Keeping the PT cool

[jwangelin]

It was a rough winter. Early this winter I was doing a lighting upgrade and between my stupidly and some loose wires my PT425 went down. I blew both coils on the Robin engine. Fortunately I found a used set. Now it’s time for me to overthink things in the spring since it’s too wet to do anything. Seems like heat is the biggest enemy of the PT. I cut some luan and set it in the back of the engine figuring it will prevent the recycling of hot air. I also set a side fan but only with a manual switch. I would like to set it up and activated like the trans cooler but not sure where it would be activated.
Has anyone moved their engine oil cooler or installed a larger one? Finally finished moving the lights to a better location.
Any suggestions?
Thanks!

You could add a high amp relay to the little temp switch that PT uses for the PTO cooler and have the relay output drive the two fans. If it were me, I would add a new power wire for both fans and fuses.

Nice mods!

All the best, Peter
