I recently purchased one of the cheapo snorkels and was at a loss what to do about the overflow bottle.
After chatting to Har05L, he said he retained the original overflow bottle in the original location and sent me some pics. I have documented some basic install instructions which i have sent to quite a few members, so thought I would post them here for all to use. Click the photos for larger image.
Additional parts required - 1 x 8mm barbed hose joiner and 300mm of water hose to suit existing hose (about $8 from any repco/supercheap etc)
1. Using a hacksaw or grinder remove the retaining tab from either side of the bottle and use a file to smooth off the edges to get them as flat as possible (photo 1, 2, 3) - Do not remove the pointy tab at the bottom of the bottle as it is part of the mould and will leave a hole in the bottom of the bottle.
2. Join the coolant hose and the new section of hose together using the joiner and then run underneath the snorkel pipe to exit where the old hose used to (photo 4)
3. Attach the hose to the overflow bottle
4. Add a dab of silicone to the rear of the bottle and then using your left hand to lift the metal pipe slightly, place the bottle back in the original location and push underneath the plastic clip holding the metal pipe until it clicks - the silicone will ensure there is no movement due to vibration- (photo 5, 6, 7, 8, 9)
5. Refit the air filter and air box top
Hope this helps
