Cooling water pressure df115

[Freddy jakob]

Does anyone know what the water pressure is at idle and full speed on df115 ?

[Murray]

I looked in my service manual and I couldn’t find an specifications given for my engine(2009 DF90A).

Suzuki uses a low-pressure/high-volume 15 psi system, the gauges will generally show around 8 to 12 psi at WOT.

I’ll post the link in a separate post incase the owners of this forum won’t allow the link

Hello. Thanks for the good information and feedback. It is good to have good knowledge in connection with troubleshooting

I just used Google. I’d be interested in knowing if the above link is accurate.

Thanks again Murray
The link was good and useful. It is very low water pressure at idle and difficult to measure especially low pressure system. If you have varied pressure, you do not know where the limit goes until the engine dislikes this.
