Suzuki Reservoir Cap

[Kentroyals5]

I have a 2010 Suzuki Kizashi and noticed the other day when changing the battery that the coolant reservoir cap was missing. Is there any short term fix as none of the local AutoZone/OReilly's, etc had any sort of reservoir cap that fit. I reached out to local (WA state) Suzuki service places, even reached out to Canadian Suzuki service places and no one has this part (17932-76M10). It's on back order, like 3 months out.

Does anyone have any access/extra reservoir cap?

Is there any remedy I can use to cover the current reservoir cap (get a cap and tape it down?) so I can use for my short 3 mile trips back and forth to the office? Seems insane a $30 cap could render my car useless for 3 months.

Thanks!

I got your email and sent you a PM but I'll reiterate the message here too:

Some have claimed a twist cap from a windshield washer jug or coolant jug will fit and twist onto the reservoir. Try that as a cheap, quick fix.

As for rendering the car useless, it's not true. The Kizashi's reservoir is not pressurized and more acts like an overflow reservoir. The cap that really matters, and holds the critical pressure, is the radiator cap, not the reservoir cap. When I lost my reservoir cap, I drove for well over a week or two without a cap. It's not critical and is part of why it doesn't hold much pressure and is easy to lose in a boil-over.

Don't stress about it and try a jug cap.

Thanks for the response here. Any recommendation on coolant to purchse (and I'll see if cap works)? There isn't any coolant in the reservoir, so I presume I need to fill that towards the max line?

Use Long-life Blue coolant. It's quite common for Asian cars these days other than Toyotas. You can find pre-mixed jugs at any auto parts store.
Fill somewhere between min and max. Drive for a few days and then check level again as the cooling system will draw from that reservoir if needed.

I could only locate Zerez Asian Vehicle 50/50 as only blue coolant nearby (1 mile). Pentofrost A3 was like 30 miles away...was nervous about making that drive. Should I order that Pentofrost and wait a few days?

Thank you!

I don't think it really matters. Use the blue coolant you can get most easily. In fact, I think I last topped off with Zerex. I've also used Pentofrost before.
Again, don't be nervous about not having that reservoir cap. It's almost inconsequential and it's possible you discovered that lost cap long after actually losing it, meaning you were unknowingly driving without it for a while.

Hey I don't know if this is helpful but from what I've seen this part might work on the kizashi not hundred percent sure but I will be trying this out in the coming week as I also lost my cap and for now am using the cap of a coolant container and it work well but when doing heavy acceleration and rpm upwards of 4000 sometimes the collant spills out and the smell is not good.will update you by end of the week
