General Cold weather warm up

[multiplex]

I have a 04 JTD and have noticed over the last few weeks that it takes much longer to warm up. Yes the weather is colder, but it always seems to take quite a time for the engine (and heater) to get to a reasonable temp. I only get 2 bars on the temp readout at best at the moment.
Just wondered if this is typical for other Multis in this cold weather, or maybe my thermostat is stuck open and not letting the coolant get up to temp.

Faairly typical for the JTD derivatives.

Turbo diesels of all makes are well known for taking a considerable time to warm up sufficiently to allow the interior heater to come in effectively.

In some markets where particularly cold weather is usual an independent petrol or diesel powered interior heater can be specified. Not here though. It's not cold enough...

I was thinking about covering half the rad with foil or cardboard? Would that work?

no don't do that, buy a 12v heater

Too late, I've wrapped some clear signwriters vinyl over the front grill area covering 70% and then I'm going out for a run, I'll let you guys know!

Didn't get above 2 bars on the swingometer yesterday, I'll see what happens. (New head coming up!)

hi, i have just spent £60 on a new thermostat hose clips and antifreeze , it has made no difference at all. my multi still runs cool in this weather. I left it running for 45minutes after, and the top hose was still cool . by the way its a 2000 jtd. can only asume thats how they are .

as the poster above says, turbo diesels in general take alot longer to warm up than petrol equivalents as they are a cooler running engine.

most cars in colder climates have a webasto heater or similar.

Well not bad, got three bars up, much better than before, I'll post up a pick.

Toasty hot coming out of the vents.

I am certainly gonna try this, as all else has failed , and I am freezing to death in the multipla.

Looking at the gaps between the grill I reckon some of that grey plumbing pipe insulation cut to length would fit really snug in there, buy a length and then add or remove as necessary !

Can you email some over to me?

its on its way,,,, Merry christmas

I just shot over to Travis Perkins to get some, the bas***s were shut!

Hi Multipla owner.

Calling here from Denmark. Merry christmas,i have just a week ago mounted a used webasto diesel heater in my 2005 multi 1,9 jtd because i also have this non heating problem, last night it was minus 15 degrees turn on my webasto half an hour later the engine was 64 degrees.So i will say that it is nessesary with this extra heater.

I would like to wisch all a happy new year.

Hiya Tommyk,

I've used an Eberspächer D4 for years in my garage / woodshop. I hope you mean you mounted the Webasto under the Multipla rear seats and not in the engine compartment.

Very prevelant topic this in the recent winter weather. I have a recently purchased a Panda Cross 1.3 multi jet diesel and noticed that it takes a fair while to warm up.
My research indicates that it is a common problem with modern deisel engines (read somewhere a detailed reason for it but couldn't then find the web site again!). One thing that I do remember is that the cooling system on modern vehicles has to be able to cater for where ever that vehilce may be exported to and so the cooling system may possibly be able to cool an engine twice the size that it is fitted to!
As per most internal combustion systems the coolant circulates only the engine block until reaching a certain temperature and then the cooling system thermostat opens allowing the radiator and associated pipework to introduce a larger volume of water to the system. Bear in mind that this additional water is cooled via the radiator which in recent weather conditions has been subjected to waaay below freezing conditions and so the enigine coolant temp gets dragged down straight away. In my youth (don't ask!) many vehicles could be seen with adjustable radiator blinds over the front grill, some automatically or remotely controlable once engine temp reached normal. perhaps it's time for them to be produced again?
On a similar line I have recently fitted a 240v/150 watt engine oil sump heater to my Panda - controlled by a timer in the house warms up the oil a couple of hours before I go out. Still under review at the moment.

Hi QinteQ

I have build the webasto in the enginecoolant system,the hot water from webasto going direktly to the radiator in car and then back to the engine for heating this up,so yes the webasto is placed in the engine comparment,is this a problem known by you,i would like to know.So far it works for me, in the next few days i will have the webasto to turn the cabine fan on so i can heat the cabine up without starting the car.For a comment i will tell i am a mecanic.
Best regards.Tommyk.
