Was usefull, thank you 👍

[@jonsmithunwessen1927]

Good vodeo thanks, did you or do you have to drain all coolant before doing this. Cannit be done without fully draining?

[@How2FixIt1]

Thanks for your comment. It’s best to drain radiator with plug at bottom or remove lower radiator hose. Catch it though and reuse or dispose of responsibly. What ever runs out is enough to do the job.

Did you have to bleed system after when putting water back in tank thanks

[@How2FixIt1]

I used a purge tool. But you can do it without just might take a bit of time to bleed if you get a air lock.

Hi, please help me. I was using your guide and while replacing the coolant flange, I broke off one of the mounting screws and now the car won’t start. Could this be the reason why the car won’t start? I also disconnected all the plugs but they can’t be connected incorrectly. Also, when I turned on the ignition, there was a strange buzzing sound from the fuse box, but I tightened the screw that holds 2 negative cables and the sound stopped. I don’t know if this could have damaged or blown a fuse. Thank you and please help :/”

Is the engine cranking over when trying to start it.

[@mkubamalecki2959]

@@How2FixIt1 yes starter works

[@How2FixIt1]

@mkubamalecki2959 so I assume it’s just cranking and no start? Check the coil pack multi plug. These do occasionally easily break. And double check all your work. Have you had battery disconnected?

[@mkubamalecki2959]

@@How2FixIt1 Yes, the starter is cranking but the car won’t start. As I mentioned, one of the three screws holding the coolant flange broke off, and I don’t know if it’s taking in false air, which is why the sensor reading from that flange to the computer might be off. Regarding the battery, yes, I removed it to get access to the coolant flange, and it was quite difficult to reach, so I might have bent some wires. Best regards and thank you for your involvement.

@mkubamalecki2959 the broke screw won’t stop it running. I will guess you have Kraft a lead of the battery. Have a really good look around. Sometimes there’s a few that bolt together on the distribution connector. Check those fuses too if there’s any present. Your welcome. Hope you get it sorted. Good luck!

What is that part please the pipes go to.

[@How2FixIt1]

It’s called a coolant flange.
