Bypass Coolant filter leak

[dmausel]

Dieselsite model purchased this past summer. So the T fitting on the heater hose leaks when it's cold at night. I've re-tightened it, moved the hose clamps slightly, but still a puddle in the driveway in the morning. Any suggestions?

Since it doesn't say otherwise in your signature, are you sure it's the by-pass and not the EGR cooler? My mystery winter puddle was the EGR cooler leaking from that crappy OEM hose clamp. A delete kit fixed it.

I can see and feel the coolant right at the T fitting. I'll have to look at that egr hose too when it's light out

If it is the T fitting then you could always considering replacing the hoses with the hose kit from PMM.

There is an updated T fitting the kicker is they will charge you more than the T is worth don't ask how i know. I have there boots also $200+ and some are coming apart i will never send anyone there again i missed one steel ring where a 44 cent stamp would have worked but they charged me $12 shipping what a deal never again.

Sorry 'bout that. So there's an updated fitting from dieselsite? I looked but didn't see the part listed for sale.

Is it the fitting it self, or is it the connections to the hose? Tephlon tape it and see if that helps.

It's the hose and fitting connection. Will try a bigger hose clamp over the barb and snug it up. Hope that works. If not then a new fitting is in order or maybe adding some Teflon tape as suggested
