Rear heater bypass / removal

[musthave]

I've searched extensively but can't find instructions / methods / options for bypass and removal of rear heater.

Does anyone know a link or know options?

What are the benefits of removing?

i just bypassed my rear heater this past weekend... I did it because one the metal lines to the rear heater started leaking...

Some people bypass the rear heater to avoid leaks from corroded rear heater pipes and/or avoid the cost and hassle of replacing those pipes.

My metal lines needed to be replaced due to rust but I didn't want to ditch the rear heater. I simply cut the lines back to where they where like new and replaced with quality silicone heater hose. couple constant tourque clamps. I ran the hoses on the inner frame rail. Been 3 yrs with no issue's.
If you want to delete completly the pic above tells/shows how to go about it.

THe bottom two hoses are the for the rear heater, just bypass them. The benefit is that those lines can be in really bad condition and close to failure. The drawback is, no rear heat and loss of coolant capacity.

Can the two hoses that go into the bottom of the rear heater just he plugged off if the blower under the seat is removed? Or do I need to connect them with an elbow or something?

no you would need to loop them together, one line is coolant in the other is coolant out. or you could just loop it out at the firewall, less chance of a coolant leak from rusty 20+ year old metal lines
