All,
I have fitted a new Euro Car Parts thermostat 4 weeks ago and a water temp sender from GSF about 8/9 months back.
My car will (after a fair few miles in this cold weather) hit the middle fo the gauge 90 degrees, however after a while it will drop (quite rapidly)
to 60 or 70 degrees. Then it might decide to shoot back up, stay the same or climb and fluctuate around.
I am worried I have a mega mega serious issue such as water pump, but convinced that surely that would cause HOT temperature readings, not drops!
It is not moving a smidge over the 90 degrees either (which is good)
These issues are happening regardless of speed, from doing 80 mph on the M23, to stuck in a traffic jam.
I spoke to GSF who are sending me a second temp sender which is great, didnt even ask lol.
I did loose a lot of water doing the stat, but replaced, perhaps I need further work on burping the water, but I used the bleed hole and 1500 miles
later there is no drop in coolant.
Hmmmm?

my golf does exactly the same, and threads on the mk4 owners club forums all agree, the TDi just doesnt heat up fully, or that fast
my fuel economy suffers in the winter
heavy is good, heavy is reliable, and if it breaks, hit them with it

Quite recently I have heard a couple reports of similar problems occurring after changing thermostats one of which was on a petrol Astra, this makes
me think perhaps there iffy thermostats hitting the market, which wouldn't be surprising as substandard car parts are wide spread. I recently
had to change a wishbone because the ball joint was completely worn out after a years use.
Another thing that may help increase the running temperature is to increase the antifreeze concentration in the coiling system to about 60 to 66%

the rate at which it drops is rapid - alomst as quick as how your dials drop down when you turn the engine off - quick!
stats was £10er.
Kinda need to know if thats work that fast etc to have much of a effect.
