coolant level dropping-what to check?
i guess i need a tester with pump?
or just something like this? https://www.aliexpress.com/item/1005...c&gclsrc=aw.ds
then, how would i use it?
thanks

 

srt6?
oil on dipstick look ok?
car misfiring?

 

i hope this is just a leak in the connections.

 

have you found any evidence of where the leak is?

 

thank you. yes. as i dont have a pressure tester i took to my local mb shop. they tested with pressure tester.1 of the hoses under had a crack. replaced and all is o k.
at the end of the day was better this way, as when is under is very convenient to have means to raise the car.
thanks again.
still would like to learn more regarding which pressure tester some1 here has used.
you never know when you are going to need it again and it could happen at the top where it is easier to fix it.

 

still, regarding to this: https://www.aliexpress.com/item/1005...source=admitad
i would like to learn how it is intended to be used...just guessing: do you connect it anywhere and start the engine and when the pressure raises you can find out where is the leak?
still, am not sure how to connect it. i hope some1 has used it or any similar.

 

found this that comes with radiator caps that fit mercedes:

comments?
thanks

 

look at the pictures on the vendor web page :

 

thanks. i saw that but will see into my car and try to find where can i plug it.
thanks again.
but then, how you increase the pressure without starting the engine? and if you have to do so, i dont feel comfortable nosing in with the engine running...
or start, see the pressure raises, and then stop and hurry to check.

 

and here we have several tests: https://www.google.ca/search?q=how+t...UxRBlUQ4dUDCA4
seems that it can be performed at the radiator or at the reserve tank.

 

Yes, and the engine should not be running.
