Temp doesn't go above 80 DegC (320 CDi)

[mr. shr]

I assume I6 = straight six??

For my car (2004 E320 CDi):-

Thermostat: A6462000015
Temp guage sender unit: A0009050700

I would guess same is true for yours?
I in doubt, PM me your VIN and I'll check for you.

Thanks, Mr Shr. That sounds like the one.

I have to go past the local stealer tomorrow so I will drop in and pick one up. Wish me luck for the weekend! (In a thermostat sense only, of course... )

 

[mr. shr]

If you can, try and take pics for the benefit of no hopers like me.
I see a 'How To' coming along!!

 

[corned]

I'll see what I can do. I just hope it doesn't turn into a 'How not to...'.

 

[mr. shr]

I just hope it doesn't turn into a 'How not to...'.

Well, oddly enough, one of those would be useful too!!


Good luck and keep us posted.

OK - the job is just getting started.

I purchased the thermostat from Inchcape Nottingham this morning at £44.84 all in. I note that the new 'stat - part number is indeed A6462000015 - includes the gasket plus a new sender already circlipped in place.

The engine is still a bit warm yet, and I can't get the oil filter cover undone - how bloody tight is it supposed to be? I might leave it until tomorrow morning so as to ensure everything is as cold as it can get. We'll see.

 

[corned]

I have done the sensible thing and given up.

The oil filter cover won't budge. I can't move it by hand, and it still won't move even after getting a bench vice in on it.

When you're me, you learn to get used to these things happening to you. I'm going for a lie down.

Anyone got any good ideas for removing it? Semtex? Big blunt screwdriver rammed right through it, like the old technique for removing stubborn oil filter cans?

I give up! Surely it's not supposed to be that tight?

 

[p1nny]

should only be hand tight!you got a big set of stetsons you can get on it for leverage?

 

[corned]

That's what I thought! Did you mean Stilson's? I have got a set, but not big enough to get round that.

I thought the vice would be serious overkill, but no - no matter how tight I clamped it on, it slipped round to the next facet on the cover without moving it.

I assume the pros have a special tool wrench specifically for this. Unfortunately I don't!

Maybe I need to stick to plan B and have a crack at it in the morning when it will be cold.

 

[corned]

Maybe persistence pays after all.

Job done!

I'm just going to take her for a spin around the block, and then I'll write up that 'How to'.

It took the bench vice plus a hammer to free that damned oil filter cover.

 

[mr. shr]

Nice one.
Glad you got it sorted.

Look forward to the 'how to' although I don't have a bench vice!!!

Let us know if the change gives better fuel ecomony.

How to:

This is the way to do it.

I hope this is useful to everyone contemplating doing this job themselves.

The test run proved very interesting. The gauge quickly rose to 85C (Never done that before!) and stayed there as steady as a rock; in town driving, a quick blat along a long dual carriageway, and a slow crawl back again.

I'm well chuffed! I will post after a good long run tomorrow to let you know how the mpg is fairing.

Beer - I need beer!!

When mine was replaced last year it went to 87-88 ( from below 60) and stays there rigidly through all weathers. Better MPG as well.

 

[corned]

With the 211, the temp gauge is a line of LCD bars. It appears that there is a bar for every 5C from 40C to 120C.

 

[renault12ts]

I have auto climate control. If I hold in the rest button, the display changes and gives lots of additional data, including a digital read out of the engine temp.

Economy

Following a good run yesterday, I can report that the fuel efficiency has definitely increased, and quite noticeably too.

We have been doing a regular run up to Sheffield in recent weeks (every Saturday) and I have always put the cruise on 70mph and let the car drive there itself.

Recently, I have averaged about 35-36mpg on this run with the temp gauge on 70C.

Yesterday I did 42mpg with the temp gauge on 85C, which is definitely back to normal.

The gearbox shifts seem smoother to me now too, but I can't explain why that might be, so I am putting it down to 'placebo effect'.

I did my thermostat today. It cost £22 from eurocarparts, branded the same as the original on that I removed.

Total job was 15mins,

Removed Engine cover, used a e10 torx to remove the 2 bolts that secured the housing, removed housing and replaced with the new one, refitted the coolant pipe and refilled with antifreeze mix, refitted engine cover.

I lost just under 3 liters.

 

[mr. shr]

How do you quantify how much coolant is lost?
Do you catch it in a bowl or something and can you just pour it back in when the job is finished?
Or do you need to top up with fresh stuff?

 

[corned]

I think you have two options on this.

Option 1 is to remove the undertrays and release some coolant (a couple of litres or so) from one of the drain taps into a suitable receptacle. I think from reading here before that there is one on the engine block and one around the radiator somewhere? Don't quote me on that however.

Option 2 is the lazy way (mine) where you just let it go and forget about it.

I reckon that I lost around 1 to 1.5 litres. The best way if you're not sure is to buy a 5 litre concentrate can and you can make up to 10 litres of coolant or thereabouts from that. Then it doesn't matter how much you lose!

 

[markmifsud]

as Corned, I just let it go, and had the antifreeze already diluted to 50%. and topped it up to the correct level
