NOTE: Do not replace the thermostat for a ­collapsed radiator hose.

Toyota Direct Injection? Port Injection? Why Not Both?

Port fuel injection and direct fuel injection systems each have their advantages and disadvantages.

If you’ve serviced import vehicles for at least the past decade, you may have seen a Toyota vehicle that has both direct fuel injection and port fuel injection. You will see port fuel injectors in the intake manifold and a direct injection fuel pump. Toyota calls this system the D-4S or Dynamic Force Engine (the “S” stands for superior) and the earliest application was on the Lexus GS SUV with the V8. The D-4S system is not a “cold start” or “dousing” injector system, like that on V6 engines from the early to late 2000s.
