I had this car for 8 yrs, the car was serviced at MASS for the first five years, Engine oil was changed at every service, it used to cost around 4k including labor.(8k yearly) When the car value dropped below 50k, it didn't make financial sense to spend 20% of the value of the car in oil only. I switched to generic engine oil available at the fuel pump. It would cost me rs 900 for a change , including labor. I changed the oil only twice in the last 3 years / 25,000km The engine used to run super smooth, infact I could sell the car easily as the engine condition was excellent. I don't know if it's because of CNG(supposed to run clean) or is it the unbranded companies have improved their quality or the entire thing about service is overrated | |

As for knowledge the understanding is that with the timing light hooked up I have to loosen the distributor cap nut and and then keep turning it until I get 5 Degrees BTDC at idle, since the car is stock I presume I would not have to be concerned with curve or advance at rev's. Next order of business is to actually spot the inspection window with the markings. Quote:

Just to confirm the Injectors on the Zen are 12v right? Or should I get a DC read from the connector? Would I get a read with the injector disconnected and the MM lead's connected in place with the ignition on? As I presume I'd get priming pulses, this is just my assumption. Quote:

Since the injectors would be taken out and put back in I hope to change all consumables that even remotely come in the way, speaking of which are there any consumables that you replace when adjusting valve clearances? I presume that the rubber head cover gasket is reused. Quote:

a) Get all the information, preferably a workshop manual, at hand b) Get the parts preferably genuine MSIL. @Leoshashi can help you with part nos. c) Get the tools including a timing light, spanners, spark plug and other sockets & a feeler gauge for the plugs. Your TW would suffice for smaller bolts. Check the manual for torque specs. And once again - if you work without a TW do not overtighten and make sure you tighten all bolts evenly. d) Get the lubes and other fluids required for the job e) I just remembered timing marks, normally a small 'V' notch' can also be on the crankshaft pulley AND the flywheel. There will be corresponding mark on the engine block. You need to check both sides. Put a dab of white paint to make it more visible under the timing light flashes. To adjust timing get the steps from the workshop manual or a skilled tech. Don't mess with it if not necessary. Modern cars with electronic ignition (with or without distributor) rarely require timing adjustments. If you need to get the wheels off the ground and take them off for the brakes: a) Get a nice set of jack stands and a 2 or 3T floor jack. Now, I am particularly serious about these parts since your life could depend on them. Cars can crush human beings like bugs. So, even when the car is on the jackstands the floorjack should be placed under the car with the saddle just touching a frame or a **horizontal** chassis suspension member. Do not attach the jack to an angled suspension member. b) Also put the spare wheel (or any other wheel you have taken off) under the car. As a last safety fallback use the car's scissor jack (make sure you orient it correctly ) at the appropriate part on the car's chassis. Good luck. Let us know how it goes. | |

You took a good decision by choosing the Lx variant, the EPS on the Zen is really hopeless, too light & vague. A good friend of mine owns a 03 Zen Lx with around 150k km on the odometer, the non PS steering is really brilliant on that car. Here is a recent photo of my car, note the registration number : Quote:
With the AC switched on, the power does reduce substantially in my car. I guess this is normal considering the small engine, I have experienced the same power loss behavior in the Alto, M800 with the AC on. Somehow the WagonR F10 engine is better in this aspect, the power loss isn't as high as it is in the Zen. While climbing up inclines, I make it a point to switch off the AC. On the subject of the Zen engine being sluggish when cold, my Zen idles really high when switched on for the first time in the morning, the idle RPM remains high until the engine is warmed up. With the idle RPM high, the Zen accelerates briskly even when cold. Now, say if I switch off the engine after idling for a few seconds (first crank of the morning), next time I switch on the engine, the idle RPM doesn't rise (even though the engine is cold). In such a scenario the engine does fell sluggish for 2-3 kilometers. I also briefly owned a 98 Carburetor Zen, that car used to start in the morning with a single crank but would remain really sluggish until warmed up. We also have a 99 Carburetor Omni in our garage, she is also a bit sluggish when cold, though nowhere near as sluggish as the 98 Zen. Maybe it is an inherent nature of the G series engine to be sluggish, till optimum temperature is attained. Quote:
Part number : 33700M70FA0 Price : Rs. 1742 Photo of the HT cable part number: I would also advice you to change the ignition coil, costs around Rs. 25xx. As many members have advised, get the throttle body & injectors cleaned (in that order). I believe these two items (HT cables & Ignition coil) are easily available in MGP stores. What is the fuel efficiency you are getting? Last edited by chiranjitp : 9th September 2018 at 12:07. | |||

1. 33400M70F20 for Rs.2435 2. 33410M70F20 for Rs. 844 Would anyone be able to tell me the difference between the two parts? Because if its only MGP vs SGP then I'd be fine with going for the 844/- one as I do not have a brand fetish and Indian spares would do just fine. I have no clue regarding fuel efficiency. I've done the same 160 km's route here with 650/- worth of fuel and with 1000/- worth of fuel when the price here was around the 75/- mark. So I'd say anywhere from between 13 to 18 Kmpl on the highways and in the city I presume it would be less so lets say sub 10 kmpl. Speaking of fuel efficiency checks, is it normal for the car to spill fuel when filled up to the brim? If so how do yo fill up to avoid spills? | ||||||

It can be connected directly to the battery. Quote:
Ensure the rubber cushions are not damaged and do not interchange the cushions. Buy couple of spare O-rings as it may get damaged during installation. take care to lubricate the ring with oil before installation. The entire servicing procedure is documented in the workshop manual Attaching the price list and parts list for all maruti cars, the doc is old. Use it only to get part numbers and to get an idea on the price. Yes, Tappet setting job requires special tools and additional skill, I give it to a local mechanic. | |||

About fitting the old Zen's radiator grill in your car, I once saw a Zen type I (like my car) with a Zen type II (like your car) radiator grill. So, there is a possibility that the grill may be interchangeable. Though, I have no idea how will the type I radiator grill look on your car. Here is a photo comparing both the grills, dimensions look same to me: Quote:
Here is a photo of the part number of my ignition coil: Quote:
It is not normal for the Zen to spill fuel when filled up to the brim, I have never faced this problem with my car, even our Omni doesn't have this problem. I make it a point to stop the pump attendant at the auto cut-off point, no more filling after the auto cut-off. I suggest you get this problem looked at, something is not right here.

33410M70F20 has only Ignition coil, and is therefore cheaper. Igniters rarely go bad, hence it's not required. Choose the cheaper option. Another information, just for your knowledge. A part isnt SGP if it has *M* in between. For example,33400M70F20 is MGP. 33400-70F20 is SGP. Hope you get this point. Regarding grill, the part is a rare item because there are less Type 3 Zens in the market compared to Type 2 ones. But the part isn't discontinued for sure. Order on boodmo or MGP store, provided you have the right part number. A lot of part numbers on Boodmo and oriparts, specially WRT Zen and older cars are wrong. Regards Shashi | ||

Also, the coolant lines are not bypassed. Can you post a few pics of your 800's throttle body with the bypassing done? And how you have plugged the inlet and outlet of the throttle body? | |

Was the erratic idle issue solved?? Also that high idle rpm you talked about, is that a new development after you did the cleaning?? Regarding the throttle body bypass pics, I'll try to upload them by late evening. I have the pics somewhere in my laptop. Regards, Shashi | |

What I did was, spray the carb cleaner into the outlet when the engine is idle. Just before the engine starts to die I pull the accelerator cable to raise the rpm. Repeated this around 6 times. Is this the right way? The idle issue is there since a long time. I want to rectify that. | |

| Re: Zen and the art of maintaining it Sagar, the cold engine high idle RPM issue is a genuine one with the Zens. My Zen suffers the same. After a cold start in the morning, the engine RPM at idle will stay high until I shut off the engine and restart; else it settles itself after a really long drive. I have spoken about this to MASS many times but they have not been able to solve the issue as yet. Regards, Saket. |
