Several issues on the s5, even more on the s4.

Lets first start off with the s5 GTU.

The hatch is stuck closed, I do not have the key for it, and the latch that pops it in the cabin only gets the left side popped. Is there something for the right side that I could quickly fix to get it open? Has anyone else run across this exact issue?

Next, my car: '88 SE.

1) I'm swapping in a s5 na into the body, and I got a s4 koyo radiator. People say it should still work, but doesn't the s5 have different hoses and different locations for stuff? Just wondering if that can be confirmed that a s4 koyo radiator will work for an s5 na.

2) The gas tank lid won't close, period. The rear quarter does have damage, but I always used to have to pry it open, now I am having the opposite reaction... it never will stay latched. Any clever ways to (without ruining anything) keep it closed, and just have it to where I need to pry it open again with my key?

That is it for now, but I know there are a few other things that need to get fixed on it as well. Just hoping to get some new insights that someone else may think of.

Take the plastics off your hatch latches, and look around on each one for a little tab that will move side to side. If you move it over, it will unlatch the hatch. It just sucks that you are going to have to crawl back there from the passenger seat to get at it. As for the rest of it, I have no clue.

There's a tab that keeps the gas lid 'locked', you've probably bent it so that it no longer grabs.

I'll leave the rad issue to a better suited person. Although I will mention that I've got a stock s5 rad that I can trade you for your s4 koyo lol

The S4 and S5 radiators differ only in minor detail...mainly, the location of the filler port.
This is only an issue- and a minor one at that- if you use the stock airbox/intake snorkel.
The main hose bungs are identically positioned and sized.
