Here is My engine bay with items labelled like
Carburetor
inlet manifold heater pipe
fresh air hose
crankshaft pulley
alternator
Dizzy - distributor
etc
this is mainly for newcomers
Note: this has a few odd parts that are Not in Normal standard beetle engine bays
like- ATF Cap - Control Valve - fuel pressure regulator
and the external oil cooler...

such pretty colours
Thank you sooooo much.
Nice to get some basic info about VW's
I salute you 68AutoBug.
May your VW never run foul!
Why have you got your oil cooler in the engine bay?? Especially right near the fan? Would certainly benefit engine oil temps to have it under the car and away from the cooling fan.

Many thanks
I get asked a lot about parts, which the new or younger drivers want to know about
as its hard to ask a question if you don't know what the part is called...

PS: I have done away with the doghouse oil cooler and am
using the original fan shroud..
the Oil cooler will eventually be located under the car along with an oil thermostat and spin on oil filter..
but the oil cooler is running cool now with the temperatures we are having.. It would heat the cooling air in the summer...
Engine lid is open at top all the time..

the yellow strap is the covers to the adjusters for the rear drums!!!

Dont suppose youd be willing to illustrate what/how the doghouse/shroud works?
No one seems willing to part with the information
basically, the "dog house" is a section which sits out from the front of the fan shroud (front = front of car), which houses the oil cooler, the hot air which passes thru the oil cooler then is vented to atmosphere. in older style type 1 engines the oil cooler was in the direct path of the cool air on its way to cylinders 3 and 4 so the air cooling the cylinders and head was already heated, this created heat issues and was basically a somewhat flawed design, the doghouse cured this.

Im still a litle confused, where is the oil cooler and what does it look like?
Also how does the shroud work with the piping that goes to the exhuast? thats puzzling me most
Damn, I had a spare engine that belongs to a mate of mine sitting in my carport untill yesterday, when I took it back. I could have taken some photos for you.
From your ole' mate Jeff
Ah that sucks, thanks anyway!
😊
the piping from the shoud going to the exhaust is in fact not going to the exhaust but to the heater boxes, which are essentially tubes surrounding the exhaust headers. this heats the air as it flows past and down the heater channels on the side of the body and if you open your heater flaps, into the car.
the oil cooler is kind of like a mini radiator but for oil not water, on older engines it sits inside the fan shroud, about inline with the distributor, oil flows up into the cooler, the air going past reduces the temperature and then it flows back into the engine. in a dog house setup the cooler is in the same spot but offset so it sits outside the flow route of air heading for the 3 and 4 cylinders and their head, some air is then directed to the dog house cooler and then this air is vented out of the setup so that the air to number 3 and 4 is not pre heated by the oil cooler.
make sense?

Wow, that makes perfect sense, thanks alot!
I had an idea about the heating but that just cleared it up
I heard somewhere a while ago that people used to die from exhaust fumes from this set up
That doesnt sound right unless the exhaust was leaking into the heater box
i got a pile of engines under the house
ill make u nice preddy labled diagram tomoro
Oh no thats not necessary, i go the jist of the oil cooler now
Theres a few more things im uncertain about but this was just bugging me
Thanks alot anyway
Im glad theres people ready to help a newbie 🙂
milestones, prior to about 1962 vw had a different type of heaterbox that used air that had passed over the cylinders/head. they are called staleair heaterboxes (as opposed to the freshair setup on later cars), if you had a leak on the cylinder/head joint you could get carbon monoxide in through your heaters.
you can still get exhaust into the car even with "fresh" air heating if the exhaust has holes in it. Type 4 kombis seem to be the worst for that. Burning oil fumes get in too if you have leaking pushrod tubes or tappet cover gaskets. I doubt anyone has actually died from this unless it was their intention. You'd have to be a masochist to keep the windows up with the car full of fumes. Although I guess it gets pretty damn cold in other parts where you might put up with a bit more fumes than here.

I thought i would post these anyway.
Here is the doghouse cooler on a 1600 Dual port motor.
This is it without its shroud on you can clearly see the oil cooler at the back.

well to bad your getting it anyway
i worked a long and hard 2mins making this
im not quite as pro at MS paint as Lee but you get the idea
ive seen a few to many engines missing the ducting for the oil cooler
to many non vw savvy ppl think oooh theres some weight reductions to made here.....
🙄Thanks alot guys, that was alot of help!

Why copy when you can own an original ?
Meyers Manx AustraliaWow I'm glad I cam in to this thread. I just learnt a good deal of stuff. Thanks guys.
Oh and would connecting those heater hoses to the box underneath make it a bit warmer in the cabin? Mine are just blocked off. Would it be a big job?
well ideally the heat exchanges are removed and replaced when they block off the heat pipes on the engine, but if they are still there yeah the air goes from the engine through the heat exchangers (plugs into the top) and into another pipe (on the back of the heat exchanger) that leads to the rear of the cabin.
wow i even learnt something..
ive had a look at my engine when running but am yet to see green directional arrows wizzing about 😂
btw a good thread for peeps who are not in the know
maybe this should be moved to the tech talk section as it will prolly fit in best there

pauly my engine is just special
unless you live in antarctica, if the heaterboxes are still fitted to the engine you need the hoses from the shroud connected to them regardless of whether u want heat or not
the heaterboxes cook the heads without the hoses hooked up
thats why u fit J pipes if u dont want heaters
so is it alright to leave the pipes off with extractors? This wont detract from cooling capabilities?
There are three types of people in this world - people who can count and people who can't....
if you have extractors with no heater boxes then block off the outlets on the fan shroud

thanks for the inside shots and labelled shot of the fan and oil cooler/dog house....Ive never seen inside before...great to learn something!
