Does anyone know what size the lower radiator hose is on my 2018 Ck3510hse . I'm thinking putting in a lower radiator hose heater and I just don't want remove the hose to order the right one. Tractor starts great but runs ruff a on cold days for a couple of minutes. I just want to give it a helping hand warming up.

While I'm unsure of your CK3510hse, maybe this information can correlate is some helpful way.

My DK45se hst lower radiator hose is 34mm ID, and 44mm OD

Kats 1.5" heater (16600) is 34mm ID and 38mm OD with a 40mm bump out lip and the edge. This worked out to be a great fit. Stuffing the 40mm Kats lip into the 34mm hose wasn't too bad, and because of the ID's being the exact same, there is no restriction to speak of.

You can see it here. The temps I recorded after 12hrs of on time at around 37F ambient temp.

Perhaps if the OD of your hose is the same as mine, this info could be useful.
