1985–1989 Isuzu I-Mark wiper FAQ
Quick answers about this car.
What size wipers fit a 1985–1989 Isuzu I-Mark?
The 1985–1989 Isuzu I-Mark takes 18" driver-side and 18" passenger-side wiper blades. The arm uses a Bayonet connector.
Do all 1985–1989 Isuzu I-Mark model years use the same wipers?
Yes. Every Isuzu I-Mark from 1985 to 1989 shares the same blade lengths and arm type. If a blade fits one of these years, it fits them all.
What connector does the Isuzu I-Mark wiper arm use?
Bayonet. Most replacement blades include an adapter for it, so check the adapter chart in the package.
Can I use a wiper blade one size longer or shorter?
Stick with the listed sizes. A longer blade can hit the windshield frame or the other blade, while a shorter one leaves an unwiped gap. If your old blades don’t match our sizes, measure them end to end.
How often should I replace my wiper blades?
Most drivers change them every 6 to 12 months. Swap them sooner if they start to streak, chatter, or miss spots.
