How do do know if your snorkel is working or how can you test it |

Block the top and see if the motor struggles to stay on |

Deego, you sure are asking a lot of snorkel questions (*see below) . Stevo is correct - take the ram off and block the end with your hand. The engine should stall. it will take a few seconds and you should feel lots of vacuum. I think you'll find it won't stall, and that's not because the snorkel is faulty, it's that there's lots of spots for air to be drawn in to the inlet. Suzuki air boxes in 1.0/1.3 litre sierras are badly designed and aren't very well sealed. They also have a hole in them to let coarse dust/water out. This can actually let enough air in to keep the car running. There's also the warm air mixer just before the air filter. You need to seal this up well. * I'm interested in why you are asking so many snorkel/inlet questions. It seems like you are a noob, and it's great to be asking questions, I'm interested in why this is your current focus. Whilst having a good snorkel/precleaner setup has advantages, are you asking about this stuff because you are doing lots of deep water/bog holes, or because you want to? Don't be offended by me saying this stuff - if you know it all already that's fine, it might help out another noob. There's LOTS of stuff you need to get your head around before you worry about the snorkel. If you're interested in how well a snorkel seals, it implies you are keen/worried about deep water, not some splashes. Firstly, have you seen where the air inlet is in a stock sierra? It's beside the battery. This is an area of the car that stays very dry in deep water - even water that's well over bonnet deep when you are in motion. It's also quite high - it's well over waist deep and is roughly level with the bottom of the steering wheel. I don't know about you, but I don't want to have that much water in my car, snorkel or not. Understand the difference between water depth and the bow wave. I've been through water washing over the bonnet but wouldn't wet the back bumper. There's a huge difference between water depth being pushed and the actual water depth. You need to have breathers on your diffs, transfer case and gearbox. I've filled my transfer case with water/mud and that's without a snorkel. Sierras have a mechanical cooling fan. 1.3's have a 4-blade fan that's renowned for breaking when the engine is revved in water. loosening the fan belt, or fitting a vitara viscous fan is a very good option for water crossings/ deep mud. Do you have anything on/near the floor thats going to die when you fill the car with water? Sierras don't seal very well. When you stop in deep water (and it will happen) the car will start to fill up quickly. Make sure you don't have carpet glued down, anything that's going to get water damaged under the seats or flat on the load area, and make sure any draws/false floors etc are made of water resistant material, not chipboard or MDF. Make sure things you need to keep dry, like your jacket, maps, mobile phone, first aid kit etc are all high and dry and/or in waterproof boxes/bags. Be prepared that your clutch will stop working if it gets mud in it. This can be impossible to fix in the bush. it might slip if it gets wet. Don't keep slipping it, let it dry out. Carry WD-40 with you to dry out ignition parts. The ignition will start to break down if there is lots of water plashing about the engine bay. This is normally if you are using high revs and/or rocking 1st/reverse to try and get out of a hole. Carry a small tarp as a radiator blind. These are very effective at keeping water out of the engine bay. Remember that it's not just the inlet that's the problem, with wet ignition your car won't take any load and that means you might not be able to drive out of a hole, the engine will be likely to stall, not restart, and then the water depth inside the car will equal the water depth outside. KEeping water out of the engine bay is critical. Bear in mind though that a blind only works when you moving forwards. if you stop, the engine bay will quickly fill. Assess whether you even need to go there. Whilst in some parts of Australia, deep water crossings are part of moving around, many people wreck cars/engines in crossings/bog holes they didn't need to drive though. Never tackle a water crossing or bog hole you aren't 100% confident about alone. Things can get very out of control very quickly if you are by yourself. Be much more cautious at night. Water crossings look VERY different at night and the right line is normally impossible to spot. If the water is muddy and your headlights go under water you will have no visibility. Hope some of this helps. Steve. |

yes it is easy to install breathers they are a couple of good write ups on here a simple search should help you out |

I use selastic to seal the air box lid, and all hoses etc. That little hole in the bottom of the air cleaner to drain debris out, can let a significant mount of water in. I drilled the hole out, fitted an elbow and ran a line to the front with a tap on it ( I used garden watering fittings). When I lock the hubs, I close the tap. Dielectric grease one the plugs and leads and dizzy cap to help seals things avoids the wet sparky issue. Also be aware that your fuel cap may let water in. If doing a lot of water crossings, consider a marine type fuel filter which can seperate the water, and be drained away easily. Vit viscous hub is a safe option (Ive had my softop in a lot of water, stock fan didnt do any damage, however, can never be sure). Ensure you have a crap radio and speakers, because you soon will. Wheel bearings hate bogholes... and the car fills with mud These two reasons alone why I now avoid bogholes. |
