Parts for your 1998 Nissan Pulsar-Radiator hose

1998 Nissan Pulsar radiator hose — what it does and how to look after it

Yes, a radiator hose is absolutely used on the 1998 Nissan Pulsar (N15). Technical references including the Nissan N15 Pulsar Factory Service Manual (Cooling System section), Gregory’s Service and Repair Manual for Pulsar 1995–2000, and Australian hose catalogues from Gates and Dayco all list upper and lower radiator hoses for GA16DE and SR20DE engines. That settles it — this model relies on radiator hoses as part of its liquid-cooling system.

On the N15, the upper hose carries hot coolant from the engine to the radiator, and the lower hose returns cooled fluid back to the water pump and thermostat housing. If a hose lets go, it can dump coolant fast and send the temp gauge skyward — not ideal for an engine that likes a steady operating temperature.

As part of servicing your 1998‑Nissan‑Pulsar radiator-hose, a quick look under the bonnet goes a long way. Check both hoses when the engine is cold:
