today at work I was looking at getting a rad cap for our 90T and it's different than say a 88. Called up the local dealer and they said the rad caps are different. 86-89? and 90-93 they said. What is the difference between the 2? I looked up radiators for mk3's and they all call for the same part # radiator which doesn't make sense. Our 90T has a aftermarket radiator. So does it really matter which one I go with? both are 13PSI caps. 1 is made in USA and is more conventional looking... other is made in S.Korea and is more Jap OEM looking.
2 different radiator caps for mk3???

Its possible that the 'depth' of the sealing part of the caps are different.
my '89, and all others that I've seen use a cap that fits a 'deep' neck. There are radiators that have a 'shallow' neck, and thus need a different cap for it.
I've had cars in the shop that had the shallow neck aftermarket radiator instead of the factory deep neck one.
Many Honda's have shallow necks.

so in other words I gotta fit the cap to my aftermarket radiator. So I'll take both out in the parking lot and fit them up.
The 90+ caps are smaller (lower profile). I bought an aftermarket rad for my 90T and couldn't figure out why the original cap didn't fit. Turned out that the aftermarket was designed for the 'old' style larger cap.
Nice. Ok, so i'll pick up a older style cap than. Thanks for the heads up. Well that would explain why my overflow is filling up. the original cap doesn't work with the aftermarket radiator. I thought the cap was just wore out.
turbomk3- what cap did you end up using? a early style mk3 cap? I picked up a early mk3 style cap today at work. I'm gonna fill the Radiator up and get the overflow down to proper level and see how it does.
