Good point. Since I don't remember my car running particularly hot in the summer with the knackered O/E 'stat I suspect that there will not be a problem anyway.

And how many owners actually do tow loaded caravans with their CDT's?

But they won't have the in-line 'stat either will they? :confused:

Well, er - I do!

My original stat was running 10 deg cool so I had it replaced a few months ago with the original replacement.

Did you find it much runs hotter in the summer when towing? Fan on a lot?

realised the great benefit of an FBH today, mine is currently disconnected to try and isolate an electrical problem i have.

On the journey into work this morning ( about 40 minutes ) car took a lot longer to warm up, the OBD was showing about 65 by the time i got to the
M54 whereas it is normally over 70 by then, stayed at 75 for a long time before rising to 80/81 just before i left the M54, it is usually on 80 as soon as i have a couple of M54 miles under my belt rising to 85/87 by the time i get off.

Fitted mine, took about an hour... wasn't as hard as I thought it'd be (although i did end up getting a bit too much coolant in my mouth!)

Did you have your cabin heater blasting away? That takes a lot of heat out of the cooling system.

:rofl: Now that's quite funny !

Received mine last Saturday from specialist components, and had it fitted today.

I only drove 7 miles back on restricted roads and with the heater on. Dash read out showed a max of 75c and lowest 62c.

Temperature outside was - 1c, and I did have the heater on in the car, (set at Hi) because I'd forgotten what a heater was, and the luxury was intoxicating!

I suppose in this bitter weather it's better to avoid frost-bite and to hell with fuel efficiency.

I'm afraid all the technical stats are over my head? I reckon in time they'll be a majority decision on hole or no hole, width of hole if pertinent, best way to plug a hole if no hole, and on the whole it's all been worth it on the hole, or no hole ...

is that the whole picture though Martin ?

stay warm and prosper
