Radiator removal

[S B C]

Advice please.
I've got a crack in my GTO3 radiator.
I've started to remove it and notice that there are 3 rads there. I assume that the thin one attached to the water rad is the air con rad ? The water rad and the air con rad look to be welded to the same bracket.

There is also a very small one. Is that an oil cooler?

I also notice that some of the mounting bolts seem to be awkward to get at - particularly the ones at the bottom. Does the floor need to come off to get at these, or is there an easier way?

Thanks

Chris.

small rad is power steering fluid cooler.

Changed mine a few years back.
The aircon rad and water rad should seperate. I'm sure they're just bolted to the same bracket.

Didn't remove the floor- but obviously remove the clam to give you room to work.
You also shouldn't need to undo any pipes from the aircon or steering.

I remember it being a bit tight getting the rad out once unbolted.

While you have it all apart it's an ideal time to do the tunnel cooling mod if you want it. I didn't notice much difference inside, but it must be keeping the rear turbo a bit cooler.

Finally there are some reports of getting the system to bleed. I just ran mine with the small bypass/overflow on top of the rad open until coolant came out. Might have done it with the front raised slightly to ensure that outlet was the highest point in the system.

Spot on , just make sure you get the latest rad with the flexible mounts as they prevent the rads splitting which is the main problem .Jetstream stock them ,despite the front rad ,rear engine they bleed quite easily [compared to a 911]
