I don't see any mention of an idle jet, just a mis-labeled "pilot jet" of z80. that's the air jet on top of the emulsion tube. DON'T CHANGE THAT TO A 55!!! Idle jet is on the SIDE, not on the top, inside the barrel, that's the air jet, with a "z" in front.
Insufficient advance (say 5-8° retarded) will cause overheating and poor mileage. WHY DID YOU TOUCH THAT after it was set?
Hope this helps untangle this mess. |
Cuz I feel like engine run bit advance then mechanic told me to turn a bit angle. But it's getting overheat before i change the angle. |

Your going to have to ensure #2 tins are there. If you have sled tins you may need a mirror and a bright light to see them. Look above the pushrod tubes. They should be attached to the bottom of the heads.
Is that fan shroud chrome? Or do the pictures just look funny? It might be an empty shell with no internal veins to direct airflow. It has the indentation like the OG ones, so I can't tell. Does it have the doghouse cooler (offset) or the smaller inline cooler? If it's doghouse, does it have the two tins to direct airflow through the firewall tin? All the tins have a job. VW would have not used them if they weren't necessary. Tell your mechanic to quit removing parts of your cooling system. Does he pull out radiators from liquid cooled cars too?
The drives side intake endcasting has a raised bump on the top. Is that sealed? Or is there a hole there for some kind of vacuum barb? You need to make sure you don't have a opening letting in unmetered air into the system. It will cause a very lean mixture, melt pistons, and be impossible to tune.
I don't know what that other thing is hooked to the manifold vacuum you posted a picture of. Is this an autostick transmission or standard?
Also, is this a new problem? Or did you just buy the car and the car came this way? |

Yes, it's chrome. It has a doghouse but i'm not sure about a tins inside. It's a standard transmission.
Everything were like the same as day my dad bought many years ago Except the spark coil. But Overheat and Over-consumption will happen when i drive long distance. |

Same old post with same old problems , this planet is full of a bunch of shitty mechanics .. and then the same old guessing game ,
Why not use the search function and learn something ...

I did a search for overheating, and came up with very little to help this guy. Maybe we need a sticky for overheating where it includes the things to check first.
Everybody has a different engine and mods, so it's hard to identify what is needed for each case.
This guy is in Thailand and apparently has a poor mechanic and would like to fix it with a little help from the forum, it's a great start.
We all start the guessing game and hope the OP takes our advice and gets the problem solved. We all want to see VW's on the road.

Already did sir. I did it about 1 and half year to solve this problem because my mechanic can't solve it that why i start a post

Because all of these are technical vocabulary and ofcourse it's a foreign language to me that make bit confuse.

Not sure how much it matters but it looks like the nut on the stud that holds/braces the intake manifold to the case is loose.

| Make sure you have the wider fan and not the early thin one. Thin fan will have gap between fan and shroud.and inefficient distrbution of air. |

You haven't even verified you have all the tins in place yet. There has been plenty of things to check and you haven't done so.
1.missing tins
2.distributor timing set/advancing etc
3.check for unmetered vacuum leak
4.valve lash correct
5.verify jet sizes/choke operation
6.plugged up engine fan, or debris clogging the air passages around the heads.
There is nothing you can just adjust and "fix" your problem. You need to verify each of these items are verified correct. |

Is this the same "mechanic" who can't figure out why it's running so hot? If so, stop asking him questions because he is clueless.

I agree with that but it's hard to find a better mechanic here. Better mechanic is far from here about 600 kilometers  |

Then either sell the car, or start learning to do it yourself.

There is lots of useful info here, and these books can help:
-John Muir's "How to Keep Your Volkswagen Alive".
- Tom Wilson's "How to Rebuild a VW Engine (or something like that -exact title escapes me)".
-Bentley Manual for your your year. First one I'd get.
But start by doing the list of things Pruneman99 gave you, it should solve or help identify your problem. Good luck |
