Gruven heater core T-connectors

[kbuskill]

Reading>me LOL

Some feedback from someone who's not ordered them, but might entertain the idea in the future:

- Smooth side is a turn off. It appears sized to fit the push to connect hose end, but without any provisions for actually securing it. Either add a barb for clamps, or add a lip for the stock heater hose. Feels half assed


- Cheap screw clamps aren't what I would expect for a product of this caliber. Either include spring clamps (preferred) or proper no-pinch hose clamps.

Agreed... I suggested the sleeved hose clamps to him. I also suggested the silicone hose, which he listened to me on... not sure why he didn't go with the sleeved clamps I suggested.

Again... I'm not certain why that side doesn't have a barb or anything. I will ask him but as I mentioned in the earlier post... its probably not really necessary due to the amount of hose slid over the metal and the low pressure that the system runs... but I agree, a barb wouldn't hurt my feelings.

Received my Gruven heater core T-connectors and Dorman Y-connector today...

Its gonna be next weekend before I can get them installed.

So I got these installed the other day...





After installing them and giving Paul, from Gruven, feedback on the fit and finish and because others on here have expressed concern over the fact that the one end doesn't have any barbs on it... I recommended to him that we add barbs to that end...

Here is a CAD drawing of the new design...


He will be sending me 2 more after he gets them done for some more R&D but I believe this will be the final design.

I also mentioned to him that some of you would prefer to see the spring style clamps instead of the worm gear style clamps.

I mentioned that due to the very limited space where these are installed that the spring style clamps might actually make the install easier.

He said he will check into them and see.

Just wanted to update this thread to keep you all in the loop.

Awesome thread, thanks for getting this done! Sick of the plastic cooling system parts. I installed mine with no issues. I see where a barb could be nice on that other end but i clamped it down and was fine. What hose clamps are you talking about with the spring on them ? Ive only ever used screw type, the ones supplied in the kit worked great and the blue silicone hose was nice.

They don't have a spring ON them, they are a spring style clamp.

Like these...


They are the style that GM uses from the factory.

And when used with the correct tool for installation, they’re easy to install. The pliers ratchet to hold the clamp open and also rotate so you can install them in difficult places.

INB4 anyone else asks for Ken to hook 'em up with the original design ones.

Worm gear hose clamps will tear those nice silicone hoses up

Yup. I still can’t believe a company like Gruven included those.
