nooo overheating, was like 8-10C during the night and this morning it took some time until it started haha.

Hello guys! It was the mounting for the thermostat that was broken. The car works now. Do you guys also have problems with cold start?

Thank you very much! :)

Maybe this one works? https://www.autodoc.se/3rg/10262467#termostat

@Thefeliciahacker @Papez Yeaapp, i checked it and thought it was fine, but i have now found a little crack in it so thats why all thermostat breaks and the car overheats. Could anyone possible send link on what i need to get? Like a part-number or something? For me the only place i can order from is kind of Auto-doc. Sorry for late reply have been gone for a few days.

Should also mention that the radiator is in a nice condition, would not even call it dirty. just some insects. also, the heat sensor, i think i have a blue ring on now, but i also have one laying around with a yellow ring. Dont know the difference lol

Yea okey, lets keep this thread to overheating and i will make future threads about other stuff on the car. haha! like @nta16 said. Update for today would be that the car first got a lot worse, overheated super fast and i got so confused, But then i changed back to the "first new thermostat" (i changed from a new one i bought to another new one to see if there was a difference) because the second new one i put in broke right away...? the pin was fully out and stuck. But now when i changed back to the first new one it works better. I flushed the system a bunch of times and used some weird cleaning stuff. Started it, let it run, open up, flush and repeat. The mix between antifreeze and water is like 35-40% antifreeze and the rest water. AND NOW, While not using the fan at all, the car goes to around 100c MAXIMUM, i never gets over it at least. So thats better, the fan doesnt really help much aside if i am idle running the car, then it stays on an even 90-95. So thats good. But i still have the problem while driving that it goes between like 95-100 depending on if its uphill or downhill. I am guessing now that its just air in the system? But i burped it and waited a long time to see any bubbles but didnt see any after a while. And all this while not running the "AC" fans on max heat. I had "cold" fan mode. so i mean its an improvment but yea. Still not perfect. I am thinking about handing in to a shop so they can troubleshoot it but i dont know, what do you guys think? THere is also probably no leak in the head-gasket, there is no white smoke, the coolant is clear brighter blue. Also checked for any kind of "build up" on the oil-fil lid and stick and didnt find any.

I have tried two new ones, they both open 87 and they do.

I made sure the coolant level was over the engine, Put a thing on it, air tight and always had the car running. It burped and stoped after a while, the thermostat opened it burped a lot and kept it running another 10-15 minutes. With the heating on max the whole time. Took of the canister while the car was running, took out the overflow coolant and put the cap back on. I did hear wezzing from the cap later on after a drive which i guess was just pressure releasing since i live in the mountains there is a lot of ups and downs and pressure change.

Its like 50/50 mix. No leaks in the cooling system now I burped the system for a whopping 30 minutes. just to make sure. Watched like 10 videos too just to make sure i actually did it right.

So if i go for a drive without the heating on MAX, and the Cooling fan always on it just keeps on getting warmer and warmer, will def start boiling. I dont push the limit because i dont want it to boil. If i go for a drive with heating on MAX since start it stays on 90. and for the first weeks of owning the car it alawys just stayed perfectly on 90. But now it keeps on getting warmer and warmer, except when im going downhill haha...

I kind of doubt that they had a fan-switch. it was a 90 year old couple that have owned the car since 2003. But yea it does not look standard. I also dont see any modifications in the Cupé. Everything looks standard. (except the radio i changed) i mean the fan was working on temp untill 3 weeks ago. (about that the car is fine, hahaha i have no idea, but like it drives well, main focus now is just to fix the overheating issue)

Okey update about the car guys, The fan does not help shiet with cooling. I put it directly to the battery while driving and the car still overheats. SO, that said. If i run full speed on fans("AC" i know its not ac but dont know the name haha) on the hotest setting the car does not overheat, Then it stays 90C. Like fairly stable. If i turn off the AC and do full throttle cooling fan it still overheats. BUT the radiator still gets evenly warm/cold. so the flow seems fine in it, same goes for the pipes from it. The thermostat seems to open like it should. I dont notice any oil leakage or dirty cooling water. Its "perfectly" blue still. What do i i try next. headgasket? Waterpump?

Everything works fine except for the cooling fan. All cables are checked, And i am guessing its just the thermostat switch in the raditor that is wrong. (i bought one for a car with AC), have ordered a new one with only two pins. I put the old one in boiling water and still didnt connect. The second thing is that the radio (i am guessing) is, i dont know the english word but alaways consumes electricity. Even when its "fully" turned off, my phone is still connected to its bluetooth. aaah okey i see, i think my father has one of those. About the battery, i have a charger so ill just try that overnight then! Thanks mate!!

Oh dang, thank you so much, def worth 7 euro! Yea okey ill smell. i dont think there is enything wrong because the coolant is clean and im not losing oil and the engine runs great on normal temp. What do i smell for? like an oil smell?

hahah yea i 95% trust my dads work but even that is worth double checking. Yea i have only had the car for a month so i havent done much work on it. I might try to open up the gasket and see if it looks good when i have time. tbh i checked the manuel and it was very not informative when it comes to DIY information. But yea, i will check breaking oil, head gasket and go over the wiring. Breaks are changed, spark plugs are changed, did a solid oil and filter change, also going to change the fuel filter, I think the cooling system works fine now, the thermostat is new, opens when it should, The belst are in new condition (changed recently), the breaks are still in a fine condition too. So its just the fan right now i need to get working. If it doesnt work with the thermostat switch i ordered i am going to wire it to a switch but i really dont want that. I also think the new radio i put in is drying the batteri even when the car is turned off and the radio. My phone is still connected to its BT so i need to change the wiring and connect it through the ignition. woke up today and the battery was dead. Might as well change the battery to i guess.

I have bleed the system fully and rinsed many times. i think its the switch tho. I put it in boiling water and tried to see if it connected but it didnt. But it could also be the ECU you say?? The fan is working, i trued directly connected it and then it works

Hopefully haha i wont be able to open the engine up until im home which will be many months from now.. It must be the thermostat switch no? I have literally checked or changed everything else 😂

Its not leaking oil or coolant now either and still seems to run fine? So should be fine right?

but i haven’t been driving it while overheating 😅 it got hot once. Turned off. went home, and then i have tried 2-3 more times but i have only let it go up to like a 100c and then stopped.

Since i thought my car had AC (hahahaha) i bought the last one...

Have i bought the wrong one, would this one work? https://www.autodoc.se/vika/13159301#termokontakt-kylarflakt I have already bought this one lol... https://www.autodoc.se/ridex/15781333?_gl=1*5uayzp*_up*MQ..&gclid=Cj0KCQjwh7K1BhCZARIsAKOrVqHAXe-I_mXaD0qZLT5qfCS83ueYApWJ5tKUx9ba1ZQ0d6b3cpx2jBwaApZkEALw_wcB

Thia is their cable management two loose ones are the thermostat switch the 3 pin next two them goes to the battery (the red one in this does not connect to a cable only yellow and brown) and the brown red big one goes to the fan.

Hellooo again. SO the fan works it’s obvious to me know that they have done something here. The old thermostat is only two pins and its broken. I put it boiling water and it didnt connect. So i have a new one. It has 3 pins and now im confused. Please help 😂 it seems like they have done something, ALL the cables work, i have measured all of them. So. from the battery comes a yellow and brown (grounded) cable. The brown cable goes directly to the fan motor. The yellow goes to the thermostat and then the red goes from the thermostat to the motor fan. what do i do blue is to the fan yellow circle is to the battery (the red one does not continue it just stops there) Res circle goes to the thermostat

Yea i will go through the cabeling at some point but ill do that back home where i have my father who is a mechanic 😂
