Cool heater in the cold weather
Discussion
This is my first winter with the tvr so I may be expecting too much but my heater is very cool when moving.
It warms up nicely when I get to some traffic lights but anytime on the move, it's cool. It certainly made the roof off driving today less pleasant than normal.
I know the temp gauges on these are renowned to be useless but on the move (single A roads) it is reading about 60 degrees, sometimes lower. The same driving in the summer was 75/80 ish degrees. When I get to traffic lights and I feel warmth coming from the heater, the temp gauge has moved to circa 70 degrees as the car isn't moving in the cold air.
Reading the forum it looks like the heater does cool a bit on the move but they are still normally effective. Likewise 60 on the move seems too low.
What is the best way to check if the thermostat is stuck open without actually taking it out?
Any other thoughts most welcome.
(PS - I don't suspect an air leak or the heater valve as the heater does get hot when the car isn't moving)

Just started her from cold and then held the top hose to see if it got warm very fast (as in thermostat just opening) or warmed up gently (as in thermostat stuck open).
Hose warmed up gently and even when it was warm, water temp gauge still hadn't moved from bottom.
Looks like my thermostat is stuck open.

I'm replacing my thermostat this weekend and can somebody give me a heads up on how long to do and what involved?
I've just read a piece that suggested removing the dizzy and removing the serp belt. Is all that really necessary?
I was just hoping to remove dizzy cap and that would be enough room (or am I deluding myself?)
Thanks.
