Is there any trick to remove the rear radiator cap on the 84 2.5 duke? Please forgive me if this is a silly question.

Does your Fiero have a rear radiator?

The cap on the thermostat housing can sometimes be difficult to remove. In theory you just push down (to clear the lock tabs) and turn the cap counter-clockwise.

I've had to use a large pipe wrench on ones that hadn't been removed for years. You need to be careful though as you don't want to distort the face on the housing or bend the tabs on it.

I've used either a big pair of channel locks or a strap wrench on mine. Those caps do get tight.

I use the small oil filter wrench that I use for removing the Fiero oil filter. Perfect fit. Not the cup style, but the kind with a handle. The V6 hose clamp is situated such that it's like a scalpel and will slice a hand open as handily. Just put the clamp around the cap, turn it with one hand and press down with the other. It doesn't scar up the cap like a pipe wrench or large channel locks.

You may have to buy a new cap, if this one was stuck on pretty hard.

Thanks everybody. I will try your ideas and see what I come up with.

I love this forum. Everyone is usually so very helpful. When I ask a simple question on the Audi forums, everyone goes out of their way to try and make me (and others) out to be stupid. Then they get all defensive when you call them out.

Tap it with a screwdriver around the edge like you would tap a tight pickle jar lid with a spoon. It should break the seal. If you find pickles, time to flush the radiator.

Replace it with a new one, I put a thin wipe of grease on the new seal to help remove it next time. I also cleaned up the top of the housing for a good seal.

That shouldn't be necessary with a new cap. I'm not sure about all brands, but it appears that the seal on the old (AC?) caps was firmly attached to the cap. In other words, when you turned the cap the rubber seal had no choice but to twist on the face of the thermostat housing. We all know how difficult it is to remove one of those damn caps if it's been on there for a long time. However, the seal on the new style caps spins independently from the cap. This makes it a helluva lot easier to remove one of these caps, as even if the rubber seal has bonded to the thermostat housing, the cap itself will still turn and release.

I second the utility of channel locks for this purpose. I ended up buying a larger set of them on a road trip where I had some trouble with possible overheating issues. It turned out to be a bad sensor but I had the cap on and off at least five times.

I have done the same for the 2.5 I had and also for the 3800. Big channel locks work nice.
