[TR] Swamp Cooler

[Bud Rolofson]

Listerati,

I’ve had some inquires about the swamp cooler on my TR6 I mentioned in another post so here’s the details.

This only works if you have a scuttle vent that has a pop open lid not the scuttle vent with a plastic grill. 69 through some 72 TR6s had the pop open lid.

I ran plastic "fish tank" tubing off the windshield wiper fluid reservoir (use distilled water) drilled a small hole in the side of the plenum and connected it to a tiny copper tube (from the hobby store) with a dozen tiny holes drilled into it, cap it on the end with a silicone cap. That tube is wrapped with some porous material and held to the tube by using some magnetic clips from Harbor Freight. The magnets hold the assembly to the bottom of the scuttle lid. Tuck the material down the plenum so air flows through and not around it. I press the washer switch for about 6-8 seconds and before long cool air comes out any or all the round vents or out over the tran tunnel or where ever you set your controls for air flow. It only works when moving of course but today I had cool air coming out nicely on my feet and the upper round vents on my body. With the tonneau cover on and covering the passenger seat the cool air was all directed on me. It was 92 today and I drove around for a couple hours and the reservoir still was 1/3 full.

You lose having washer fluid for the windshield but I never used mine that I can remember. I'd rather have cool air.
Plus everything is reversible to stock except for the small hole to the plenum. But I'm never going back. The lid still works as it should and nothing is visible when it's shut.
