Hello!
I'm the current guardian of a 1973 bay window Westfalia, and I was hoping for some advice on how to look after it. It's my first VW and I'm no mechanic, but in the 6 months that we've had the van I've successfully replaced the shift rod coupling and renewed the accelerator cable. I'd like to continue to learn about the vehicle by performing as much DIY maintainance as possible. To that end, I'm hoping someone has the patience to help me with the following:
I'm due an oil change (I think! We've done about 3000 miles since the last one). When we got the van, we had a mechanic change the oil, and he also replaced the little copper washer that seals the sump. Do I need to fit a new washer with every oil change?
When going downhill under engine braking, the engine pops and splutters a bit. Is this normal?
When starting cold, the engine splutters and pops quite a lot. It also shakes around quite a bit until it's warm. To my novice mind, it seems like some of the cylinders aren't firing properly. It runs fine when it's warm. Is this normal?
When cornering (turning left), the front left wheel squeaks slightly. The squeaking is stopped by touching the brakes. Could there be a problem with the brakes?
Is it safe to simply top-up the brake fluid reservoir, or do I need to drain and refil the whole system? I've no idea how full it was when I got it, but it seems very low now (under a quarter full). I only checked it when I noticed the squeaking... What do I top it up with? How/where do I check for leaks in the system?
The previous owner (of 15 years) disconnected the cables from the dash controls for the heating, leaving the hot air permanently on. He advised me not to reconnect them, claiming the engine would overheat. The mechanic who serviced it when we got it suggested that the heat exchangers weren't properly set up, which explains the strong smell of fumes in the cab. What exactly do the heat exchangers do? Is there a good reason to leave the heating on all the time? Is a smelly cab something I should put up with?
I'd also add that I'm currently living in northern Spain, but because I don't really speak Spanish, I don't know where to start looking for a garage that could help me with the vehicle. Anyone have any suggestions?
Thanks!
Leo
