Important! : Engine Overheating

3rd August 2009, 16:09

Just finished my VTS conversion on my Furio...

Everything seems to be working fine apart from the temperature...

Went on like a 5 min drive and the temp went all the way to the top (red light came on)

Got it home and the water level was down low (even though it was at the top before I left)... Waited for the engine to cool down and filled back up with water.. Waited a bit longer and level had dropped again so filled back up...

Now i've just started it up and left on idol, and after less than a minute, fan is on and temperature is wayy above 3/4 nearly the full way up...

What could it be? It's the only issue i've got and I want to be out driving it!!

Cheers,
James.

VTS rad mate, and yeah was bled properly

Could it be the waterpump? Fan kicks in fine, but temp still goes up..

3rd August 2009, 16:23

could be the thermostat sticking. beyond that im not too sure

3rd August 2009, 16:40

New thermostat? Happend on my Corsa, know there not the same but there cheap enough to replace anyway.

3rd August 2009, 16:48

I've just disconnected the top radiator hose and turned the enigne on and there is no water coming out of this with it being disconnected...

Surely this means that the waterpump has gone? Is this involved/pricey to replace?

3rd August 2009, 17:00

i think it involves taking the cambelt off.....

Just put a brand new belt on lol..

I just don't know what it could be.. I'm thinking waterpump but maybe thermostat or anything else.. Don't really know tbh..

3rd August 2009, 17:11

replace the water pump & thermostat and go from there mate.

Yeah looks like that's what ima have to do mate..

Are these pricey?

3rd August 2009, 17:13

just because there is no water coming from top hose when running doesnt mean the water pump has gone! water will only come out from the top hose when the thermostat is open once up to temperature, when below operating temperature coolant will simply flow round the engine so it heats up quicker

Ah cool mate. I wasn't jumping the gun, but my knowledge in this field isn't that great! There was no water coming out og the top hose when the engine was started right the way until when it got up to near full temperature (like 1-2 mins later)..

Could well be the thermostat.. where abouts is this on a vts and how can I check it??

Thanks

if the top hose is disconnected and no water is coming out with the temp guage at the top it sounds like the thermostat is fucked. when its hot the thermostat should open to let water into the rad to cool down

Sounds like you've got it spot on there tbh.. I really hope it is the thermostat and not the waterpump...

3rd August 2009, 18:32

no experience of a saxo waterpump going but i would have thought if that was fucked it would be leaking

4th August 2009, 16:10

Update

Took the thermostat out and left the top hose disconnected, turned the engine on, revved it and water came out which to me suggests the waterpump is fine?! Then bought a new thermostat, fitted it and started her up. Seemed fine, took ages to go up to half way, but when it reached half way, it rocketed up to the top. I turned it off just before the red light came on..

In my eyes, this eliminates thermostat and waterpump...

What other things could it be? Booked it into a garage tomorrow morning..

Cheers.

hope you get it sorted. you must be itching to get a good run in her

Cheers dude, yeah i'm devastated. Never heard a car sound so good on idol or when revving.. Supersprint full system is the bollocks! Really had my hopes up a min ago as it took ages to reach half way so thought that replacing the thermostat had sorted it, but clearly not

4th August 2009, 17:12

Anyone suggest what else it could be?

You have released all air in the system right? And got enough water?

I have a simular problem. When is it going in the garage? Will you tell us what the problem was once its been in?

Thanks

Yep, seems all air blocks etc have gone and the water was filled right up when I started her up. I'm 90% sure it's not the waterpump and 100% sure it's not the thermostat as replaced this today...

Going in the garage at 8am tomorrow.. Been without a car for over a week now and i'm so eager to drive it with 16 valves!

I shall let you know the problem!

4th August 2009, 23:47

Another thing I noticed, was when I turned the ignition key, but didn't start the engine, the light that goes red when the temperature gets too high (by the temp gauge), came on for a split second and went off. It does this everytime I turn the ignition key just a quick on off...

I was just thinking that this might be like a way of identifying the problem? As I've never noticed this before...

4th August 2009, 23:47

blockage??? This is a hard noe tbh mate! Maybe Ur temp sensor is just fucked. Try changing that.

Can't see a blockage and the water seems to be pumping around fine as when I disconnected the top hose and revved the engine, water splashed out which would suggest that the waterpump is working fine and that the thermostat is working fine as it would have opened! Don't think it's the sensor tbh, the engine just goes red hot!

The experts will be looking at it tomorrow! Fingers crossed it's a cheap, easy fix, as after the parts for the conversion, I really don't have spare cash for things like this! And I need my car asap!!

5th August 2009, 00:47

Good luck with it mate and let me know what it was in the end lol you have eliminated the obv i dont see anything really major what it would be lol.

5th August 2009, 00:51

tried running it without the stat?

5th August 2009, 00:54

you should have run it without a thermostat for a while, if it was still overheating without a thermostat but water was flowing then you can illiminate thermostat and pump but then have to look at why it is overheating ie is it boiling water off? Is it burning oil etc. And btw if the thermostat had been buggered and stuck shut you wouldnt have been able to bleed the coolant system properly as some parts of the system wouldnt have had flowing coolant.

5th August 2009, 00:56

what bottom hose you using?

if your still using your fruio one, which is longer than the vts one, and with the longer rad, you could of kinked the hose.

unlikey, as im runing a vts rad with vtr hose, but you never know.

Update..........

Right guys. It was booked in at Citroen for them to have a look at it this morning. Drove down there, got pretty close and it went the full way up and the red light came on.. Carried on driving for a bit and it started to go down.. Parked up at Citroen (before they opened) and let it cool down, went for a drive around an industrial estate and the temp went to around 3/4 and stayed there! Cancelled the appointment at Citroen after speaking to a bloke there... Have been driving it literally all day, done a good 50-60 miles ish, various roads and motorways. It seems to stay at 1/2 way on motorways ie when more air is coming in but doesn't go below half way. When driving on normal roads and in traffic it creeps up to around 3/4 and usually stays there, it did go up slightly higher once but didn't go all the way to the top at all...

Does this mean problem solved and maybe there was just an air blockage and it needed a bit of a drive to get rid of it? I'm still not that happy with it sitting on 3/4 though tbh, even though alot of people on here say that there vts' run pretty hot...

Sorry for the esssssssay!!

Problem solved then.

I do hope so lol

check the heater matrix isn't leaking. mine ran low on water and got air in which took me ages to get out. the air pressure can burst the matrix. mine was leaking from the ducts that blow air at your feet.

If there is no water coming out the top hose then the thermostat isnt working properly as that lets water pass to the radiator at a certain temp to cool it down.

6th August 2009, 19:38

sound to me that you need to bleed the water system up!!

open the bleed points to make sure that the flow is there? need need to fill the rad up before up started the engine!

to bleed it up first fill the rad up, open the bleed point on the top of the rad! above the top nose, before starting engine! make sure that you see the coolent pass though there, that means the coolent is passing though the rad to the top hose!

then start the engine watching the coolent level topping up when the coolent level drops as it will as it goes though the engine!

open the second bleed point next to inlet on the left hand side!

make sure that coolent is passing though there then just keep topping up the level til it stop going down and get up to temp make sure the fan kicks it!!

job done!

6th August 2009, 19:43

sounds like some typ eof air blockage or thermostat not working good, happend to mine and it was a faulty radiator :] (mine was a standard 1.1 engine though)

6th August 2009, 19:47

need bleeding more! by going on what he saying i am 99% sure that hour problem!
