Neuspeed Fan Switch and Thermostat

[MarkS]

Evening all
My car's in need of a coolant change/thermostat replacement/radiator flush and I'm just wondering if those 2 products are worth the expense or will a generic vw thermostat suffice?
I've had a search and can't really find anything other than like one guy saying "why not buy these..." 

Also is it worth buying coolant from vw?
Cos I get discountz at Halfords so it may be a bit cheaper getting it from there?
But obviously I'd only buy it if it was good enough quality 

Cheers

I think the fan switch is different spec? 2 pin not 3 pin or somethin

I suppose me posting links would have been helpful
Sorry!

Links now in OP

It says it's 3 pin so it should work?

you can buy a 71deg stat for less i think..

71deg for summer standard for winter my boss told me

Ahh nice one 
Where'd I get  a 71deg stat from?

So that'd mean changing your coolant every 6 months?
How often are you meant to change it?

according to awesome gti:

"A 180 degree F thermostat (standard is 195F) is a must to additionally bring down engine temperature. This is the perfect part to with our low temperature fan switch, all designed to prolong engine life and smooth operation on hot days"

...so this is a lower temp stat than standard anyway, same counts for the fan switch

[MarkS]

Aye!
Just wondering if its worth getting a thermostat that operates at a lower temperature, and whether its actually beneficial?

if your engine runs hot like mine then yes (sits around 100c oil temp on the motorway, up to 108 in bad traffic), but if you have no problem with it then i dont see the point. engines burn fuel better when hotter so i would expect lower mpg with the lower temp stat and fan switch... if that makes sense!

It did have overheating problems but a replacement black temp sender seems to have sorted that!
So it might be a good idea 
Surely it couldn't have any negative effects on the engine?

i had a fiesta that had thermostat problems (ran too cool) and all the oil breathers etc got completely blocked with 'mayo' from moisture build-up and it ran like crap!

my mate Google came up with this explanation:

higher temps = best life and power due to friction and thermal losses at lower temps
