- 95270-3A005 Relay Assembly-Heater for automotive heater/preheater circuits; typical 12V DC coil, 4-pin plug-in blade terminal relay (common 4-terminal layout often labeled 30/87/85/86—verify on your original). Superseded/Replaced by OE# 36860-42300-DS / 3686042300DS. Commonly used for diesel heater-related circuits (for example: PTC heater / glow plug / fuel filter heater) depending on vehicle—match by fuse/relay box label and OE#. Sealed housing and tight-fit terminals help reduce intermittent power loss caused by a weak, sticking, or heat-damaged relay.
- Install/replace: disconnect the negative battery cable, then locate the relay in the engine-compartment fuse/relay box (diesel heater/preheater relays are often listed on the fuse box cover or owner’s manual). Pull the old relay straight up, inspect the socket for heat or corrosion, and press the new relay in fully—do not force it into the wrong cavity. Important: confirm OE# 95270-3A005 (or the superseded OE# 36860-42300-DS) and match the pin layout/terminal markings before reconnecting power.
- Compatible with 2010 Hyundai i30 Engine Compartment (Diesel Box) Relay; Compatible with 2007 Kia Rio Engine Compartment (Diesel Box) Relay; Compatible with 2007-2012 Kia Cee'd SW (ED) Engine Bay (Preheater Control Circuit) Relay. If not listed, confirm fitment by OE# 95270-3A005 (or superseded OE# 36860-42300-DS) and the relay map on the fuse box cover/vehicle manual.
- Troubleshooting help: a weak heater/preheater relay may cause intermittent preheat operation, hard cold starts (diesel), or no-power symptoms in the related circuit. Diagnose before replacing—verify that the relay clicks and switches when energized, and check the socket for heat damage. When servicing the same circuit, it’s common to inspect related items like glow plugs, the preheat/control module, and the fuses/links listed on the fuse box cover or in the vehicle manual.
