Default Coolant fluid leak : 2 gallons every 7000 miles!!!!!!!!

No smell, no outside leak, look`s like oil is 100% clean from that so my BIG problem still is, where i could find the cause?

Default The red/orange residue is a pretty good leak detector....

I needed to replace my top Rad hose (~100.00USD). The expansion nip repair I tried was not good enough. There's really a lot of nipple considerations on these cars.

Default Have been noticing a similar issue in the past 2mos; have to top up the coolank reservoir

every 1-2 weeks. No overflow in the engine area, but have noticing a leak on the ground, so it's leaking from somewhere. Car is in for regular service next month, so I'll have them check this out.

Default Residue is dried coolant that leaves colored traces of where leak is...

Rad is short for radiator. The big hose near the top front of the engine. Look for a small hose that plugs into it at a fitting. That is the expansion tank hose. That fitting leaks after some time and the whole hose needs replacing.

Default Same thing happened to me - Radiator..

had a small hole in it. Leak was most pronounced while running the engine, so there were no puddles on the garage floor, etc.
