20XE stays cold

[Iain]

If I start and drive my 20XE Nova normally it stays cold, on the dash it doesn't even leave the blue

If I rag it, it stays the same

If I leave it fast idling (2,000rpm) and it gets up to half way and the rad fan kicks in fine

I've checked the sensor isn't corroded and fitted a new thermostat and no improvement. It is cold and it's running a larger TXAutosport ally radiator but would still expect it to heat up?

are the clocks not under reading? maybe worth try a set quickly

will

Mine also use to do this aswell, its the cold air hitting the rad and coolings the water before it can get warm. Put some cardbord in offl the front the rad an it will heat up

I think the gauge is correct, as when the fan kicks in it's the same place it's always been (just over half on the gauge)

Cheers Rich that's a plan I was thinking of doing, I thought the thermostat was supposed to maintain the heat in the engine until it was ready for cooling though?

Also thought the same with the thermostat I put to thermostat's in cause I thought it was faulty. The cardbord trick works though, if you can still see the cardboard the though the grill use clear perspex. I coverd about half if my rad

My black turbo also doesn't warm up very well, only if I sit in traffic for ages. I have a tx radiator.

I got a standard GTE rad I think

dont trust the dash gauge.

it sounds fine.

i might be missing something here.... i thought keeping the engine cool was a good thing?

just take the themostat out and test it, and if thats fine then do the cardboard accross half the rad but you will probably have to take it out come summer as i had this issue with my old mk2 golf with a 2.0 16v on twin 40's then come summer it started to get a bit hot so i ended up taking it back out again
