mg zs diesel heater ?

[roverdave81]

Rite every1 ive noticed since ive owned my zs diesel that it take 3times long for the engine to warm up so the heater blow cold air out 4 ages where my 180 would be blowing warm air out within a couple of mins is there away that can sort this or is it just the down side to owning a diesel in the cold weather

Yeh, mines the same and even once its warm its like an asthamatic blowing through a straw.

Diesel engines take longer to warm up than petrol engines, it's the same with all of them.

Yep, does take a few miles to heat up, but then its OK.

Yep same here.

So im told you can use a different thermostat and it heats up much quicker.

We had a 25 diesel and it was the same - good heat when hot though but crap A/C.

Probably not wise, thermostats are rated for the place a car is made. IE you should use a different rated thermo in a hotter / colder country etc (not sure if Rover actually stuck to this principle though)

I'd stick with what was originally fitted.

thermostat isnt going to make any difference as its closed when its cold anyways, the whole point of a thermostat is for the engine to heat up as quickly as possible as its closing off the radiator flow, by the time it get to 70-80 degrees when it opens itll be already blowing warm air anyways

Could be worth trying something like this:

are your EGR valves working properly? i have plugged all mine back in for the winter as it was just taking too long to heat up, with out the EGR connected then it would take about 5-6mile to warm up, with it connected then it only takes about 3 mile to warm up now, as soon as the weather warms up again then it will get disonnected again
