evoblade 0 Posted December 30, 2003 My 1994 VR6 has been loosing coolant from the header tank over the last 3 weeks. The header tank would run dry after about 500 miles. there is no water in the oil and visible signs of water leaking in the engine bay. Have checked pump and hoses and all are ok. I jacked the car up on the drivers side this morning so that it was leaning at about 30 degrees and ran the engine up. At full temperature a small jet of water was visible from under the coil pack. can anyone help with what this could be? :shock: Quote Share this post Link to post Share on other sites
vr6storm 0 Posted December 30, 2003 might be the aux.coolant pump leaking or the thermostat housing.............both are near to the coil-pack Quote Share this post Link to post Share on other sites
evoblade 0 Posted December 30, 2003 Cheers for the reply. Are they easy parts to get to? Someone told me that one of these parts is plastic and is notorious for failing. Is this the thermostat housing or the pump housing Quote Share this post Link to post Share on other sites
stu 0 Posted December 30, 2003 The thermostat housing is plastic, and gets brittle with heat and age. To get to it, take the plastic engine cover off, remove the coilpack, and the three coolant pipes. Once all these are off, it should become clear. It's held on with 3 allen key bolts. And I think the housing is about £22 from VW. Good Luck! Quote Share this post Link to post Share on other sites
