Fixing My Z4's Coolant Leak

[@itsjoel]

Cracked expansion tank. That happened to me twice on this car. I went through 3 of those tanks!

[@MattCalvert]

Haha yea it was a fun one to figure out. I wondered if it had been changed before. Definitely finding less bolts than expected to remove shoild have been a dead give away. 😂😂

Brilliant video. The plastic tray underneath my Z4 was just clipped on using gravity no bolts. The other smaller trays were broken Half the clips had fell off or were corroded in. Had to send it to shop 😔 for new rad. Keep on at it! Did LEJOG recently, it was seamless and days of fun.

Amazing video man I only have a problem that the transmission cooler keeps popping off and I don’t know why

[@MattCalvert]

Cheers man, but surely that is the thing with older cars though? Part of their charm so to say.

[@Andy182w]

That the best way to learn mate. Just get stuck in. Hopefully no more horror stories to be uncovered on the zed!

[@MattCalvert]

Hopefully not! And definitely learnt a lot from even doing this on the car.

Leaking where bracket connects to radiator? Argh. WTH. Cannot figure it out. Finally got everything else replaced and sealed and now. Pours out bottom

[@MattCalvert]

My problem was I needed to add an o-ring as some of these parts don’t always match up perfectly. But surely that is half the fun 😂

Hi what coolant did you use please

[@MattCalvert]

I let used the Halfords NAP free ready mix that their website advises. Nothing to exotic and odds still holding up brilliantly

[@toms_garage]

How’s z4 life treating you?

[@MattCalvert]

Well after servicing the coolant system my self it has survived a drive down to Monaco and been round the ring so I think it is going well. Still need to sort that headlight out 😂

[@toms_garage]

glad it survived that trip! I had an e85 years ago, great driving car@@MattCalvert
