I never owned a NE, but my two cents

On the upper side, one end of the hose connects to the radiotor, the other end should connect to a small piece bolted to the engine. This part is supposed to contain a thermostat which opens and allows the coolant/water flow after the engine temperature rises to a certain level. This is removed by mechanics in many cars, check if ur's has it or removed. If it is missing, u may try find a replacement. This will enable the engine to quickly reach its operating temperature as water flow will be restricted.


My mechanice removed it from our Ambassadors saying it is of no use and may create problems, but this may be of use in your case.

This was also removed in our old 800 by A.S.S because it was getting stuck and after reaching very high temperatures it suddenly used to open forcing a lot of coolant out of the coolant container cap because of suddent expansion.

Off late I have observed that the engine is taking too long to heat-up. The temperature gauge hardly flicks and moves up after half an hour of running. The ambient temperature is at around 15-30deg C. I remember this was not a problem earlier but don’t know since when it has started behaving like this. Problem is not the temperature gauge but the lethargy of the engine when cold. Once heated up, it works fine. I have checked below points but I am still pondering about the reason:
1. Thermostat removed & checked for working in hot water. Works perfect.
2. Changed from the NGK Iridium plugs to normal plugs (NGK BP5ES) with 0.9mm clearance
3. Tappet Valve Clearance checked to 0.25mm at dead cold
4. Ignition Timing checked to 7deg BTDC. Dwell angle at 55deg & point gap at 0.50mm.
5. I had changed the radiator fan some years back as the OE blades got chipped. Currently it is a 4 blade fan from the Padmini.
6. Using Engine oil of Grade 20W-50

Is there any other point I have missed & that is causing this cold behavior?

I'll don't recollect the diameter of the pipe as this was done by my father long time back. Should be anywhere between 2 to 4 inches. Best option would be to take an old hose pipe, cut it at the desired place and then take it to the shop while purchasing the GI pipe. The pipe is of equal diameter throughout with no bulges at the end.

Checked up the 118 NE Workshop Manual and looked up the Engine Cooling System Trouble Shooting table. For OVERCOOLING, there are only two causes & remedies mentioned.

• Inoperative Thermostat
• Inaccurate Temperature Guage

The remedy mentioned for both the above causes is to Replace!

Thanks but I have checked that first & mentioned it as my first point.

Thanks but Both things checked boss.

Anyway could it be due to a broken surge tank cap? The cap has a broken rubber seal & moves freely on the bottle without sealing it!

I am not sure about the effects of a broken surge tank cap. Just had a doubt whether if it could be due to an issue related to the component described in posts 391 and 392 (links given below) on page 27 of this thread? Experts please check and comment.

Thanks for the link. Yes I know about that Spring Flap on the manifold & have checked it for movement - It moves freely. But I don't know how it functions. I mean how would one know if it is not working?

I had 1998 model 118NE Viceroy model. I purchased it through auction from Karnataka Bank (It was used by GM of Karnataka Bank) in 2002. It was with me till 2006. It was a beautiful car but with frequent maintenance problems.

Glad to see another Team-BHPian who had a Viceroy! We also have a November 1997 Viceroy and a 1989 118 NE. By the way, there is a separate thread for the Viceroy and you can see the pictures of our car at this link : http://www.team-bhp.com/forum/indian...t-118ne-3.html

As you rightly pointed out, these cars do need frequent maintenance but the effort is worth it once you hit the road. I have done two long trips in the Viceroy.

One was a 1500 km trip from Hyderabad -> Horsley Hills (including Talakona) -> Hyderabad.

Travelogue : http://www.team-bhp.com/forum/travel...s-viceroy.html

The other was a 1960 km trip from Hyderabad -> Coorg (including Bhagamandala & Talakaveri) -> Mysore (stayed a couple of days for sight seeing) -> Bangalore (pass through) -> Hyderabad.

How much time / kms does your engine take to warm up?

These are pics of the temperature guage reading of our Viceroy.

This one was taken when the car was cruising on the highway at 70 kmph with AC on. The ambient temperature outside was about 27 degrees.



This one was on the same day but taken when we reach home after 8 kms of city driving with AC on. The ambient temperature was about 25 degrees since we reached the city at night.

Hi Rahul,
How come the needle turns red at night?
Even the temperature needle in my car would show a similar trend. But temperatures dipping low in this season, and my drive to office is really short (3Kms) the needle doesnt really shift from its home position.
Also I am pretty sure that my carb needs a cleaning and is running rich these days. Which adds up one more factor for the engine running cool.

Well, there is a ghost in the car who does the colour changes from time to time! Jokes apart, the credit for the colour changing needle goes to the Auto Correct option in the Microsoft Office Picture Manager application!

As you correctly mentioned, in winter season, it takes a long time for the engine to warm up. And I think that the Viceroy takes still more time since the cooling fan has a cowling.

But that would not make it run crappy as the Viceroy had an Auto Choke Mikuni Carburetor.
What about your 118NE? Does she behave like mine - it takes a run of 5kms or 15-20 minutes for it to get in 'tune'. BTW, i use the choke only for starting and shut it as soon as the initial hiccups of a cold engine disappear.

[Scarlet_Rider]

The Viceroy's Mikuni carb has a manual choke. It does not have a auto-choke. I rarely use the choke to start the Viceroy. Even if the car is not used for 2 to 3 weeks, it starts in the first attempt without the use of the choke.

Our NE having the Hitachi carb runs normally when cold i.e. the engine revs smoothly. Since our house is in the heart of the city, we don't get a clear road for the first 2 kms when we go out. This in a way helps the engine reach the operating temperature sooner!

I removed the seat covers last week but found a peculiar problem on the rear bench after removal. There is a 2" gap on both sides showing the ugly buckle. It is not that the seat in not fitted properly - I checked it 2 times but could not remove the gap.

Hi Guys,
Just a few pics of my LatDat (Latin Datsun). Thought the 118 gang might like these pics of my car.

[shineshine]

OMG.....I like that... Thats the best mod i've ever seen in 118 aka your Latdat

Just put a nice fake air scoop at the middle of that bonnet and you will have extremely good looking MUSCLE CAR!!!
