Default Re: Shewman's High Flow Thermostats

Okay here it goes, and I know I am going to ruffle a few feathers with this post, but I feel that it is worthy enough to say it, in hopefully helping a fellow barner before he's encounters what I did. This is just my experience and have not heard of anyone else having this problem so, maybe just me... but I am ept enough, not an expert to feel that there was no way possible this was going to work for my application which was from a stone stock standpoint. Shewman's thermostat's there is a photo on here and it's the stat on the right that I used, for 47 Ford 59AB block, I think and believe a stock radiator and aftermarket repro hoses w/ford script? Got the stat's and heated them up actually opened around 185 to 190, but I was okay with that.

My problem came where these stat's fit in the upper portion of the hose near the radiator and they slide inside the hose, no easy task even with dawn soap, didn't want to use anything and hammer on them to drive them in, now either my radiator necks were longer than should be, but I think not, I had to drive the stat so far in that it reached the curvature of the hose neck, which seemed odd, just so I could get the rest of the hose on the radiator neck far enough to sinch up the clamp.
I was uncomfortable with this because of the way the thermostat's open the bottom half of the stat pulls down or let say the inner portion of the stat, and I can see inside the hose to know if it was working or would not work because it was at the curve of the hose? The other side my passenger side, I couldn't get the thermostat ever in far enough to even get it on the neck of the radiator far enough to tighten a clamp? I work a day and a half spent money on various pieces' to use trying to drive them into the hose far enough to get on to the neck so I could try them out. Sorry but after 1.5 days frustration, anger, cussing, I decided anything that I had to work that hard at isn't going to happen, so yes I removed them...now that was another ordeal, because afterr I got them in there, I rinsed them out with a hose to get all the dawn soap out, so now you have a thermostat stuck way in a hose with friction binding of the brass, and rubber hose and trying to figure out how can I remove them now without damage... crap I was pissed. Now, all that being said I returned them and will never try that again with those stat's with my application. I am thinking also that everyone uses different types of hoses like those flex hoses, I can't imagine how it would work in those, but seems some of you have used them I got them installed on your car, how I don't know, like I said maybe it's me, and that's okay...hoping better luck for you if that's the route you decide to take...I have used Shewmans other products with good success...just not those.
