hi Nikki, Autostyle is a large accessories dealer in Jhb & Durban. They do mail orders as well. They also stock a temp gauge that has external temp sensor that is mounted to the outside of the engine block or radiator. Their website is: www.autostyle.co.za. They stock the pod in 1; 2 or 3 gauge sizes. The 3 size will fit on the middle flat section on top of the dashboard 2" gauges regards Spikes

i use VDO gauges, but i'm not happy with them. They don't seem very accurate at all times. i plan to replace them with stack gauges. www.stackltd.com/

;)That is what happens to you if you drive under the influence of alcohol. In Belgium the traffic authorities remove your steering wheel and place it on the left so that you passenger can drive ;D Wonder what Jan does if he has no passenger to drive him around

Hi Nikki
What I did with mine was the remove one of the radiator hoses and put the probe into the hose and refit the hose. I put some gasket maker there the wire of the probe sits under the hose. Tightened the clamp and re-tightened when hot. No leaks and I have a accurate reading. Will look for a pic just now.

Hi Calla Did you put the sensor into the pipe from the thermostat to the engine?

Yes. The middle one on the thermostat.

Thank you for the info guys - I really appreciate it as always! I've been looking at the websites suggested and I'll probably be back with more questions when I've had time to study and understand them more. NIKKI

Hi Guys
A few weeks ago I took Nikita to the Radiator people to get her radiator checked and had the overflow bottle and the red plastic pipe replaced at the same time. When I got home I noticed leaks from both ends of the red pipe. Coolant also seems to be popping out of the top of the new bottle which never happened with the old bottle.
Since then, I have been trying unsuccessfully to fix the leaks by first of all trimming the jagged edges on the new pipe so that it fits flush against the radiator and the bottle, changing the jubilee clips and tightening these after letting the pipe warm up in the sun. Last weekend it seemed fine but the one going into the radiator started leaking again yesterday.
Looking at my old bottle, which still has the old pipe attached , there seems to be a thin layer of sealant around the pipe, (mastic?) that may have stopped it leaking before. Should I be doing something like this – or trying a different type of pipe? I don’t really think I can tighten any more without breaking something! ;D

Remove the pipe and put some Loctite Shellec on the fitting before fitting the pipe.

Hi Nikki The pipe itself should be of fairly soft rubber so as to mould air tight around the hard pipe fitting on the radiator and overflow bottle Give Charles' suggestion a go if the connecting pipe is soft(ish) Spikes

Check your radiator cap, if the bottle overflows, the cap should be keeping the pressure inside the system.

Hi Nikki. I know that this is going to sound a lot like 'teaching your Grandmother to suck eggs' but.....How full is the overflow bottle when the engine is cold ? It should be only about half full to allow for the (hot) water to expand into it after the engine has been running. Regards, Keith and CERATOTH

Thank you for the assistance guys – I really appreciate it. Charles – thank you for the Loctite Shellec suggestion. Do I look for this in an Autozone type place or a hardware shop? Spikes - the replacement connecting pipe is exactly the same as the original which I would describe as a hard(ish) plastic as opposed to the soft(ish) rubber water pipes. It’s exactly the same kind of pipe as the one shown in Ari’s latest photographs but a lot clearner! ;D Ari – I changed the radiator cap at the same time I visited the Radiator guys so the bottle overflowing could be connected. I’ll put the old cap back and see happens. The new bottle may have something to do with it as well because the cap doesn’t seem to fit nicely and I may have to put the old bottle back. Keith – since I started reading this forum my bottle sits about half full when cold but when I first bought the lovely Nikita I was told by Lada Centurion that I should fill it about an inch higher for South African conditions. Thanks again guys NIKKI

Hi Nikki
Yes autozone should have it. Shellac works better than silicone on the old gaskets as it was designed for it.

Thanks Charles – I bought some today at Autozone but as there was a big sticker covering most of the instructions I couldn’t check for any heat rating and I now find that it doesn’t have any. Does this mean that what I’ve bought isn’t suitable for this particular application? Keith – when I tried changing the radiator cap this morning I also had the same problem that you mentioned earlier as one of the spares I tried wouldn’t fit either. NIKKI

No the other stuff is fine. I have just found this works better on the paper type gaskets.

Nice Lada Dewald !
Maybe she is just overheating because the cooling system has not been bled correctly ?
Is she overheating in slow traffic ?
Maybe just a faulty Thermostat ?
There are quite a number of clever guys at the forum, and I am sure they will be able to give advice .

Very unlikely to be the head gasket if you had no problems driving down. More likely dirty radiator, missing fan cowl or sticking thermostat.

Dewald asked me in pm if it's POSSIBLE the head gasket is blown. And yes, it is, because there are air bubbles in the radiator and the temp is always +- 100°C. I'm not saying that it IS blown, but it's possible. For good preserving of the cooling system at a long period of stand still, there should be coolant in the system, and not only water. With only water, the gasket will rot. dewald: pretty much dummy ;D (in Dutch) Also use the links in the text. It's a howto for the MPI Niva, but you can use it for any Niva www.ladanivabelgium.be/Techniek/cilinderkoppakking_vervangen/cilinderkoppakking_vervangen.htm

Hi Jan,
Jy is die man! Thank you for the excellent guide to replace the head gasket.
It is very hard to believe that somebody would keep a Niva in such an excellent condition and not add something to prevent rust in the cooling system! This is a perfect example why we need people like Ventz in SA - to do the basics right when they service Nivas.
Also keep in mind that even with anti-freeze in the system the cooling system may be severely damaged (even the aluminum head may be damaged). This is when the anti-freeze is left in too long; it turns into a mean acid. In fact, it is well documented that antifreeze should be changed twice a year (two seasons), but at least once a year (and not too much).
I suggest testing the cooling system after the head gasket was replaced, because it is not to say that the gasket was the only problem with the cooling system. Check the heater valve too that may have been damaged due to rust (a common Niva problem) while all the coolant is out.
I hope the above is of some help (as is the other outstanding world class cooling system information and know-how on this forum).
Regards,
Fanus

Thanks to all Will need everyone's help, will start a thread "changing head gasket for dummy's" Thanks Dewald A thread like that would save many owners a lot of money, and I am sure the guys would be more than willing to share their knowledge. Danie

Good news about the "no gasses in water" puzzled by "no circulation" can be 2 things.Very dirty blocked radiator; water pump U/S
Good luck

I think your problem is most likely the water pump - unless the car never had the proper coolant in the system.

I have heard of impellers on waterpumps comming loose and the shaft just turns but not the impeller as the resistance of the water is too high.

Remember the NIVA had been standing for a while so deposits could have formed in the aluminium radiator cyl head and block. The plastic impeller should be ok but the water pump housing may need cleaning. But at least the head is not leaking gas into the radiator. This is one case where I'd use a radiator flushing agent to clean the block

The plastic impeller could have seized allowing the pulley and shaft to turn. You could be right Charles
