Discussion on radiator hoses and thermostat

submitted by Jim Martin

I was sold a Stant 13858. The only possible added benefit of the new thermostat is that it has a pressure relief on it.

Installed the thermostat tonight, and replaced both upper and lower rad hoses. I ordered a lower hose from Ross, (the Gates one from this wiki), and it fit perfectly. I had a heck of a time finding the upper, but it turns out that it crossed fine to a DAYCO 70986. You will see that it is a little long, but a good knife blade took care of that.

I took several photos of the original braided type hose to the replacement hoses and the thermostats.

This is the offset 180 degree thermostat mentioned in previous posts.

Thanks for sharing Jim.
