How to do a Sea-Doo Coolant Flush on a Jetski<\/h2>\n\n\n\n

A Sea-Doo Coolant Flush on a 4-TEC Rotax engine is a lot like a modern car engine. It uses Type A coolant to keep the engine at the correct operating temperature. If you haven’t replaced the green coolant in over 200 hours or 2 years it’s time to get it done.<\/p>\n\n\n\n

My Sea-Doo GTI jet ski coolant was well overdue at 3 years. Coolant will start to lose its anti-corrosive properties and fail, so best to get it replaced at the manufacturer’s recommendations.<\/p>\n\n\n\n

Replace Sea-Doo Coolant<\/h2>\n\n\n\n

Now you can take your Sea-doo 4-tec to your local dealership, and start handing out your hard-earned cash, or you can do it yourself. The Jet-ski coolant flush should only take around 20 minutes. Your owner’s guide manual will say, it has to be done by the dealer,<\/em> but it is really easy to do it yourself.<\/p>\n\n\n

First, run into your local auto supply store and pick up some Type A Coolant, usually made of Ethylene Glycol<\/b> together with some protective additives. It is mixed with water to produce coolant. You can either get the ready mixed stuff or the concentrate and mix our own with Demineralised water, 50 – 50 mix.<\/p>\n\n\n\n

5 Liters will be enough to completely change out your jet-ski coolant.<\/span><\/p>\n\n\n\n

\"\"I always use Calibre<\/a> Anti-Freeze\/Anti-Boil Type A, 5 years or 250,000km protection here in Australia. If you would like the official Genuine BRP (Ski-Doo, Sea-Doo, Can-Am) “Red” pre-mixed antifreeze\/coolant.<\/a> Then you can get it from Amazon.<\/span><\/p>\n\n\n\n

It comes in 1-liter bottles.<\/span><\/p>\n\n\n\n

If your coolant is green then stick with the green color. If it is red then stick with the red coolant. But saying that there is no issue from completely flushing your coolant and then swapping over to another color. Just don’t mix the colors.<\/em><\/p>\n\n\n\n

Sea-Doo Coolant Flush Procedure\"Sea-doo<\/h2>\n\n\n\n
    \n
  1. Remove the coolant pressure cap from the overflow plastic tank.<\/li>\n\n\n\n
  2. Carefully remove the stainless drain plug from the bottom of the ride plate using a hex Allen key and drain it into a container. Do this where spillage won’t matter.<\/li>\n\n\n\n
  3. Pour demineralized water into the overflow tank and flush out any remaining coolant. When it’s finished draining pour a 50\/50 mix into the overflow tank.<\/li>\n\n\n\n
  4. Have someone watch the drain plug as you pour the mix in, as soon as there are no air bubbles, screw in the drain plug. This is optional but helps not to have to re-top up coolant next time you go for a ride.<\/li>\n\n\n\n
  5. Fill the overflow tank to the correct line. Not too much, too little.<\/li>\n\n\n\n
  6. Replace the overflow coolant tank cap.<\/li>\n\n\n\n
  7. If you have a torque wrench torque up the drain plug – 75lbf.inch<\/li>\n\n\n\n
  8. Run the Sea-Doo jet ski engine for 30 seconds, and recheck the coolant level. Top up if required.<\/li>\n\n\n\n
  9. Failure to flush and top-up your cooling system can cause your boat, jetski, or car to overheat<\/a>.<\/li>\n<\/ol>\n\n\n\n
