I already did the inline thermostat mod. I thought you were talking about using a copper or other metal hose instead of the thin hard line going from exp. tank to engine. Didn't realize it was all on Amazon tho. Did you use the BMW hose or a hosetechniques hose? Just curious.

 

I'm running the same temps in my D2. My D1 is lower. 180 t-stat in the D2. 160 as you know in the D1. May go higher in the D1 to get better gas (and save on engine wear?).

How are you not always in hot water when you have this SWMBO?

 

Did not know you were referring to expansion tank hose.

I ordered H.T. hose for that. Don't see the point in replacing a stock pos with another stock pos. No need for copper, silicone will hold up better under heat and stay flexible. Hard lines + vibration and heat swings to me spell trouble.

I think it was the 3/16" I D.

I guess you could always do a combo of copper and HT hose, but again, small mod, didn't see the point. Plus the locals around me can smell unguarded copper from a mile away, like hyenas....

 

...the local around me....ha. copper eating zombies huh. here too.

that's why i asked...replacing POS with POS, etc.

so, what, you got the 5/16 and then routed it around the other hoses with zip ties or stays of some sort. i'd love to see a pic of your engine bay.

mine's a blue pit water dog. you'd be impressed with her ocean/wave retrieval abilities. she does rats and lizards too but can't catch a live bird for sure.

 

I'll try to get a pic up this weekend if I remember for that hose. It was part of another fix I did. I'll have it exposed again when I get my parts for the inline therm mod and get a picture snapped with the 'ol iPhone.

And yes, beware the copper-eating zombies. Apparently it's going around.

Mine does a lot better on birds after I slow them down with a load of #4's - she's one of our retrieval dogs on the yearly pheasant hunt.

Does pretty well in the water as well. Not too dangerous unless you are a pheasant, the UPS/fedex guy, or something falling off the grill out back when I'm cooking.

 

OK...this cracked t connector led me to the in-line t-stat which I did and am liking the results. BUT, one of you guys said it can create additional leaks which it did. But I'm not giving up.

My temps are great at 180-190 in hot weather so can't argue that. But I am losing fluid and as I know - and as Mike said - I need to do a pressure test.

I wanted to rid all leaks myself first and I'm narrowing it down by eliminating the crusty throttle body heater plate, replacing the old hard plastic lines which were crumbling in my hands and cleaning all areas to check for other leaks.

Truck was still losing liquid although pretty sure it's less and less. No overheat, no white smoke so I got that going for me.

After a good run yesterday, no apparent leaks...maybe an inch of liquid loss but again no bleeding done yet.

This morning I found some liquid on the hose of the inline. It's a repeat spot so maybe I found my last leak. Problem is the hose that I put is about a 90 degrees being bent to maybe 75 degrees. In my opinion I should change this hose. So now, if I can I need to find a 75ish degree hose that fits.

Arrow shows where the buildup of coolant is and line is the hardline coolant tube replacement and elimination of throttle body heater.

 

Maybe I need a flexible coolant hose....

 

summitracing.com also has flex coolant hoses, and free shipping at the moment. Not that it's necessary with a rover, but I do like the braided steel ones.

Based on where the buildup is, it would seem that the leak would be coming from the sending unit (glowshift part) or the hose going to it.

 

A stop at a Summit store, like the one just south of Atlanta on the freeway, is always fun - lots on display where you can look it over. A great "pit stop" in your travels, even if not buying anything today...

 

I'd love to stop by....

There's seriously a lot of ho's there.

Hard to choose just one. Also a little difficult. Need to figure out what this -AN size means and which ones I can cut to size length.

But, I think you are correct ATL....the last leak should be coming from one of those three connection spots. Thing is that I would expect to see some color or crud of sorts at the connection, which I have not been able to find. I'll pull it apart, tighten the t-stat holder and redo the clamps. Even clamps aren't too easy for the inexperienced. The clamps are how I got into this mess...over tightening the clamps on the t-piece. But if I fix this it'll all be worth it as my temps are just great and steady. 180-190 even after my 2 x 1 hr drives yesterday...about the longest distance I ever do really.
