Specs & function: G8MS-1A41T-R automotive power relay, 12VDC coil, 1 Form A (SPST-NO), rated load 12VDC 20A (inrush up to 100A), coil resistance 100 ohm (+/-10%), service voltage range 10-15VDC; built-in coil suppression resistor; sealed/waterproof case for harsh under-hood environments. OE: G8MS-1A41T-R.
Install tips: disconnect the battery before service; pull the old relay straight up (avoid prying the socket); match the terminal layout/markings on the relay body with your relay base before insertion; press fully until seated; if the circuit is high-current (cooling fan/glow plug/air pump/resistive load), inspect the relay socket and related fuse for heat damage or looseness and replace any burnt terminals. Common location is inside a vehicle fuse/relay box or junction block - confirm by vehicle manual/diagram.
Fitment check (no guessing): confirm fitment by OE/relay marking "G8MS-1A41T-R" + coil voltage (12V) + terminal layout, and verify the controlled circuit in your vehicle manual (examples of relay-controlled loads: engine cooling fan, glow plug, air pump, resistive load). Do NOT rely on look-alike relays-different pinouts/ratings can cause no-start, fan not running, or blown fuses.
When to replace: intermittent no-click, relay chatter, cooling fan not coming on, defogger/heater circuit not energizing, hard start due to control relay drop-out, or recurring fuse blows in the related circuit. Replacement may help if the relay tests out of spec or shows heat discoloration; diagnose the root cause (shorts, seized fan motor, weak battery/charging issues) to prevent repeat failures.
Related parts for a more reliable repair: consider replacing a worn relay socket/terminal kit if the base is loose or heat-damaged; keep a spare relay of the same OE marking for the same relay box position; if multiple relays share the same fuse/relay box, label positions during removal to avoid mix-ups. Always confirm by OE number and the vehicle's relay diagram.
وصف
This listing is for a replacement relay identified by OE/relay marking G8MS-1A41T-R. Please confirm fitment by OE number/marking and your vehicle's relay diagram before ordering.
Coil voltage: 12VDC
Contact form: 1 Form A (SPST-NO)
Rated load: 12VDC 20A (high inrush circuits may draw higher current)
Coil resistance: 100 ohm (+/-10%)
Service voltage range: 10-15VDC
Protective construction: sealed/waterproof case; built-in coil suppression resistor
Engine cooling fan relay circuits
Glow plug / heater relay control circuits
Air pump or other high-current resistive loads
No click / intermittent operation
Fan not running or relay chatter
Intermittent power delivery to the controlled circuit
Repeated fuse issues in the same circuit (check for shorts or motor problems)
Disconnect the battery, match the terminal layout/markings on the relay body to your relay base, and press fully until seated. If the socket shows heat damage or looseness, repair the terminals/switch block as needed to avoid repeat failures.
Fitment reminder: Do not guess by appearance. Confirm fitment by OE/relay marking G8MS-1A41T-R, coil voltage (12V), and the vehicle relay diagram/service manual.
