Tool to pressure test my expansion tank

[Alpinewhite]

Hi all,

I want to buy a tool to pressure test my expansion tank. A simple one which works only for my 95 530i is good enough. I dont wnat to put a lot of money. Is there anything which you guys use and would recomend it to me?

Thanks

how about something like Bruno sells for pressure bleeding the brakes?

to pressure test your expansion tank and coolant system? it might be cheaper to take it to a shop if you only want to get one reading. the tool is free to rent from autozone but the bmw adaptor is at least $50.
