Hi All,

My R33 has a leak from the heater core located under the dash on the passenger side. Noticed the leak while I had the Air-con on and a smell of coolant inside the cabin.

Does anyone have any experience in removing the heater core. Basically I want to know does the whole dash need to be removed or is it sufficient to remove the glove box section to work on the heater core.

Any advice is appreciated.

Paul.

Whole dash has to come out, allow 2-4 hours to do it.

There is a detailed guide on how to do it on here by predator i think... have a search... follow that guide. Here are his photos he refers too (the photos died from the posts ages ago): http://gtr.ferni.net/misc/dash_removal/

I've done it a couple of times. Go buy a brand new natrad heater core from your local natrad dealer, cost you <$200. Good luck :)

Out of curiosity, how did you notice the coolant leaking? Did the passenger side footwell fill up with coolant, or did it run under the carpet?

I could smell the coolant first, then I saw the passenger floor mat wet with coolant. As I investigated further I also noticed coolant was going under the carpet.

Thanks for the advice and photos, job doesn't look easy so I am not looking forward to it!!

Its not as hard as it looks, lots of wires make it look scarey but hardest part is remembering which bolts go back where. If you really cant remember, grab a bunch of envolopes and label them with the bolts in so you know where they go back ;)

ive got same problem.. ive started undoing the bits and pieces from the 32.. but have a feeling its gonna be sitting there for quite a while longer -_-

i thought it coulda been the pipes leaking but from the pics just seems like probbably leaking from core wihch will again cost abit to purchase another one. doh

good luck dude

    • My hold point for future mods is that I want a OEM detachable hard top first, but, finding one is a pain, MX5 Mania are looking for one for me, but, as hens teeth are more common, finding one in Australia is proving problematic  I can get a OEM one from overseas, hell, you can still get new ones in 'Merica, but, shipping is a absolute killer and I cannot justify the cost, or the risk of it being damaged during transport As for the aftermarket hardtops, whilst they do the job of being a hard top, and are fine for a track car, they don't seal well (read: leak like a sieve in the rain), and you need a plastic/poly rear window, plus they are a bolt in option only and not made to be easily removed I liked how the hard top on my NB could be fitted, and removed, by myself, in less than 5 minutes I know it sounds bad, but I'm waiting for someone to write off a car with one so I can swoop in on their pain, it will go to a good home though, so my guilt of this is tempered
    • I’ve got one on mine and it’s fine, 
    • No, you don't want to plug the vacuum line, as that will turn that side of the booster into an air spring and probably make it feel worse. I'm not saying that the GTR master itself doesn't need a booster. I haven't paid attention to the GTR one to know what size it is cf the non-GTR ones. But when you think about it - they have to do the same job, which is to move a little slave piston a few mm to do what it is supposed to do, and that final action is the same on all the cars. So, it is very unlikely that the GTR MC is any different than the others, because it has the same pedal stroke and the same output requirement. The booster just makes it feel easier. I'd suggest you probably have an actual hydraulic problem. It's totally common on these old shitboxes.
