Even if there is a big load on the altenator it is still less than a waterpump. Most of the race cars run electric pumps to gain a few extra HP. Except the drag cars running on methanol. They run without any form of a cooling system.

Problem with meth is you run so rich, if the car is idling for too long it goes past your rings and then your oil is useless. Thats why the guys have glow plugs in their sumps. So the oil is warm before they start the car. So when they start it they can drive it hard from the work go without having to worry about damaging it.

Hi Danie
I wonder if the radiators used in Australia are the reason they don`t complain about overheating. I also mentioned a long time ago about the radiator specialist, who commented that radiators should always be painted black to help dissipate heat. That Australian radiator is painted. If I put foot on mine on a hot day I see the temp climb higher than normal. This is a sure sign that the cooling is at it`s limit.

Hi Guys.
I had some overheating issues yesterday. I thought my pipes were clogged and decided to flush the cooling system today. The one thing that bothered my, was that when you squeezed any pipes, coolant would push back into the plastic overflow bottle. Upon investigation, I found the radiator cap was too short.
It did not seat on the radiator and did not close it off at all. Now what kind of idiot would mod a cooling system to the point of removing any efficacy from it?!
I got a long necked radiator cap and it seems fine now. Have had it idling for about 45 mins without pusning out water. Which it did this morning.
I will however add an electric fan like I saw on Ari's yesterday. Crawling offroad like we did yesterday will probably push the heat beyond my comfort levels, even with the correct radiator cap.
As for the black paint on radiator influencing the capacity? I will leave that to the experts to contemplate.

Hi Spencer
Did you get the pipes cleaned out? How much muck was in there?

Hi Spencer
I would be interested to know the part no for the longer radiator cap. There are a couple listed in the catalog but I have never been able to get one. I also do not know what their setting is. The Niva should be 70kpa (from memory). I have 2 fans fitted in front of the radiator, controlled by a thermo switch fitted where the old heat sensor was fitted the old EGR system, along with an override switch and indicator light. The painted black radiator originated when I was in a hurry for the radiator for my MK2 Jag, and I said not to bother painting it, thinking it was cosmetic only.

Ronnie Hi Ronnie While Bobby now confirmed that the brass radiators (tanks at the top and bottom) are the only radiators which are used in Australia, I just wonder whether CMH ever did proper tests on Ladas - fitted with the common plastic side tanks in South Africa. I fully agree - why do the Aussies, (with similar weather conditions) never mention anything about overheating problems ?? Again, I am very suspicious about the local supplier's "keep it original " talk - I could be wrong, but I still believe that this "keep it original" talk is nothing but sales talk acrobatics. Danie

The Aussies have moaned about overheating in soft sand driving on their forum. They just dont moan as much about it. Ari

Hi Danie
It`s keep it original until it suits them. According to the Pretoria Agent the original Thermostat is no good for RSA. He then proceeds to fit his own "SA Thermostat" which is not in any way a thermostat. It has no moving parts and in actual fact does nothing. The Australians use the original Niva thermostat and if you care to check their daily temperature it is virtually the same as ours.

Hi Ari
I think the radiator used here is at the limit of it`s cooling capacity. There is nothing in reserve when needed. After saying that your Niva never at any time that I can remember gave any problem.

Hi Ronnie
On Saterday I never had a problem with my 1 electric fan. and as soon as you start moving at +- 30km/h it cools down quickly.

Hi Ronnie/Ari
The cap was the only one I could get. It is a PJ cap with T1-7 on the box.
Not too much gunk in the pipes. The crunchy sound when you crush the pipes is a red/rusty deposit inside the pipes. I poured some Wynns Radiator Flush in and drove it around. Then I drained the water and took off all the pipes and flushed the engine and everything withclean water. Added 2 bottles of Game's finest antifreeze and with the correct cap, it looks like I'm sorted.

Hi Guys.
Just remembered. When I had my first Niva, In 2002 the mechanic in Vanderbijlpark said that the thermostat of an old (1980's?) BMW 5 series was identical in shape to the lada one, with maybe just better thermal properties.
If anyone can maybe confirm/deny this?

I think its the one with the m20 engine.

The one we looked at was the m10 engine. thats the e30 320. Look on pg11 of this thread Maybe the old 5 series is different. Worth a look. Charles

Hi Ronnie I dont think the BMW thermostat will work. It looks like the flow of water is different than on the NIVA. The thermostat is for the E30 with the M10 engine. That is the old 316,318 and 320. Charles This Attachments:

Hi Ari
Does your Niva have the plastic tanks or the brass ones?. On the Highway if I push mine the temp goes almost to the point of the electric fans cutting in. As soon as I slow down the temp starts to drop to the normal position. In actual fact the air being forced through the radiator at 120 should be more than a fan can push by itself. I know the condenser for the air con is a restriction but thousands of cars have them and there is no problem I have added an air con to a Granada, a 1600 Laser, and a 1400 Nissan in the past with no problems at all as far as temp goes.

Plastic tanks and I dont drive it faster the 100km/h as I cant select 5th gear. need to fix that soon.

Ronnie.
Do you have any/how many lights, bullbar pipes, kudu horns ect. do you have fitted on the bumper infront of the radiator?

I think I still have a set of Reindeer horns at home for the Lada, more fitting than Kudu I think.
