The seal was worn just enough so water would be pumped out between the driveshaft and seal as well as the pump outlet. 09289-10002 (oil seal) that sits on the pump housing for the drive shaft.

It had sat for 6 years.but looks almost new.FOUND OUT it was the seal. SUZUKI DT4 COOLING SOLVED.I had the same problem with cooling on my 1989 suzuki dt4.

So i left it with them and two weeks later i got a phone call, they told me that there was a crack in the block and as the engine got warm the crack opened and the water exited through the crack rather than through the 'pee' hole, so i assumed the engine was now broke as the cost to repair it would out weigh the value of the engine, luckily they only charged me for the gaskets and not labour so my bill was only ?30 rather than the quoted ?120.Īnyway when i got the engine home i ran it in my bucket of water, 15 minutes later and it was still pumping water, 30 minutes and still pumping water, so i took it out up the river and two hours of running she was still pumping water.Īnyway if you blow in the water tube that might give you an indication of where the water is going, plus by removing the big slotted bolt will tell you if the water tubes around the engine are blocked, the slotted bolt is look at the engine with the prop facing you, follow the leg up and its in the center of the engine at the top, just under the power head, if i havnt explained it well enough then i will add a picture of it. While i was in the shop they did the same thing then they remaved a big slotted bolt at the front of the engine and air came out!! he then told me that the water tubes that go round the engine are blocked and will need to be cleaned out!! So i took the bottom leg off again and blew through the water tube (i put a piece of fuel pipe on the end of it) and found that air was exiting somewhere in the leg rather that through the 'pee' hole, so i rang a marine shop to see what this could be.Īfter speaking with their mechanic i took it in for them too look at it, I changed the impellor as i knew it would need one as very little water came out the 'pee' hole, but when i put it back together and ran the engine it pumped a good amount of water for about 5 minutes and then stop. The chances the emulsion tube is clogged.I have the same engine and had a similar problem with the water pump and the engine not pumping water as good as it should, so this is what i did. Now if the emulsion tube is clogged it will not allow fuel to the combustion chamber. The fuel is atomized so it will be hard to see. When the fuel goes through the carb through the emulsion tube to the calibration pocket and enters the carb venture that where the air is introduced. On the idle circuit there is a calibration pocket with tiny holes behind the butterflies that allow fuel into the combustion chamber at idle and cranking speed. When the piston moves it creates a vacuum pulling fuel up through the tube into the combustion chamber. The carb has a tube (emulsion tube) that runs up the center of the carb.


If the plug wire is damaged it will ground before sparking under compression.

The plug should not shock you if it is connected.

Remove the spark plug install gauge advance throttle to wide open crank engine. To check compression you will need a compression gauge. But you can take the carb to a shop and pay them to clean the carb for you. This is a very expensive piece of equipment. The ultra sonic cleaner is a tank with a solution that vibrates the carb clean.
