Hi everyone

I wander, how quick warm air starts coming from vents? I'm driving W220 S320 petrol(gas). Here in UK temperature is going down and every morning when i start driving cold car warm air starts coming from vents after few miles. My wife's SEAT 1.4 engine starts blowing warm air after half mile.
This summer i replaced radiator (it was leaking), coolant (MB) and thermostat for my W220. Air con is off. Engine temperature is normal around 90 celsius. Could be a Duo-valve issues? My climate unit do not show any faulty codes.
Thanks

your lpg system takes the water supply for the heating of the vaporiser. so its connected to your heating pipes. thats why it takes longer.

Your vaporizer will be covered in frost on cold mornings upon starting the car.

Thanks for replays :)
I understand that extra pipes and it will take longer to warm up. My car always starts on petrol and when engine temperature reaches 50 degrees Celsius, then all gas system switches on. This morning i started car, left running for 5-10 min and then started driving. After half mile engine temperature was 60 degrees Celsius, heater was on max temperature and blower was on position 4 out of 7, but air from wents was just warm. When i drive long distances inside the car gets warm/hot. What about your cars guys? When your car engine temperature is around 60 degrees, will your heaters stars blowing warm enuf or hot air?
Thanks

mine never shows 60. I sometimes think that even 78-80 is too low on my car. but thats that i have while cruising. constant 80. I switched the heater on today and the reading was 78-80.

if yours always 60 you might have a thermostat stuck open...I would guess. how long does it take for your car to reach 60? 5minutes? 10 minutes?

have you got any pics of the engine with the LPG installed? just out of interest.
oh, and say you fill up with £30-£35 of LPG, how many miles you would do on that amount?

As you can see that red bit that is LPG switch and further deep vaporizer is hidden.

That switch is inside car and i can switch between LPG and petrol if LPG tank empty.

Hi.

Good pics sauliusagintas.
Im thinking of the conversion.
With prices heading up to the £1.40 mark and an 88 litre tank I think I will defo get it done sooner rather than later.

Can you answer a few questions?

Have you had any issues with the LPG conversion?

Power etc still the same?

What size of tank did you go for?

And what is the range of the tank?

Thanks very much in advance. :thumbsup:

Hi,
I've got more issues with rust than with Lpg. I'm averaging 20 Mpg combined on lpg (for what i pay is around 40 mpg).
Car starts on petrol and then switch on lpg, so you need some fuel anyway. My tank is 50 Litres and im could do 200 miles combined and few extra on motorway. Power, you won't notice diference until automaticly system switches to petrol. Then you feel that few more horses wake up :) I;ve got frend who does Lpg conversions.
Any questions, just ask.
Best regards.
