Honda Jazz Mk3 2015 - 2020 / Re: Honda Jazz Mk3 Heater on Ex-Navi
« Last post by jazzaro on Today at 01:03:28 PM »I am a new driver with first car as Honda Jazz MK3 Ex-Navi. I don't know how heaters works in Cars hence want to know how much time does it normally takes for the heater to start blowing warm air when the outside temperature is in the range of 5-10 degrees. What I noticed is, it start blowing warm air after 5-10 minutes of driving, is that normal?In full-auto mode the fan runs slowly until cooling liquid temperature reaches about 45°C, it takes 3-10 min depending on usage: driving in uphills the engine will warm quickier than downhill.
After staring the car I set the temperature to hi and climate control to auto mode, and then once after 5-10 minutes when it starts to blow the warm air I set the temperature back to 20 degrees or so. Am I doing rights here and Am I using the heating system correctly?
Also can someone please explain the mechanics behind the functioning of Heater in general.

That's what you get with our "deregulation", second class citizens with regard to recalls and recourse available of the little man to large corporations... c.f. brake simulator

and it doesn't seem to shift much air compared to other cars I've owned.
However, I tend to mostly set it to "auto" and let it do its thing. In the colder months, it waits for the heating to warm up to have something warm to circulate, therefore, you can increase the fan speed manually and eventually it will get warm enough for you to press the auto icon. I have to do this as ours suffers a lot from condensation in the winter.
Also, I find in summer I tend to increase the fan speed if I'm feeling particularly warmer than what the car's system is deciding to do, then again pop it back on auto.
It would appear most people say to leave it mostly on auto to ensure the AC system seals are lubricated.

On cars with an internal combustion engine (petrol or diesel) the engine is kept cool by circulating coolant (a mixture of water and antifreeze) around the engine and then cooling it by passing it through a radiator at the front of the car. Engines work best when hot - with the coolant at around boiling point. (Its best drive more gently until the engine has reached its operating temperature. There is normally a blue light telling you the engine is cold. Take it easy until this light goes out) ) If the air passing through the cooling radiator is cold it can take longer to warm up. There is normally a thermostat in the system that stops the coolant circulating until the engine is warm , so it heats up quicker.
For cabin heating there is a second small radiator behind the dashboard. When you switch on heating a valve is opened so some of the engine coolant passes through this heater radiator and it gets hot.When you adjust the heating level it adjusts the rate of flow of hot coolant (which may not yet be hot
)
Air is directed to the cabin and heats up as it passes through this little hot radiator. Some comes in as you drive along, or you can boost the amount of air by using the fan. You can also distribute the hot air where you need it most , such as to a frosty windscreen , or your feet or a bit of both. You may need to adjust air flow , fan speed etc to suit your needs and comfort as the car warms up.
A car with climate control can adjust heating and air distribution automatically using electronics . Or you can set things manually. Your system can also control and cool temperature automatically (or manually) by using air conditioning.
Put in very simple terms Airconditioning uses a second separate system of radiators to cool air below the ambient air temperature.
There is quite a bit to learn to have full control of heating and cooling. Its probably in the drivers handbook which you can download free from Honda as a pdf

« Last post by jasonevans on Today at 12:00:48 PM »About 5mins is normal as the engine has to get some heat into it before it opens the heater valve.
Colder temps take a bit longer.
What I normally do is set the temp to cold for about 3-4 mins first so engine gets warmer a bit quicker and then turn heating on. Seems to work better that way for me.

Honda Jazz Mk2 2008-2015 / Re: Milestone mileage reached.
« Last post by jasonevans on Today at 11:47:28 AM »I had a MK1 Jazz before and sold it to a friend. The car has currently just ticked over 201k and so far all it's needed are normal wear and tear items and a clutch at 165k.
Reguler oil changes are the key to keeping these cars going I think.

That said, I know these things can annoy once you've noticed them. Maybe replace with a cheap used part? Ebay would be my choice for searching.

Honda Jazz Mk2 2008-2015 / Milestone mileage reached.
« Last post by Westy36 on Today at 11:42:07 AM »Our loyal little Jazz hit 144,444 miles the other day. 
The car has never broken down, only ever needed servicing and still runs really well using no oil between services. Brilliant little motors.
Next stop, 150k! I've total confidence he'll fly past that milestone.

Honda Jazz Mk1 2002-2008 / Re: Whats difference between ls, s and se models?
« Last post by Westy36 on Today at 11:30:47 AM »Your car has fog lamps in the lower bumper. On the MK2 Jazz in the UK, only the posh models got those so I'm guessing you've got the SE? Sport models come with side skirts IIRC. You could phone your local dealer with the VIN number and ask them?
