Default Radiator Neck Adapter Doesn't Fit (Off-Camry)

I have a 1996 Tercel that Amazon says Stant adapter 12025 fits on the radiator neck such that I can pressure test the cooling system.

The adapter does not fit my radiator, but the corresponding 12024 fits the radiator cap perfectly. Specifically, the 12025 fits on the pressure tester, and sits, but does not thread tightly, on the radiator neck.

I have the appropriate radiator cap and radiator neck adapters for my 1989 Camry (#12021 and 12027), and I know how to set up the adapters and pressure test

Any thoughts as to what's wrong?

Did the unit come with multiple o-rings to add/remove to get the right fit?

Thanks.

No. It was only solid piece of metal:

That's the same shape, without adapters, that fits perfectly on my 1989 Camry's radiator neck.

Do you think that this kit will work (chrome object being the o-ring you're referring to)?

Does the "solid" unit have an internal spring to compensate for clearance differences and allow a tight seal?

If no spring, the addition/removal of rubber washers adjusts the seal.

Read the customer comments about this product at your first Amazon link.

Thanks.

The adapter is without springs and did not move.

I understood everything in that review except: "...This new type you have to remove rubber washers one at a time until it fits the radiator without leaking..."

By "rubber washers," do they mean in the center of the adapter?

However, that same side that connects to the radiator neck has two notches without tapering on the notches or the other areas on that side.

This is the silver version of the black version that I have:

Finally, would this kit work, or is it missing the radiator neck adapter?

The adapter you have appears to be for 35 x 10 mm deep cap. There is another adapter for a 35 x 16 mm deep cap.

See link:

Amazon Amazon

Thanks. I now understand that #12025 is 35 x 10mm and that's why it won't fit.

I don't see the adapter that is 35mm ID and 16mm deep. What's the part number?

Read the info at the Stant site link:

http://www.stant.com/files/3514/0979...r_Adapters.pdf

The 12024/12025 adapters are for a 31 mm x 10 mm cap/cooling system as used by Tercel.

The Camry cap/cooling system is 16 mm x 35 mm.

The 12021 adapter is stated to be for a 16 mm x 35 mm cap. The 12027 for the cooling system.
