Heater Core Leaking R33

[plaganis]

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.

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
