Diesel thermostat definative answer

[wuzerk]

I am not a 100% sure but think that the ones I used,(stainless from Halfords), were marked 38-51mm. 38mm is certainly too small for the
1 1/2" end.

I have just read through this entire thread - need a shave now !

The benefits of fitting this in line stat so far seem to be warmer cabins and better mpg, but there is another reason for those of us with an FBH, my stat setles at 73-75 which is not quite warm enough to put the FBH into idle mode so my FBH is still on even after a long journey until i cut the ignition.

I will be ordering one later cant decide whether to go USA or UK, normally that woudnt be an issue UK every time, but not sure if i would be waiting for a second batch to be paid for or now that the initial order is in place will they just manufacture a few more ?

I have checked out the USA website and the housing part number WN0073 is not shown in the options although it doesnt mean that they dont do them of course

This seems a worthwhile mod for those with thermostat problems but has anyone thought of using a Renault in hose stat?.It seems to be a common mod on Vauxhalls to avoid removing the cam belt when the thermostat packs up.
My thermostat seems marginal at present as its running at 80 to 83c and if it gets worse im going to try an 88c Renault 5 thermostat in the top hose.

TREBOR. The USA stat is readily available with a 1 1/2" inlet and a 1 1/4" outlet but that was only after i asked the supplier if that was possible because I found that that was the size needed for our cars. He has given the part number but has not posted it on his web site yet. He might not bother since he wouldn't give a discount to Jules for a bulk order so has not sold half as many as he could have done.

Sounds worth a go if it is the right size for the Rover top hose. Stuff it in (the correct way round!) and see.

Cheap as chips on ebay but there are several versions - 83°C, 87°C and this one at 89°C. Someone ought to try that as £12 with a jubilee clip is peanuts and a quick fix if it works.

I don't think you are marginal - I'd have thought that is going to be about the best you'll get in this weather with a standard thermostat.

Not only available but to show that it existed I deliberately pictured the box with the part number on earlier in the thread.

Again.....

decided to go with the UK specialist components, i e mailed them tonight to find out if i could be added to the first batch and they got back to me almost straight away and said yes and that they would be sending them out next Monday, so i will get it quicker

paulf, why don't you ask britishtrident which forum they think '...in particular has a lot of dubious information on it', eh?

Someone needs to do some measuring up.

The (pattern?) Renault 'stat listed here suggests it is 40mm in diameter. wuzerk has identified that the Rover top hose tapers from @1½" (38mm) internal diameter, and my Meziere housing was not hard to fit where I cut it, so the Renault 'stat might well be able to be persuaded to fit.

Doesn't look like the Renault stat would fit.
As usual French parts are awkwardly different

The USA stat housings do look prettier/smoother IMO than the British design
