Cuore Automatic Maintenance Schedule

[geek.maan]

indeed -- on very low speeds or idle it is understandable that its AC won't perform well. What bothers me is its tripping on high speed

[dayrider]

why don't you check the condenser and the filter, your system could be dirty and requires cleaning, usually tripping is caused by a dirty condenser and if not dealt with immediately, it results in proper issues

[geek.maan]

interesting , last filter change and condenser cleaning was in March 2016 soo yeah maybe that too. Thank you

[muhammad.irtiza]

Is there an AC filter in Cuore? Or are you referr to Engine Air Filter?

[geek.maan]

AC filter in Cuore

The dryer unit I suppose, the one attached with the condenser

[muhammad.irtiza]

Interesting.. will keep in mind when restoring my AC. Please keep us posted on updates

[muhammad.irtiza]

As for the updates on my car, it has been 15 days since I got the car fixed from @omersiddiqui5482 bhai's mechanic Kamran Bhai, and the car has been running good

We have given the car to our relative for a week, and aside from him jamming the mirror on driver's side, the car is not giving any complaints. I have been trying to dig into the horrors inflicted upon my previous mechanic on the car when I came across a good piece of information to explain what was happening in my car.
https://itstillruns.com/effects-retarding-ignition-timing-horsepower-7482734.html

Effects of retarding ignition timing on horsepower
Vehicle manufacturers typically set the timing at a default that will lower engine temperatures and reduce emissions. Advancing this setting increases the engine's horsepower by firing the plugs earlier in the compression cycle. If your plugs fire too early in this cycle, you get so much pressure and heat in the cylinder that the fuel-air mixture can auto-ignite and damage your engine.

Understandable. This might be the reason why the head gasket blew within a month. The presure and heat in the cylinders was so great that the new gasket gave in. The first thing Kamran bhai pointed out, as soon as he opened the hood, was this. The timing was way too advanced, and the previous mechanic boasted to us that the performance increase was due to his work. Truly, the car's throttle response was so beastly that I had to ask him twice to decrease acceleration.

It's also easier to start a vehicle with retarded timing since temperatures and pressures have had more time to build in the combustion chamber so they'll ignite quicker.

Agreed. My cuore was starting as soon as I turned the key to start position. Even if it was left overnight. Now it takes 1-2 seconds to start, a negligible difference.

As for the extreme heat, and my inability to diagnose the overheating in time, my father did point our on two occasions that the car was overheating, but I was trusting the heat gauge way too much. I came across @Xulfiqar bhai's post on this matter:

80 Series Discussions

btw - toyota and infact every other japanese brand temperature gauges are absolute garbage, they will stick to mid position if the temperature range is between 80~105C - they will move up a little at 125~130C (head gasket shifted) and then immediately ram to max when the temp goes above 130C. - that is if everything is going good.

I guess the only thing that was stopping the engine from coming apart was the new cooling system, which gave the head gasket a slow, instead of a quick, death. Even tappets were not adjusted properly. What are your opinions on this? Does this theory makes sense?

[geek.maan]

Does this theory makes sense?

sounds reasonable

[omersiddiqui5482]

@muhammad.irtiza sounds quite justified. Chalo atleast the problem is now solved and the car is going good...

[nauman005]

Hi there. I want to ask that i have cuore 2007. If i m going to some where and my ac is on and now i have to stay for say 5 minutes on road n family is in car can i keep ac turned on for 5 minutes while car is on idle standing??? Plz help me.

[omersiddiqui5482]

Yes you can keep the AC on Bhai. No harm in that.

[muhammad.irtiza]

Planning on getting the suspension work done in the near future.

Problem: Most of the problems have been rectified after installing OEM bushes and good quality boots. The car's steering is light, responsive, and firm. However, on turning full from a stop, the suspension produces a kar.. kar.. karr.. sound.
Most probably the CV Joint is going bad. Kamran bhai suggested the complete replacement of drive shaft, but I am not sure as to how wise that would be, because I cannot find parts online in Pakistan. The following questions arise:

1. Now, if I decide to replace the whole drive shaft, it would have to be sourced from Shershah becuase to the best of my knowledge, new driveshafts are not available in the market. I think that buying used suspension is not wise, considering abusive roads.
2. If new drive shafts are available, where can I buy them new from? And what kind of budget should I make?
3. How safe is it to keep on delaying the work? The car has been working like this for more than a month for now.
4. I feel like both of the driveshafts should be changed (left and right), how wise would that be?

Waiting for your feedback

[omersiddiqui5482]

@muhammad.irtiza new drive shafts are available who says it is not.. Cuore is a common car almost every part is available new...

If you buy them completely new. You can check with Japan Autos at Plaza. They are dealers of OEM Toyota Parts.

My advice is that it is rather better that you take it to your suspension Wala. Or MK Autos and let them check. May be it is only the CV Joint that is a damaged and the rest is recoverable. If it is so it will save you a hell lot of money. CV Joints good quality will not cost more than 3k.

If on the other hand you buy the complete axel Kabli, they can be good but only for those who know who to check them. They will cost you around 5-6K from Shafique Mor.

If you buy new ones the dent on your bank account is atleast 10-12k.

It is dangerous to drive with bad axels. They can break or give out in any deep pockets puddle in the middle of the road. And should be dealth with immediately.

What ever option you choose.. do use the best bearing grease you can find to ensure the life of the Part.

[muhammad.irtiza]

MK Autos, got it. I've seen the shop.

Will get the work done soon enough. Do let me know the brand of grease yoy would recommend... I am totally dumb in this matter. Better not to risk buying used; I don't have expertise neither I have some trustable mechanic to accompany. Is the CV joint grease different than the bearing grease or same?
Also, can you tell me a good brand/specifications of Grease so that I buy and apply with my own supervision.
As always, you've helped me again thanks!

Cuore Axle/CV Joint Issue, Need Suggestions

I am facing cv joint issues in my cuore 2005 on yearly basis. Once I have replaced with KABULI (both outer and inner) with new japanese boot cost Rs.500/- per piece and they last for 8 months only and started giving sounds. Then I have replaced the outer with the chinese (new) and get the inner repaired. Boots were in good condition so they have remain same. However, its over 6-7months and the inner one (left side) is started creating sound again. The sound usually come when there is no one si…

CV Joint grease is different from regular grease -- back in Oct 2018 when i had to get my boots changed .. I used Liqui Moly LM 47 grease -- so far boots and CV joints are running well it has been more than 10000 KMs

[sleeper]

At what time should we replace the full axles?
.
And the cv joints are replaceable easily?..i thought they are fixed and can be repaired only.
.
@muhammad.irtiza let us know ur exp with MK Autos...i hv to take my cultus then

[nfssaad]

easily replaceable.

infact easy to replace then repair.

[muhammad.irtiza]

@geek.maan brother liqui-moly lm47 is the gold standard ij greases as per Xulfiqar bhai's thread named 'grease'. However, I doubt I can find it easily in Karachi. I think you'll be a satisfied man for a long time after that job, considering the grease quality and Islamabad roads

@nfssaad you recently stocked up on grease, any idea where I can buy some? I found the 400g can on Daraz but it'll be double my requirement. Any shops in North Karachi with a good stock of greases?

@sleeper it's quite an easy replacement, as nfssaad said, the repairing is not only tedious, it's useless.

[nfssaad]

north karachi, i dont think so.

i used abro cv joint grease last time. have not had problems so far.

get the liquimoly 400gm one.

you will use 90gm per axle i think. use a cake icing bag and weight out the grease.

[omersiddiqui5482]

Last time i got my lancer's suspension serviced I used Liqui Moly.. it is the best option so far it is available at Plaza but it is expensive but does protect and prevent from wear.. plus I have to use it on all the Cars at my home so what the heck.

CV joint grease has to be different I has to bear a lot of temperature under a stress.

Athe most common Brand available at shops for CV joints is VEGA. I have never used it personally so I can't comment on it..

ABRO products are quite good I don't know why people are not in favour. I have used a couple of Body Wax, interior detailers they are good enough...

@sleeper Bhai CV joint are easily available and replaceble cost quite less the. Changing the whole thing. You need to change the whole shaft when the ROD has become weak and is about to break or already broken. Else don't get the CV joint repaired get them replaced.
