time for more info on the Perentie/Defender Heaters!
I am removing/replacing the Brake Booster on one side and removing/replacing the Heater box on the other side of the firewall. This is a pre-cautionary check for firewall rust and to replace the footwell anti-water ingress seals. My Perentie is close to 30 yrs old and the anti-water-ingress foam seals may be crumbling.
Certainly the foam seals inside the heater/blower box would be crumbly and decomposed.
I was going to dismantle the heater box and recondition it as per the video from Britannica restorations (

----------------Lately some new heater boxes showed up at the AFM Auctions.
"We" got 4 heaters in a lot for about $300. Good value to say the least! Complete with matrix and loom. And one for each Perentie in the family.
They are new in box. They appear to be the Bushranger unit CYG9196 (with suppressor) yet the LRA cartons have a sticker saying CYG9197.
Q1:
I will replace the heater hoses. Can any member with more experience see a problem running longer heater hoses along the side of the LHS wing to get the heater hose off the engine and away from the hairdryer?
Q2:
In the attached Perentie firewall photo (not mine) I have outlined in yellow the blower outlet or entry into the cabin. You can see the remains of the foam gasket adhesive and it indicates the heater outlet for the air is double the size of the cutout in the firewall. Anyone know why? The video series linked above hints to enlarge the cutout to suit the blower... it that ok? Is an ADR in play or something?
Q3: In the photo I used red arrow to indicate the mounts. The higher mount on our Perenties have 2 bolts and a basic bracket to the heater assembly. The new units we purchased are presumed to be from the Bushrangers/TD5 era and have no corresponding holes for the bracket. No bracket at all. Maybe this is one of the little Solihull-assembly-worker-time-and-motion-consuming items that LR engineers made redundant with a piece of plastic or something?? Do I have to go to a LR Workshop, find a TD5 and check how they secure the top of the heater or does a member here know?
