Over heating can also be caused by not enough water/coolent in the system. Best way for filling up (what works for me) is to have the interior fan running on full and having the heat set up high as it helps getting coolent in the entire system.. Air-conditioned I believe is different entirely. Thank you for vid, it has helped me out with the different names for the sensors. Now just the coolent sensor...
This is true, replaced thermostat 80 degree. And then replaced radiator fan, and also sensor. Saw that my fan did not go on. So I checked the radiator sensor it was a 95-90. So my radiator started pushing water out, as the fan did not switch on, looked on the old radiator sensor it was a 88-74 degree. Put back the old one as I knew it was not faulty. Put water in it, bleed it and after it reached I think it was about 84 degrees boom on went the radiator fan. Please guys listen to this good advice and save yourself a lot of headaches. You know your car. If it does not seem normal it is not normal.
Hi bru i had experienced something weird last night my fan stopped working so i replaced it with a lukas thermostat 2pin and i checked wiring for relay and fuses are good getting power to the fan switch and fan but not kicking in automatically normally it should
Hi .when you say not kicking in normally. Do u mean its not coming on at all,or coming on too late ..if it coming on too late make sure you have the right thermoswitch which should kick in around 92 degrees Celsius.. There should be that number stamped on the switch
I want to ask a queation my jetta doesnt use any water and do serculate in town guage shows fine but on open road it goes up quite high but never boils or overheat Also there is not a lot of pressure in the bottle
You either have an air lock in cooling system.. Or begin signs of a blown head gasket... Or you may have a water leak on the external parts of engine., like hoses, water pump...Welsh plug. You will have to hunt for it..
Some mechanic's say that you must take out the thermostat and run the Golf1 with out it. Especially if you do lots of stuck in traffic stuff. As long as your fan kicks in at the right temperature. Manual choke cars they say you don't need a thermostat. Only on Electronic Choke cars this is not recommended. What is your take on that?
The Thermostat was put in an engine's cooling system for a specific purpose, so my take is, don't take it out. The car won't run at its optimum performance, and you can cause long term engine damage, and use more fuel etc.. I have a video on my channel about the Thermostat . You could view that one. I go into more detail therein
Excellent.. thank you!! Question: ...any experience of erratically water guage that shows rising temp starts even flashing red light when the water is actually not overboiling? I changed now 3x the top sensor with the one wire on it ...and face same problem. Changed both fan sensors and even thermostat too. Can you advise? Golf mk1 cabrio 1986 1800cc?
If you have replaced all those parts ,maybe time to check out the cluster in the dash..I also have an issue with mine working erratically,also replaced temp sensor ,but still the same.., I really don't want to fiddle on that cluster .will have to get someone in The know .I'm also thinking it could be an electrical issue like a bare wire touching metal somewhere..I thought it would be as simple as changing a sensor or removing corrosion on contacts ,but I still haven't solved mine.
Hi boet ,completed all checks ,changed thermostat,water temp switch,new radiator,bled system ,new water pump and cleaned hoses yet still having overheating issues 😤what could it be ,pls assist
Hi,Have you thought of the possibility of blown top gasket? By the way have you replaced or checked the Thermoswitch on the radiator..This activates the fan at the right temp , usually around 92 /95 degree Celsius
Hello I bought a manifold from my mechanic my manifold had only 2 pipes and his 5, what I want to know is it possible for him to install it? On my car without any problems?
I took my thermostat out do you think it's good idea or what reason I took it out was the top hosing gets very hot and the bottom one by the thermostat is cool but it's still same now with the thermostat out my top water pipe is still hot any advice should I replace my water pump?
If u take off the thin pipe running to the filler bottle is there coolant coming through? .. That's a sign of the water pump being finished, or maybe u have an air lock.
What is the normal operating temperature? I have the vdo gauge that shows temperature of the coolant so just want to know where it should be between because sometimes it goes over a 100 degrees Celsius
Well the vw engine operates at its optimum just before 100 degree Celsius... The Thermostat opens up at 87 degrees Celsius.. Fan comes in at around 92 degrees.. If you going way over 100 degrees have your thermo switch checked..
Could be the fuse, or the connection behind cluster, or the sensor which is situated on the front of cylinder head. The wire could have come off, or corrosion causing a bad connection.
Hi Lukholo,. I'm sorry to hear. It looks like your cylinder head gasket was not torqued down properly.. Unfortunately the head must come off again for inspection.. Could also be a fine crack in the head... Take to engineeers, if you able to, for inspection. All the best
Pj🎉🎉 you have helped me so many times, thank you

I want to guess that you spent some time in South Africa....'Kruntchy' gave you away....So, Hello from Canada! Hope you're well! Great video!
Hi thanks, well I am from South Africa.
@@pjs-golfmk1-diy I love accents and yours is cool!
Thanks Boet for pointing out about the 87 degrees for the thermostat .. now I know what to make sure I use :)
Also check your ignition timing , and a very lean air fuel ratio also causes overheating
Thanks
You shud start a TH-cam channel 😊👍
Your information is good,I have been a VW mechanic for 35 years
Love the content sir / can we plz have a golf review and things to check when buying a golf and which one is more reliable
Hey Lawrence, thanks, and it's a pleasure. Thanks for the suggestion too. Will certainly consider it

Hi just a quick question, what might be the problem when your car engine gets hot quick and water needs to be added everyday
You either have an air lock in cooling system.. Or begin signs of a blown head gasket... Or you may have a water leak on the external parts of engine., like hoses, water pump...Welsh plug. You will have to hunt for it..
Hi PJ all you videos is so helpful. I want to know if i can put 1.6 jetta 3 engin in polo classic 2007

My water is boiling in the water bottle please advise
Do you have a video on how to bleed the cooling system?

Hi,Have you thought of the possibility of blown top gasket?
By the way have you replaced or checked the Thermoswitch on the radiator..This activates the fan at the right temp , usually around 92 /95 degree Celsius
How can I contact you directly? I need advice asap on my 1989 fox please
Hello I bought a manifold from my mechanic my manifold had only 2 pipes and his 5, what I want to know is it possible for him to install it? On my car without any problems?
Hi.. 5 pipes?.. I can't seem to picture that.. Are you referring to the intake mani..?
@@pjs-golfmk1-diy yes the one the carburetor is resting on... I think it's 4 pipes for water and the other pipe is for the master cylinder
Hello is it a good idea to install that manifold?
Can you install aftermarket air filter on a carb?
Yes
Induction kit
I took my thermostat out do you think it's good idea or what reason I took it out was the top hosing gets very hot and the bottom one by the thermostat is cool but it's still same now with the thermostat out my top water pipe is still hot any advice should I replace my water pump?

@@pjs-golfmk1-diy What about a thermostat with 87°C but it's corresponding thermoswitch is 97-102°C for a vw, what can you say about that?
@@nonsookeke3396 well the fan would just take a little longer to activate..
Been driving without any thermostat. Common cause of overheating is incorrect timing of the engine...
Driving without Thermostat seems fine, but it has so many disadvantages for the engine, causing damage.
Howzit What do I look for why my heat gauge not working?
Could be the fuse, or the connection behind cluster, or the sensor which is situated on the front of cylinder head. The wire could have come off, or corrosion causing a bad connection.
@@pjs-golfmk1-diy OK lekka Thanks man will have a look at fuse but wire all good thanks again
I did engine , ,now I notice water bottle is having oil
Hi Lukholo,. I'm sorry to hear. It looks like your cylinder head gasket was not torqued down properly.. Unfortunately the head must come off again for inspection.. Could also be a fine crack in the head... Take to engineeers, if you able to, for inspection. All the best
