Huh??? Are you absolutely sure the VX Thermostat is located on the bottom of the engine (I've never heard of that before on any type of automotive engine)???
Please see the engine diagram lay-out in Post #6 of the below thread by member "Deer Magnet". Part #1 (labeled "NSS" ~ aka Thermostat & gasket #66) of Section B shows that section B is mounted top-front-center of the engine block, and in VX-KAT's pictures of this thread show that it's located directly underneath the front center air snorkel coming from the air cleaner at the very top-front-center of the engine (not bottom of engine).

Unless I'm mistaken; changing a thermostat on a VX is very easy and couldn't be more simplier, as it is located top-front-center of engine within easy reach.
