Heating: best point to connect to coolant-circuit?

[TobiasM]

Hi guys!

I am getting my Chally "street legal" in Germany, which requires a heating / window defogger.

As the complete stock heating-box is - supposedly long - gone, I today purchased a nice, compact heater-box with integrated blower from the junkyard.

But we didn`t find a "connection" at any spot at and around my Chally`s engine, which seems to be made for connecting the heater-box to the coolant-circuit of the engine. Could you guys help me please, with where it`s best to connect heating to coolant-system?

Below two pics of my engine-compartment.

Thanks in adcance!

On the pass side of your water pump housing, on the top, you have 2 plugs installed where the 1/2 inch and 5/8 heater nipples go to install your hoses

Hi Al. Thanks for the hind, which did help a lot...

I attached a close-up-pic of my water-pump-housing, as I found 4 plugs in there. Which one is the smaller one (1/2"), which the bigger (5/8") and which of the two do you use to connect engine to heater core and which one back from heater core to engine? I don`t have AC.

Another thing, which I learned from yearone-book: there a two different bigblock water-pump-housings a) until 1969 with 2 5/8"-heater-hose-fittings and b) 1970 upwards with one 1/2" and one 5/8"-fitting. My enginge got an ID-boss saying "E440", meaning "1969 440". My car was also built in fall 69.
Can you distinguish between the two housing types? Which one do I have?

Antother big thanks

 :eek4:sorry,im no expert and its hard for a novice to make way between all the taiwan parts thats stuck to your engine :misbehaving:so i say nr 1 and nr 4.but before you buy hose connections for the waterpump housing,check what nr,s on it ,as i think its threads for the hose connections changed between 69-70.dont remember exactly,but my -70 with ac has one 5/8" and one 1/2" hose connections(15$).

1  and 3 is for your heater hoses.  1/2   and 5/8     number 4 is for your water temp sending unit for your factory gauges

the housing last 2 numbers usually reads 87 i think for 68-71  but other numbers would also be for that yr as well.
