Rebirth of Khyber 1996 - Daniyal

you can flush with thermostat in place too, if you are savvy enough to understand how the system flows. - You use the heater connections to flush with stat in place.

[Xulfiqar]

pour that liquid into a clear container and then see, Make sure your overflow reservoir is clean too, it maybe having oily deposit from previous problems.

Coolant itself is also slick like oil - dont mistake that for oil. - but coolant wont show rainbows like oil does on water.

[miqdadkanani]

Oh yes may be the layer is that of coolant itself. Let me do a flush.

Heater lines are already disconnected and will be made operational after July. So I guess I'll take th traditional route and de-install t-stat first

[miqdadkanani]

Well. Before the radiator was changed (last week) The overflow reservoir bottle had gathered a lot of Black stuff with extreme smell of rotten eggs as I had mentioned before. I had gathered that in a clear jar. After few days, I noticed the coolant in that jar had become clear instead of being red. I couldn't figure out what that was. I think a flush is mandatory. But still couldn't figure out what that black stuff was.

i see nothing wrong in your observations but over excitement enthusiasm of several DIY you have done successfully. Please remove the expansion tank and the connecting tubes wash clean with any detergent. Dry & reconnect do not overfill coolant above HIGH / FULL Mark, use a funnel in place of radiator cap to remove any trapped air. #897 above has more details.

[Xulfiqar]

Black residue in coolant is either someone adding stop leak products or naswaar etc.. or rubber bits eroding from hose pipes because of low quality items.

Here is an example of genuine GM radiator tablets in coolant, this took a few hours to precipitate out like this. The coolant is GM dexcool aka havoline coolant.

This coolant is about 340,000 kms used and was never changed. The dark bits are very smooth like chalk.

[Xulfiqar]

If your coolant discoloured after uv exposure, its dye is bad, what brand coolant was this?

[miqdadkanani]

It was veslee UAE one. I am using this for the time being only.

No it did not lose color on UV exposure. It was kept in the trunk while the car was parked in the basement.

I have somehow lost the picture or either captured it with some other device. This is just a top view of the overflow reservoir before I poured it out in a clean jar

[Xulfiqar]

That just looks like nasty coolant in a really really beatup reservoir

Buy a new overflow reservoir, they arent too expensive, and dont use unbranded crap for something as critical as engine coolant.

“Ustaad Waatar draaping engine” just kidding, its fine nothing to worry imo , white smoke is fine too on a cold start , blue smoke is when yo should worry , and coolant coming is normal because of expansion, ither than that if you have time and resources , do a complete flush.

[brownrose78]

@miqdadkanani So Daniyal, situation is pretty much clear. As per senior and experienced comments here, Nothing to worry(at least for the moment; for the time being), Drive it like your normal routine and then observe if all is ok or something is left for improvement.

The more you will drive, more clear picture will come out.

Cheer up and enjoy your car, you have already spent too much time and of course finance over this, now it's time to Enjoy

[miqdadkanani]

Thanks everyone. More updates on this weekend InshAllah

[miqdadkanani]

Here are the pics. Apologies as I had kept them in a storage and just got them out. The denter wasn't able to set it in despite multiple efforts. They are thick sound proof but won't stick to the body. May be I was doing it wrong.

[brownrose78]

So what is your experience/ conclusion that after practicing of Sound proofing/ dampening for your Khyber?

Which sheet or material you can recommend which worked well in your experiment?

[miqdadkanani]

The sheets that the guy recommended by @hassantaewra installed is for the flooring. For other parts (doors and roof and bonnet), I found some other material at soda water which I will be purchasing this week and then post.

[miqdadkanani]

Flushed the system with plain water.

Added distilled water (purchased at 50rs/ltr) from national chemical company with a little quantity of coolant.

Noticed some leakage at intake manifold (water seeping from the gasket).

Went to Jameel. Mushtaq tightened the bolts but it didn't solve the problem. He asked me to come again next week for tappets adjustment and will have a look again.

[miqdadkanani]

@capsat @nnabeel would the installation of a new gasket require unbolting of cylinder head? Asking because Irshad bhai fixed the intake manifold with the head before bolting it on the cylinder.

[miqdadkanani]

@Xulfiqar bhai, which gasket material should I use to replace this one as it is leaking?

[helper_learner]

@miqdadkanani

Change all of these gaskets when you do the gasket work
