Hi All Can anyone give me the supplier and part number of a radiator cap for my 1.7i. My one is not quite 100%. I saw Danie mention that he had a unoriginal one. Help would be appreciated. Also any other mech reason why the temp should rise to almost boil, all of a sudden, under load. It was 40degrees out, but Bruce has always been fine under load and in the heat. Regards Des

Hi Des
I think you will find it difficult to find a radiator cap to fit anywhere but at the agents. I am also looking for one and when I have time I will look at an alternative set up. By this I mean put a plain cap on the radiator and fit an expansion tank from the likes of the golf with a 70 kpa cap. This should work and then you can use a standard cap.

Hey guys- my radiator cap blew in October last year. I got an exact replacement at Centpart for 40 bucks. The spring and rubber were a perfect match (the cap that blew still had the russian text on). Surely Des will find a proper replacement?

Hi Darryn
Do you maybe have a part number?

Hey hey- here's a picture, lost the packaging so hopefully you can see what's what. The little number to the left of the PJ is TG 3- 13, and the number in the middle is 1410. Hope that helps?

Thanks guys for this bit of usefull info. Nice to know there is an alternative cap available.
Once I get my scanner up and running again - I will post a intersting page from a few spare part prices when we bought the Lada. The cap was R27 at the time.
I also promised some tips on 4x4 driving - I will scan the booklet and post it too.
Regards Marius

Darryn are you still having overheating issues?

Hi Darryn
I went to the spares shop this morning to check the radiator cap which was sold to you. This cap is totally unsuitable for the Niva and you will have serious problems if you continue to use it. A genuine cap measures 33mm from top to the underside and has a double seal. Yours I measured and now I have forgotten the size but think it was 26mm and single seal.You radiator will not be pressurized and will not suck the displaced water back into the radiator when cooling. The worst thing is you will now boil at 100 deg c. I looked at the golf pressurized water bottle but the only cap available for it is 100kpa and the Niva should be 70 kpa. Perhaps someone can comment if it would be OK to run the Niva with a 100 kpa cap. In the catalog there were caps 32mm overall but I could not make out if they were double or single seal nor if the 1mm difference would matter.

Doh- silly me. I guess that explains why I had the overheating issues last year whilst offroad. I could have sworn the replacement cap looked almost identical to the old one, hence much sense of "chuffed"ness on the issue. Thanks for setting it straight Ronnie, guess I'd better pay attention to what happens on this thread...

Hi Ronnie
In regards to the golf bottel conversion. Will you then just use a flat cap and have the bottle connected to the overflow on the radiator? I am also thinking about doing that. Those bottles are also dirt cheap.

Hi Charles
Yes exactly as you say. As far as i could find out this morning 100kpa is the only pressure cap available for the golf expansion tank, perhaps you can confirm this. Do you think the extra 30kpa will put to much extra pressure on the Niva ?

Hi Darryn
The correct cap has a seal on the bottom and a seal at the top and should be 33mm overall height.
Ronnie.
PS I am sure anyone going into a spares shop will end up with the wrong cap. The spares shop here ordered one for me and it had double seals but was the incorrect height.

Hi Des
I am sure when Danie mentioned he has an aftermarket cap his is still of the correct size but did not originate at the Lada factory

Hi Ronnie
The only difference I can think of is the boiling point of the water would be raised. I think that could be a good thing. I can not think of a reason why it will not work. I am really considering this mod. Wil get prices of a bottle and flat cap and then decide.
One must just make sure the expansion bottle is higher than the point where it connects onto the radiator.

Hi Charles
I also think it will work then you can buy a cap when needed anyplace. Even if the bottle is under the level it SHOULD work, as the radiator either pushes the water out or sucks it in.Hopefully the first time the motor heats up the water will simply push the air in the pipe into the expansion bottle then when it cools down it will suck water back to the radiator.

Hi Darryn
What I have said re the cap you have will only apply if your radiator is the original with the deep filler neck. In the picture it looks like it is original. You can measure the depth and check against the cap.

Hi Ronnie
I will get a round bottle. It looks better than the square one. One can link the bottom pipe into the heater pipe ( I think), or into that extra pipe you fitted. That might be a better idea.
On second thought into the heater pipe will not work because the water doesn't flow thru it the whole time. Will have a look tomorrow on what pipe it will work. Otherwise I will just fit a pipe into the blank off I put in the top bipass hose. That will work.

Hi Charles
The extra pipe I fitted from the back of the block flows water all the time. If the golf bottle has a connection at the top as well as the bottom I would imagine the top one can be blocked off if all else fails.

Hi Ronnie
The bottom pipe is a think one and should go to a pipe like that one you fitted and the top on the the overflow pipe on the radiator. Both pipes has to be fitted. If I was you I would just fit a t-piece into that pipe.

Hi Ronnie
What pipe on the back of the head is the water feed to the heater valve? I want to fit the pipe fron there to my top radiator hose and put a t-piece in it aswell for the golf bottle.

Some additional radiator info which might cause more confusion:
The radiator on my Lada is different from almost all radiators on other Ladas I have seen so far - and I always thought that an aftermarket or modified radiator has been fitted on my Lada - but I recently saw a pic of a similar radiator on a Lada somewhere. So I believe there might be more Ladas out there with different radiators fitted.
I once measured the length of the filler cap "neck" of the radiator on my Lada, and compared it with the filler cap neck length of the "standard" spare Lada radiator in my possession - the filler neck's length are slightly different, and to my mind the same cap should not be used on the different radiators.
Maybe Ventz could confirm whether different radiators have been fitted to certain Lada models, and whether different caps should be used or not ?
And if different radiators have been fitted - for what reason ?
Danie.
P.S. Vents, while you do have more info about the history of my Lada, I believe you should also know about the "different" radiator on my Lada ?

Hi Charles
I will take a picture of what I have done with the pipes to the heater and how I have linked them to the front tomorrow. All my pics have been lost when they stole the Laptop.

Thank you Ronnie
I will appreciate that very much. I really think the golf bottle conversion will be a very nice mod for two main reasons. Firstly the radiator will always be full. Secondly you can see if the water level is still correct with one look even when the car is hot.
Hi Danie, will you maybe post a pic or two of your radiator?
Regards
Charles

Hi Ronnie and Charles.
My Landy also has an expansion tank fitted with a plugged of radiator. The tank got two pipes connecting at the bottom of the tank. A small pipe fitted to the radiator and a thicker pipe fitted to the hose connecting the radiator to the water pump. The water circulate through the tank and the water pump sucked the water back into the system.
Ronnie, I will show you next week when I am down there at the coast.
Regards.

Hi Charles Here is a picture of the pipe work at the heater connections. I know it is difficult to see but you know where the heater pipes stick through the bulkhead so you can figure it out. Ronnie

Hi Charles Here is the front connection. You will notice I did not drill the housing I got from Mike as when you drill and tap it the housing is then very thin. I assume that is how the last one broke. Ronnie
