VW T2 Camper Maintenance: A Bay Window Owner's Guide

Written by Petro Olekhnovych, mobile mechanic in Aylesham, Kent

Good VW T2 camper maintenance comes down to four things: regular engine servicing, complete cooling tinware, healthy brakes and catching rust early. Just Kampers says the VW schedule calls for an engine service and oil change once a year or every 3,000 miles, whichever comes first.

This guide covers what is specific to the Bay Window. For the service itself, see our guide to air-cooled VW servicing. Many of the engine faults are shared with the Beetle, which we cover in VW Beetle common problems.

Know which engine your Bay has

The Bay Window replaced the Split Screen from the 1968 model year. Not every Bay has the same engine, and the two main types are serviced differently.

Type 1 engine. Just Kampers says German Bays were offered with a Beetle-style 1600cc Type 1 engine. Heritage Parts Centre says the 1.6 has a high fan housing, with the dynamo or alternator sitting in the middle of the engine bay.

Type 4 engine. From the crossover model onwards, Just Kampers says a “pancake” or “suitcase” Type 4 engine was offered in 1700cc, 1800cc and 2.0 litre sizes. Heritage Parts Centre says the 1.7, 1.8 and 2.0 litre engines have a lower fan housing and a less prominent alternator. Some vans have fuel injection.

Engines get swapped over 50 years, so do not assume the engine matches the van’s year. Knowing exactly what is fitted means the right parts, settings and clearances. Always check the workshop manual for your engine.

Cooling tinware: small parts, big job

An air-cooled engine has no radiator. A fan pushes air over the cylinders, and the tinware around the engine directs that air where it needs to go.

Heritage Parts Centre says all tinware must be present because it is “essential to engine cooling”. Missing or damaged pieces let hot air recirculate and can leave cylinders running hot.

On a Bay, check:

• the fan housing and cylinder tinware are all there and secure
• the rubber seal around the engine bay is in place and not perished
• the fan belt is in good condition and correctly tensioned

If a warning light comes on, the engine smells hot or it starts losing power, stop as soon as it is safe and get it checked before driving on.

Heat exchangers and the heater

Just Kampers explains that hot air from the engine reaches the cabin through tubes connected to the heat exchangers. It notes that the heat exchangers are often seized, missing or disconnected, leaving the van with no heat.

Heater controls that do nothing are a common annoyance. A rusted or holed heat exchanger is a bigger concern. If you smell exhaust fumes inside, stop using the heater and get it checked.

Brakes on a heavy van

A loaded camper is a heavy vehicle, so healthy brakes really matter.

Heritage Parts Centre says Bays had drum brakes all round until late 1970. After that, solid front discs with two-pot calipers were fitted. It adds that late Bays from 1973 had servo brakes.

Drums need adjusting as the shoes wear. Discs need checking for wear and sticking calipers. On either type, watch for:

• the van pulling to one side under braking
• a soft or low pedal
• a handbrake that will not hold the van

Heritage Parts Centre says the handbrake should lock the rear drums easily. If the brakes feel wrong in any way, stop driving the van and get them checked.

The rust spots to check

Both buying guides talk about “the bottom six inches”, and that is where most Bay rust lives. Between Heritage Parts Centre and Just Kampers, the areas to check include:

• sills, outriggers and chassis rails
• the floors
• the front valance and the front beam
• front and rear wheel arches and rear corners
• the bottom of the sliding door
• the front windscreen surround
• the area around a pop-top, if fitted

Just Kampers says sliding doors always rot along the bottom. Heritage Parts Centre suggests using a magnet on the arches to find filler. Just Kampers also warns that water from a leaking pop-top can eat into the floors, sills and chassis.

A wash underneath after winter driving on salted roads helps slow rust down. If you find structural rust in the sills, floors or chassis, get a body specialist to look at it. We do not do bodywork, but we can tell you what we see when we service the van.

MOT exemption is not a free pass

Heritage Parts Centre says European Bay production ended in 1979, so every European-built Bay is now over 40 years old. GOV.UK says vehicles built or first registered more than 40 years ago do not need an MOT, as long as there have been no substantial changes. Changing the chassis, body, axles or engine in a way that alters how the vehicle works can count.

Many Bays have had engine swaps, so check whether yours still qualifies. GOV.UK also says you must still keep the vehicle roadworthy. Using a vehicle in a dangerous condition can mean a fine of up to £2,500 and 3 penalty points.

How we can help

We work on air-cooled VW engines, including Bay Window campers. Find out more about our classic car servicing in Kent.

We come to you across Aylesham, Canterbury, Dover, Deal, Sandwich, Folkestone and the villages around them. We can service the engine, check the tinware, brakes and fluids, and do fault finding on site. Engine rebuilds are done in a Kent workshop; see our guide to air-cooled VW engine rebuilds.

Labour is £30-£50 per hour depending on the job and its difficulty. Parts are extra, and we agree the price on WhatsApp before any work starts.

Frequently asked questions

How often should a VW T2 camper be serviced?
Just Kampers says the VW schedule is once a year or every 3,000 miles, whichever comes first. Check the manual for your engine.

How do I tell a Type 1 from a Type 4 engine?
A Type 1 has a tall fan housing with the dynamo or alternator in the middle. A Type 4 sits lower and flatter. If you are not sure, send us a photo.

Is it safe to drive with tinware missing?
It is not a good idea. The tinware directs cooling air, so missing parts can make the engine run hot.
