Where does the rebuild kit come from, BMW or others?

[tech71]

Yeah, why no info/plug on the vendor who supplied the kit??

He did mention that the kit came from Blunt.

Thanks for posting, great video! I’ve pulled mine before and don’t recall being as “happy” haha but like you mentioned, it is quite satisfying!

He says the kit came from Blunttech but didn't post a link ... All pretty easy to find from Blunt's website, though.

Thanks for making this, David. I definitely need to do this at some point and it feels more manageable now. Btw, where did the 1600ti end up? I think you said in a Youtube comment that it sold, but did it stay in Canada?

Bluntech:

Rebuild kit - https://www.blunttech.com/shop/replacement-parts/climate-control/heater/1355btkt

He also used the valve mount repair kit - https://www.blunttech.com/shop/replacement-parts/climate-control/heater/1356btkt

 

 

PRD has this stuff too. I've never ordered from them so can't vouch:

Rebuild kit: https://prdesignsf.com/shop?olsPage=products%2Fheater-box-rebuild-kit

Mount repair kit: https://prdesignsf.com/shop?olsPage=products%2Fheater-valve-mount-reinforcement-kit&page=1

Its a good, useful vid but hardly ground breaking, comprehensive instruction exists right here on the FAQ.

The Blunt Tech kit is great, saves a ton of time and scrounging, well worth the cost.

The most painful part is the cost for a new core/ fan motor if required, I needed both.

Dont reinstall your old core unless you are certain its serviceable (pressure test)

Dont use rivets to resemble, use readily available hardware( washer head bolts. self lock nuts) from Ace/Home Depot.

Reduces the probability of cracking the aged plastic😉

Dont over tighten

Tech71 is correct:  "Don't use rivets to resemble, use readily available hardware( washer head bolts. self lock nuts) from Ace/Home Depot." 

 

Here are No-Rivet options a la Ace Hardware to connect the two halves..

 

Round-head Bolts (photos 1 and 2) bolts, washers, and nuts and brass Flat V-Head (photos 3, 4, and 5) bolts, washers, and nuts.

 

Round Heads:  They are proud so you need to build up the gasket/sealer material a little so the box surface sits flush.

 

V-Heads:  Can be made to sit flush.  Use some sort of angled scraper, sharp digger, handheld drill bit (DO NOT use a drill!), etc. to CAREFULLY, CAREFULLY, CAREFULLY make a V inset (photo 5) around the hole into which the V head will sit.  These are not proud, so no sealer build-up needed.  

 

Both work well.

FLAT V HEAD

I really enjoy your videos and was wondering if you were also on the faq.  Great to see that you are! 
 

Will be sure to watch and add this project to the list…

If pop rivet washers are used on the back side, the rivet expands beyond the washer, not in the plastic.

Great video David and perfect timing! I'm doing this same job this weekend. Have the rebuild kit and ready to go...

I do have a couple cracks in the case though. 
Any recommendations on how to fix those?

 

Thanks!
