Default How long should the engine take to warm up?

I'm not talking warm enough to thrash it, but how long under normal driving should it take to reach say 87c?

Mine seem to take forever and I'm thinking of using some sort of valve to block the heater matrix until it reaches a certain temp.

Any other ideas on how I can get it to normal temp faster?

Cheers,

Wayne.

Mine takes about 10 minutes.

If I just leave mine to idle it'd take 20-30 mins to get to operating temp & then the fans would kick in. No need to make a valve as you already have one: it's the cold/hot temp control in the cabin. Turn as far as you can on cold, this should help warm up quicker.

(if it takes longer than 20 mins then I'd check the thermostat is not stuck open)

usually a good 10 - 15 minutes before temp is at 80 which is safe for you to get the revs nearer the red

the radaitor fan kicks in at 96 degrees and usually takes the temp back to around 87.

Interesting as you are using LPG, maybe the burn characteristic is the reason. My Subaru is at temp on the standard temp guage in no time at all (maybe 1 mile down the road), whereas my work HDi Berlingo takes several miles to get up to temp (and absolutely ages if it's just left idling on the drive, where the Subaru would still be up to temp in under 5 mins). All the diesels I've driven have taken much longer to get up to temp than the petrol vehicles.
Is it different if you run on petrol only?

Oil or water.

Water not that long, 5-10 mins idling, oil longer. I wait until my oils up to temp before giving it heavy right foot acceleration.

Depends on what your doing, can take 10+ miles or 5 miles in stationary traffic, if you want to know then the best thing to do is buy an oil pressure/temp gauge but dont go by the water temp, water will get hotter considerably quicker than oil will, and in winter it can take even longer for the oil to heat up.
As for the diesel thing, most still have iron lumps in there, iron is a little less conductive than alloy for heat, hence it takes longer to heat the oil up

ok, just to clarify its purely water temp that I am interested in and how I can get that to be hotter, faster.

Cheers,

Wayne.

The car starts on petrol and WHEN up to temp it switches over to gas. So, the quicker it warms up the better.
