I'll have to have a look at this, as I've never considered changing style from OEM. Constant tension makes sense, though.gstallons wrote: ↑Mon Nov 25, 2019 5:20 pm# 1 the outlet the coolant hose attaches to looks to be ribbed . Are these ribs in good condition ? If not replace it . Now I keep spring type hose clamps in stock for most all size heater , radiator hoses . I prefer them over anything else . These maintain CONSTANT tension . I've seen water outlet , t-stat housings and just about anything plastic carrying hot coolant fail over time . Do not be afraid to be liberal and replace anything you think is necessary .
Good luck !
As for the ribs, I'll have a good look at the unit when I remove it and let the forum know what I find.
Thanks for the input.
