fitted inline thermo

Rocket Man · 4th December 2013, 19:14

I fitted an inline thermo housing in the top rad pipe today. I found that it took forever(20mins!) on an in-town drive to reach half but then would fluctuate down again.

On a motorway run it sits bang on half.

Is this fluctuation in town due to location of thermo?

The new stat is either leaking or opening too early.

I fitted a circoli inline stat last winter and saw almost no difference with to without. On figuring out how to get the diagnostic mode in place it was clear that the car still - albeit only slightly - running cold. I have just fitted a stat from DMGRS and it seems significantly better, albeit only on a short test drive, but I'd not seen 87 before.

Get the display into diagnostic mode, but I think you'll find as I did that your stats are both leaky. The one from DMGRS is obviously of much better quality.

I have to say, I have noticed with the ones I sell I've noticed temperature does seem to hold well - I've used other brands in the past on my 75s and noticed some don't perform as well.
The Gates item I fitted on my first 75 seemed to hold well, but the item I had from ECP a while ago (not sure of the brand) did take longer to warm up and didn't hold it quite as high. All were 89 degree items to my knowledge.

I went for this thing:

wondering if the thermo inside it is faulty

I tried two of the circoli ones from ECP and found them useless. Never above 83 and fluctuated. In the end plumped up £100 for a genuine one fitted. Well worth it.Sits at 87c.

i was just hoping to get over the winter with a simple fix and do it properly when better weather comes.

I fitted one of these well over 12 months ago and all was fine to start with but then the temp via OBD was falling, so i replaced it with a 92 degree stat in the housing and it has made a big difference.

Temp now gets to between 100 and 103 before falling to 89 and then cycling again, warm up time is much better and cabin is toasty !

I had never seen the temp in the 90s before, let alone reaching 3 figures, but the temp gauge still doesnt budge from 9 o'clock

I also fitted the inline thermostat, but found the temp gauge never went passed 7.30 apart from under load on the motorway. As soon as the load came off, the temp would drop and so would the MPG 34mpg!!!!! Rubbish.
So i have also replaced the standard thermostat!! so effectively running both, the motor heats up quickly in comparison and the gauge remains at the 9 O’clock position without fluctuation!!!

The most impressive part of all this was 51.3MPG on a very steady run home, 50mph for the most part.

Hi trebor,

which 92 degree stat. did you fit as its giving better figures than my 88 one which came with the Specialist Components Housing.

Cheers, Pete.

Trebor where did you get the stat from i have fitted 1 of these and the first stat that came with the fitting just didnt work (leaking past) and the replacement now has started leaking past as well
