LR3 heater core
Hello,
I have the common lr3 heater core clogging issue. Poor heat on drivers side, blender doors and motors are fine. Very good local Indy LR shop charges $1020 for the job, say they do it 3-4/month. Ive read that it is a hard job but have not seen a DIY or specifics. I looked in the service manual however and it looks straight forward. Drain coolant, remove passenger side interior paneling, heater core slides out after removing hoses. Assemble and refill. I've been wrenching for years however never done a heater core.
Anyone done this? Is it as easy as it looks in the manual? Talk me in or out of it.
Thanks!

All interior trim parts went back in easily. I used light duty threadlock to avoid squeaks and rattles.
Don't let anyone tell you this job is the hardest thing... It really isn't. At all. It isn't.

Also, for anyone having the same issue, I found a repair guide.

Nissen heater core?
The core being on a Nissen makes sense; I cannot see someone designing a different heater core for every vehicle on the road - well, maybe Land Rover does.
