Cabin fumes
Hi guys, I've redone the engine and reinstalled it but I get allot of CO fumes in the cabin. What can I do to make it a more breathable ride

Re: Cabin fumes
Exhaust fumes in a Beetle are most likely getting into the cabin via the heating system. I generally disable the heaters on all my ACVWs because the heat exchangers tend to be worn and pump fumes into the cabin. If your heating system has been disabled, then it's a good idea to block the pipes where the heated air enters the car. Aerosol caps work well for this.
If you must have working heaters, then you need to source new heat exchangers (NLA) and ensure all the flanges and joins in the system are properly sealed.

Re: Cabin fumes
As Fig said, when your car is new, and good and clean and fresh, the heater works like a trooper.
But as it ages, the engine leaks oil and fuel, and the air blower picks up all these fumes and pumps it straight into the cab.
Take the pipes off, block them with caps, make sure you close the holes in the tins, or the engine will overheat, and buy a thick jacket or grey coat.

Re: Cabin fumes
My beetle has come without the heat exchanger system and only a very loud single outlet exhaust.
Is it worth the money to buy new the complete system to get the heating system going and the original two exit exhaust pipes like it was originally designed ?
I like original as much as possible, but if the cost of this is extreme and the heating system is a bad design, then rather not.

Re: Cabin fumes
Very few heaters will ever be able to match the original VW heater.
If you get a used heater, it will probably leak and let fumes into the cabin.
But you talk about buying new.... the new heaters still work well, but nowhere nearly as well as the original. OK, I am talking about aftermarket heater boxes here. If you can get new replacements from Brazil, then those should work pretty well.

Re: Cabin fumes
Who makes aftermarket type in RSA ?
Shelly's had an old set of heat exchangers for R380 per side, but I forgot to ask if that included the exhaust piping also, it looked like it was built around the exhaust pipe.
The old German there said nobody realy uses bettle heating systems anymore, but I would like it working for my daughter if I can.
Still need to red my manual to see how it is connected to everything. I see two cable end's exiting the chassi near to the engine so assume they are still ok to connect.

Re: Cabin fumes
Dont do it. Those are 40 years old and guaranteed to leak.
No-one makes aftermarket heat exchangers in SA. You'll have to look into people like CSP in Germany, Machine7 in the UK and maybe one or two others. But they are properly pricey.
CSP has them for 100euro each side, CB has them for $300 for the set. After shipping and import duties, I'd be surprised if you get by with under R7000 - these are new stock.
A good set of rubbers and blanking off the front bonnet vent goes a long way to warming the beetle up. I survived a JHB winter (3) like that and after a few minutes, the beenie would come off and the jacket would be unzipped.
Not ideal, but you can warm up if you stop the air from moving around the cabin

Re: Cabin fumes
Just enjoy the smell and save a couple of rands on buying a bottle. Keep inhaling those fumes. After a while you will love your Vw too much

Re: Cabin fumes
Scored this second hand set in good nick and tested Exhaust side with no leaks. Not bad for R300 for the set.
One step closer, now just need exhaust silencer and heater hoses.

Re: Cabin fumes
Your problem is the engine sucks air from outside( that is if all your engine compartment seals are in places and working)
The air then travels past your leaking oil cooler, and over the heat ex changers, that also have oil dripping all over them.
The fumes are mainly old oil smells and burnt oil, not so much CO2
Good luck with the heaters, but get your kid to tell you when she gets headaches on the way to work and back.
In cold JHB winters, I normally had a fan heater that was placed next to the car with door open and blowing into the car before leaving for work, made me nice and toasty, and smiling all the way.

Re: Cabin fumes
I am busy sorting out the few oil leaks I have and replacing the engine bay seals at the same time.
I guess I am new to this and will probably learn the hard way - at least it isn't costing too much just yet.
Will drop a note either way when it's done to see how it turns out

Re: Cabin fumes
Turns out my heaters are working now that the engine is back together and no fumes, just nice hot air.
Only fault is the left box heater flap does not seal fully when closed. The mechanism works and the flap is shut, but it bypasses slightly.
Could I take a thin piece of silicone rubber and stick it to the flap with that Red Devil red gasket maker ?
I used the Red Devil to glue some 6 mm Silicone Strip together already to replace the rubber sleeve on the heater box outlet where the pipe clamps between heater box and vehicle and the butts stuck together very well.
