Dieselsite coolant filter warning/fix (with pics)
 

Hey guys, I recently had a problem with my Dieselsite coolant filter. I had a little problem that caused me to loose a lot of coolant and make a huge mess of things. The heater hose T-fitting is obviously spun on a lathe as well as the barb but the problem is that the 3/8 barb fitting is simply press-fit into the main tube. Which when under pressure caused the barbed portion to pop out and dump super-heated coolant all over everything. I fixed it by simply drilling (8.5mm) and taping (1/8NPT 3/8) hose barb in it's place and it's now it's good to go, for good. Anyway, I figured you guys would like to know of a potential source of a sudden coolant drain. Here's the pics.

Not yet I was going to call him today but got stuck hanging X-mas lights, will do tomorrow though.

they seemed like pretty good guys to deal with. i think they will make it right with you and i am sure that they would like to know if they have a defective part. i know i will be watching mine now. thanks for the heads up.

How long ago did you buy your coolant kit?
I bought mine 2 months ago, I will check mine tomorrow AM in daylight!

Thanks for the heads up!

Me too ... It was one of those HELP Plastic Heater Hose Tee's (3/4"x3/8"x3/4")

I got mine mid/late October so about 2 months ago too but I didn't install mine until about 2-3 weeks ago. Give the 3/8 line a little pull/twist hopefully yours will be in there strong, if not it's an easy fix so no big deal if it pops out in your driveway but on the road you're totally screwed.

Same thing happened to me with the same kit about 8 months ago. I couldn't believe how cheap of a T it was. I went to car quest and a new plastic T.

I wonder if they will follow through with fixing "THEIR PRODUCT".

Thanks for the post.
I will keep an eye on mine :)

I made my own, so I was in charge of quality control. I used copper fittings.:-dancing1

wow what a pile of junk. glad i didnt get one.

mine is leaking a little bit.

High Binder. You should let diesel site know of this post.

I used a 1"X1/2 pex plumbing tee, you can get this at any plumbing supply store. the other tee is just a straight 1/2 pex tee. they are made of brass, they will last for ever. I would never use anything else. vangard is one maker of the pex tee. don't go to home depot type plumbing stores, they have them, but may not know what you are looking for. good luck, my is working fine.
