1993 L Series leaking heater core

eaglebrad · Post by **eaglebrad** » Thu Mar 13, 2008 8:23 pm

Would really appreciate some guidance on locating a service manual for a 1993 L series 4 x 4. The heater core has decided to spring a leak and I would like to know the procedure for removing it.

Anyone had any experience removing the heater core. Have done it on other vehicles with varying degrees of pain. (On my nissan pulsar I had to remove the dash). Hopefully the suby is not as difficult.

Thanks guys.

Thankyou very much. I did a search for posts by El_Freddo and found it. Doesn't look too bad.
Thanks again for your assistance.

Also be aware that you can quite easily bypass the heater core. Takes a couple of minutes and will enable you to continue driving the car for as long as you want - no leaks but no working heater until u replace it

Here's the thread you're after about the dash removal.

Enjoy.

I would sure appreciate some instructions on how to bypass the heater core as I would love to save myself another trip to the mechanics. Just had the water pump done in my 94 L Series Sports Wagon , now the heater is leaking on the passenger floor. Cant do the job right now so Im looking for a quick fix. Thanks would appreciate it. Also, for when I do pull the dash out to fix the problem, do I have to buy a whole new heater core or can I have the one thats in there reconditioned?

Remove the spare wheel and you'll see two 3/4" hoses running from the top of the engine into the firewall. These go to the heater core. Disconnect them from the engine and use a short length of hose (but not so short that it kinks) to join the two pipes coming off the top of the engine, and bingo, heater core is bypassed. Might be an idea to plug (or join with hose) the two holes in the firewall too.

yea mine blew a few months ago, i had to undo all the dash bolts, undo all these clamps in funny places and undo most of the electrics. I managed to do it withought getting the whole thing out but a bit of force was needed to get the air box out and in again cos its a tight spot
