YES when its frosty you should start the engine at least 3 to 4 minutes before driving as,, as you drive all you are doing is driving towards the cold air and the radiator dosent get a chance to get warm so the temp will never reach its 90 so warm it up first and when the heaters warm or hot then so you will be...
AS you work better when warmer (yes) so dose your car

I have a 2005 Santa Fe - the problem is that the temperature gauge is always at the half way mark but the vehicle's hood becomes very hot after driving for just about 30km

It's perfectly normal for the hood to get hot to the touch because of the extreme heat being generated by the engine. Not too many years ago, the car manufacturers would put insulation on the underside of the hood. This would keep the hood cool, and also quieten engine noise. I'm sure some premium priced automobiles still have this luxury.

Sounds like your thermostat is bad or at least sticking. Replacing it is faily simple and even the good ones are less than 20 bucks. Hope this helps! (rate if useful)

Ive a 1995 Lexus gs300. Its been running fine until today. It has been extremely Cold, and today One of the Hoses Blew off the car obviously water and steam. The hose was fixed by the AA, and on my way...

Trust what the AA says ..

It does sound like you have an airlock .. and the airlock is likely to be in the heater matrix, as opposed to the radiator.

Bleed the heating system: Set your heater controls to hot and fully open. Let the engine work until it reaches normal operating temperature. Check your coolant level to see if it has dropped.

You can always bleed the coolant system by leaving the coolant bottle cap off for 10 minutes whilst the engine ticks over.

It isn't your water pump.

if overheats,and trows water or steam,there you can think on the water pump or the thermostat,but you only have a signal problem,try replacing the tempeture sensor.

Heat gauge

Before getting too upset about this, try changing the temperature sender. Can't tell you where it is but it is usually on or near the thermostat housing but some engines have it on the intake manifold or rear of cyl head.
