes what you pay, and it never changes how results are ranked. Offers are ordered by how confident we are that the part fits, then by how well they match, then by whether they ship from your own country, and last by total landed cost.

Link out without affiliate tracking where available, on this device.

Fitment information is a best effort, not a guarantee. Always check part numbers against your own vehicle before buying, especially for imports and cross-market matches.

We'd like to use Google Analytics to see which pages people find useful. It sets cookies, so it's off unless you say yes. The site works exactly the same either way. How we handle data

Thermostat for a 1989 Lexus LS400 · PartFinder

How sure are we these fit?

Confirmed fit: The seller's own fitment data lists your exact vehicle. This is the strongest signal available.
Fits a twin: Listed for a vehicle that is the same car under a different badge, or shares its platform. Often the only stock available for an import, but verify before buying.
