in hose thermostat -(no housing)

yes · **Joined:** Mon Sep 26, 2011 11:32 pm **Posts:** 28

i am somewhat new here so i want so say what a great resource this has been.
I believe my thermostat is failing , i am not fond of the original thermostat and like the idea of in line type. But i have a few questions-- the original thermostat has a lower plunger i will call it that diverts water flow as it opens and closes, this will no longer function in an in hose type thermostat, WILL THIS BE A FUTURE PROBLEM ?? i know many have done this with success but i am a little concerned or am i being paranoid?
I remember the in hose thermostat used mainly by the french , RENAULT, they just slid into the hose and you put a hose clamp around the hose to clamp down on the thermostat so it would not move. I think this would be easier and cleaner and cheaper than buying the housing type. Look up 1983-1986 renault alliance, you will see what i am talking about i do not know if those will fit our hoses, may have to find another type if this will not fit.
Is this a good idea?? What does everyone think? Thanks for the input

search for inline thermostat in the crd forum you'll find what we have been doing recently.

Striper: is this the t-stat housing and the appropoe t-stat that everyone is using?

yes it is. I put it in my CRD Sunday

Make sure you drill the 1/8" hole in the tstat

has anyone tried the stant #13519

I think that the first attempt at an inline thermostat had some temp spikes until they drilled the 1/8" hole - and it doesn't look like you can drill a hole in the Stant.

it says it has a bypass, if i recall corectly there is a hole with like a loose rivet dangling as the by pass.

I don't recall specifically seeing a Stant bypass but I have seen some tstats with what you describe; a small hole with like a little toggle of metal dangling in the hole - no clue why the toggle. Working solely from memory I don't recall that setup being capable of passing much fluid but it's certainly better than nothing. If you really want to try the Stant, as opposed to a more "standard" looking tstat where there is an obvious skirt (Note I've seen the hole with a toggle in these too from time to time), go ahead. If you see a bit of a temp spike on warm up (e.g. temp gauge goes a bit above mid point before coming back down) then pull it back out and remove the toggle or drill another hole which shouldn't be too difficult.

NICE PIC!! if there is no bypass hole i do not see why it cannot be drilled.

so...who is going to be the guinea pig?

i would assume it would work the same as the thermostat with the housing, maybe better since the bulb can be placed closer to the original therostat . I will try it on mine but i want to be certain my original one is fully stuck open, i may have to wait a little more.

yes, it's diesel - I don't know that they ever fail completely open (e.g. bypass closed) as opposed to opening progressively earlier up to a point. You might PM kapalczynski for an opinion as he has been inside a bunch of tstats in various conditions as part of his retrofit project.

I've got 22k on my inline with no hole drilled, no spikes, no drama and a nice toasty cabin. There is no need to over think it, use the KISS method.

When I fisrt noticed mine fail back in Jan it was at 12 o'clock -1 tick and I only really noticed it beacause I'm pretty anal about tracking mileage and noticed a 10% drop in mpg. By the time I changed it last week it had progressed to -2 ticks, but still a long way off the 1/4 mark that some have reported. My point? There are differing degrees of failure and the deterioration can be very slow. You may be waiting a long time for it to fail fully open.

I second black dog's sentiments, inline thermostat will work fine, with or without bypass hole. I welded my inline thermostat to the output of the old thermostat housing to eliminate the possible leaks from a second rubber joint. 6ooo miles trouble free, with 2000 miles pulling a 3500 pound trailer thru mountains of 6000 feet in 90 degree weather. This is an effective long term solution to our thermostat problems. Also much easier to service if new themostat goes bad.

To me the Stant 13519 is about as simple as you can get :-)r

No cutting the hose, just remove the hose at the thermostat end and insert it into the hose and put the hose back on. Could not be easier. Then it it spikes or gets too warm simply take it back out :JEEPIN:

One possible problem might be that it's rated at 195 degrees and may be a tad warm for summer :juggle:

Well I ordered the Stant 13519. So I will get it sometime next week and look it over to see if it will work. If I think it will I will install it. Then I will up date you guys.

i do know this is also available as 180 degree if needed, do not forget the extra clamp to hold it in place this is how it was used in the renaults.

Mine will also be here soon. I desperately need to do something, I'm only hitting about 145 now as I drive.
