box heater

Covering this yet again (because I got PM's about it last time). If you are replacing the heater valve (likely due to leaking), do yourself a YUUUGE favor and replace the heater core also. I now replace the original core with a Lada unit from "LADA POWER". They are $25 spank'n new, the correct...

I watched @markx19 (Mark Weinberger) latest short video on his "Green Machine" series number 20 where at about 1:00 in he shows reinstalling a fan shroud for the early year non-AC heater box. I've just recently done mine (thanks again to @Mark Olson for the upper box!) and I did not see this...

I now have the nonAC heater box all put together and ready to install. I ended up using the spider heater core and modifies the heater box. First I ground off the heater core support tabs and flipped the cable support just like everyone said. Than I machined off about 3/8 of an inch from the...

Folks, I recently posted a thread in Workshop forum asking about replacement heater cores. @Jefco suggested a 124 core with some customization to the heater box. He posts pics of the size differences here I used it as direction and did the following: I bought a core from VicksAuto Removed the...
