Honda CR-V 2007 - Slow to heat up - easypeasy

Hi folks. I’ve had this crv for a few months now,and I’m very happy with it,apart from one thing. The heater in this Honda seems to take ages to get the warm air flowing. I’ve had loads of cars older than this,and they never seemed to be an issue. Is there anything I should check,or is it just a slow heater upper?! Cheers

Is the engine slow to reach temperature? Possible thermostat issue? Also some of these older Crv models have a mechanical cable operated heater control valve in the engine bay , make sure it’s opening fully .

If it's the 2.2 diesel, yes they do take time to heat up, our 2.2 in the Civic would take 3-4 miles to get up to full temperature this time of year. If it's a petrol, it should take about half of that distance.

Because diesels are more efficient than petrols, less waste heat is produced - it's this waste heat that's used to warm the cabin - in cold weather, in congested road conditions a diesel may never heat up fully.

Yet our old L200 2.5 litre diesel only takes about 2 miles to warm up!

Indirect injection and a massive egr cooler extracting heat from the exhaust gas.

In my experience a smallish diesel engine takes about 3 times as long to warm up as a corresponding petrol engine - maybe 6 miles. In winter the car can stay chilly for quite a while.

I have a 2008 2.2 CRV CDTI and it takes about 2 to 3 miles of driving in stop start 30 mph traffic for the temperature gauge to register the first segment and for luke warm air to start coming out the vents. My S-Max diesel puts out warm air after about a mile

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
