First officer reported two EICAS messages on final; causing a go around to allow time to run the QRH...

Narrative:

ZZZ: departed from runway xxl. On the approach into ZZZ1 rnp X runway xx; PF (pilot flying) called for gear down; flaps 20. Immediately pm (pilot monitoring) extended the gear lever there was a warning horn and right body gear disagreed alert followed by an EICAS message 'equipment cooling'; the second time message showed up during the flight. At 1;000 feet both pilots called for 'go around'. PF requested for vector from ATC for an immediate landing ILS runway xx. Pm worked the QRH read the gear disagreed checklist. Equipment cooling non-normal checklist was completed earlier during cruise. The message went away both times. Please note there are lots of write ups on a/C X. (Le flaps; outflow valve; thrust reverser; west&B indication system; cockpit smoke vision; equipment cooling; ATC failure & landing gear config warning.). These were all the numerous write ups on the aircraft from our flight and previous flights. I suggested the aircraft should be aog with immediate effect and the above listed malfunctions should be rectified prior to the aircraft being released for operations. This is a classic example of chains of error; that should be broken before leading to an incident or accident. Thank you.

Title: First Officer reported two EICAS messages on final; causing a go around to allow time to run the QRH; landing safely on next approach.

Narrative: ZZZ: Departed from runway XXL. On the approach into ZZZ1 RNP X RWY XX; PF (Pilot Flying) called for gear down; flaps 20. Immediately PM (Pilot Monitoring) extended the gear lever there was a warning horn and right body gear disagreed alert followed by an EICAS message 'Equipment Cooling'; the second time message showed up during the flight. At 1;000 feet both pilots called for 'Go Around'. PF requested for vector from ATC for an immediate landing ILS runway XX. PM worked the QRH read the gear disagreed checklist. Equipment Cooling non-normal checklist was completed earlier during cruise. The message went away both times. Please note there are lots of write ups on A/C X. (LE Flaps; Outflow Valve; Thrust Reverser; W&B Indication System; Cockpit Smoke Vision; Equipment Cooling; ATC failure & Landing Gear Config warning.). These were all the numerous write ups on the aircraft from our flight and previous flights. I suggested the Aircraft should be AOG with immediate effect and the above listed malfunctions should be rectified prior to the aircraft being released for operations. This is a classic example of chains of error; that should be broken before leading to an incident or accident. Thank you.
