Tech Notes:

Volkswagen Cases 1200-1600 thru 1970 came with "small" oil galleries and single relief oil systems. The original oil coolers installed on them used the 111 117 151 seal. However, with the introduction the dual relief cases in 1971, the oil galleries were enlarged and a "stepped" seal was introduced to install the small hole oil cooler onto the large hole case. As time went on, Volkswagen eventually upgraded the replacement cooler with the larger holes, but now it required this same "stepped" seal to be used when installing it on an early, small hole case. Seal Kit 111 198 029 comes with two of these stepped seals and they must be installed as shown below to prevent leaks. The same applies if retro-fitting a Doghouse Style Cooler stand to an early, small hole case. How do you tell if you have a small hole case? Check the engine number as well as the size of the holes on the case. Beetle (Engine # B600001 on), Kombi (Engine # B5116437 on) and all engines beginning with 2 letters (AB, AE, AH, etc.,) are usually dual relief cases with large (10mm) holes. All other cases are usually single relief cases with small 8mm holes).
