Parts for your 1987 Suzuki Swift-Egr valve

1987 Suzuki Swift EGR valve — fitted or not?

Based on technical references for the Australian and New Zealand market, the 1987 Suzuki Swift (AA/SA series, commonly with the G10 1.0‑litre and G13A 1.3‑litre carburetted engines) was generally not fitted with an Exhaust Gas Recirculation (EGR) valve from new. Factory literature for the mid‑1980s Swift/Cultus platform in AU/NZ editions describes PCV, evaporative canister, catalytic converter and ignition/fuel tuning as the core emissions systems, while EGR appears only in North American–specific sections. Gregory’s/Max Ellery–style workshop manuals for the era note EGR on some export markets, not for Australia or New Zealand. Period Suzuki parts microfiche/EPC listings for AU/NZ models likewise don’t show an EGR valve assembly, whereas US/California listings do. This aligns with ADR 37/00 (Emission Control for Light Vehicles), which set tailpipe limits but did not mandate EGR, manufacturers could meet NOx with alternative strategies.

Why EGR wasn’t used on AU/NZ 1987 Swifts comes down to the emissions recipe Suzuki chose for those small-displacement, lean‑burn carb engines. With a catalytic converter, precise ignition timing, vacuum/thermal controls, and conservative cam timing, the Swift could meet local NOx targets without adding the complexity and cost of EGR hardware and its hot crossover plumbing. The result was a simpler intake manifold and fewer vacuum circuits on AU/NZ cars compared with North American counterparts.

There are a couple of caveats owners should keep in mind. Some grey‑import Swifts/Cultus models and engine swaps may carry EGR equipment, these are typically Japanese‑domestic or North American spec. A quick visual check will tell the story: an EGR system has a small, saucer‑shaped valve on or near the intake manifold, a steel tube running from the exhaust manifold to that valve, and vacuum hoses leading to thermal/vacuum switches. If none of that gear is present, it’s almost certainly an AU/NZ‑delivered car without EGR.

For servicing an AU/NZ 1987 Swift, the practical focus is on the emissions kit it does have. Check the PCV valve for free movement, renew brittle vacuum hoses, verify base ignition timing, keep the carburettor mixture and idle sorted, and ensure the charcoal canister and purge lines aren’t blocked. A healthy cooling system also keeps combustion temperatures in check, helping NOx without the need for EGR. If a grey‑import car with EGR lands in the driveway, it’s worth inspecting the EGR passage for carbon build‑up, testing the diaphragm with a hand vacuum pump, and replacing any leaking gaskets to prevent rough idle or pinging under load.

• Key references consulted: Suzuki factory workshop material for AU/NZ SA/AA Swift (mid‑1980s editions), period Suzuki EPC/microfiche for AU/NZ models, Gregory’s‑style Swift manuals (1980s–early 1990s coverage), and ADR 37/00 framework indicating EGR is optional as a compliance method.

Popular questions

Did the 1987 Suzuki Swift sold new in Australia or New Zealand have an EGR valve?
For AU/NZ-delivered cars, no. Factory manuals and AU/NZ parts catalogues list PCV, evaporative control and a catalytic converter, but no EGR valve on the common G10/G13A engines. EGR appears on North American versions to meet stricter NOx limits.

How can someone confirm if their 1987 Swift actually has EGR?
Look for a small, round, vacuum‑operated valve mounted on or beside the intake manifold with a metal tube feeding it from the exhaust manifold. If that gear isn’t there and the vacuum diagram under the bonnet doesn’t show an EGR circuit, it’s not equipped. If it’s a grey import, it may have EGR despite the year.

What should be serviced instead if there’s no EGR on an AU/NZ 1987 Swift?
Prioritise PCV operation, vacuum hoses, carburettor tune, ignition timing and the charcoal canister. Keeping the cooling system in good nick and the catalytic converter unobstructed also helps maintain clean running without EGR.
