Nerih 0 Posted September 28, 2005 Report Share Posted September 28, 2005 right, fill up the the water bottle (and various pipes), have a BIIIG jug of water available, and turn on, LEAVE the expansion cap open (vw shouldve done this for u and checked or leaks when they did ur head gasket!!!), run the car squeezing the top radiator pipe, run for a while, ensure heating works.then if you have leaks from your expansion bottle, IDENTIFY them and RECTIFY them, there should be no leaks.a busted water pump will leak, check to see if its leaking, check to see if the pump pully is turning or if its wobbling. vw charge quite a bit for water pump replacement....mine needed changing at 75k (the vains were nearly all broken) Link to post Share on other sites
antera309 3 Posted September 28, 2005 Report Share Posted September 28, 2005 The water pump went on mine, and as Nerih says, I got water leaking out of the little "bypass" hole just underneath it. I also got loud squealing noises.The little hole at the top of the expansion tank is a pressure relief valve. It's designed to vent steam if the pressure in the coolant system gets too high. Typically this will happen:1. In an overheat situation2. When combustion gases are leaking into the coolant system, applying additional pressure (usually the fault of the headgasket)(2) is very unlikely in your case, since the headgasket has just been replaced!I'd try replacing the expansion tank anyway, 'cos it's a cheap part and easy to replace yourself.Replacement water pumps are actually a cheap part ( Link to post Share on other sites
petervr6 0 Posted September 28, 2005 Author Report Share Posted September 28, 2005 sorry guy didnt have the gasket done a a main stealer an idependant vw specialist so tolk the pump out today its ok it had a vw pump with plastic veins maybe a upgrade due to the problems with them anyway changed it any way also changed the thermostat only 37 for both parts and fitted my self. there is still a very slight trickle coming out so you reccommend changing the bottle then leaving the cap of and squezze the hose for how long also what is this for to bleed it or something. could the bottle be split on the inside because this should have no leaks at should it.

petervr6 0 Posted September 29, 2005 Author Report Share Posted September 29, 2005 out of the 2 holes you can see in the picture its the smaller hole Link to post Share on other sites
Nerih 0 Posted September 29, 2005 Report Share Posted September 29, 2005 on my vr6, the slat'ed hole has a sensor attached to it. the barbed connection goes to a water (overflow) pipe.squeezing the pipe removes any airlocks, and running with the bottleopen helps, just check if ur heating works m8.

petervr6 0 Posted September 29, 2005 Author Report Share Posted September 29, 2005 heating nice and hot any chance of some pics of other vr6 tanks then have i got something missing then Link to post Share on other sites

antera309 3 Posted September 30, 2005 Report Share Posted September 30, 2005 For those of you having to swap out your main water pump, I found this fantastic guide on the 'Vortex:Click here:http://forums.vwvortex.com/zerothread?id=1154344The guide is for the US Mk4 VR6, but the procedure is perfectly valid for a mk3 VR - all the important bits are the same.

petervr6 0 Posted September 30, 2005 Author Report Share Posted September 30, 2005 so are the mk4 v6 4 motion engines the same as a vr6 there not actually v6s Link to post Share on other sites
Nerih 0 Posted September 30, 2005 Report Share Posted September 30, 2005 they are 24v arent they. Link to post Share on other sites
antera309 3 Posted September 30, 2005 Report Share Posted September 30, 2005 In the US, the V6 version of the Mk4 had the 12v VR6 engine & 2wd transmission, straight out of the Mk3. The only differences are a different inlet manifold, engine covers & ECU map. This is generally referred to as the "OBD3" VR6 engine, but in reality it's just an OBD2 lump with the above mods.In Europe, we got the newer 24V engine & 4x4 6 speed transmission instead (Golf 4Motion). This is still a VR6 engine, with 15 degree vee angle, but has a slightly different engine block and a very different cylinder head. Link to post Share on other sites
VR6_Absy 0 Posted September 30, 2005 Report Share Posted September 30, 2005 I had similar problem with mine spitting out water from the expansion tank. I replaced the tank and cap, flushed out and refilled with G12+.I've spoken to a few VR6 owners who have had similar problems, stealers don't seem to have a clue but this cured it.guess it's an age thing with the VR Link to post Share on other sites
petervr6 0 Posted September 30, 2005 Author Report Share Posted September 30, 2005 sorry whats g12 ok so all thats left for me to do is change the bottle then as it has been flushed 3times when the head was done when the water pump was done and the thermostat Link to post Share on other sites
Justicevr6 0 Posted October 1, 2005 Report Share Posted October 1, 2005 G12 is the VW coolant it is ment to be the dogs bollo*ks to help keep the engine cool and help stop corrosion.It costs about Link to post Share on other sites
petervr6 0 Posted October 1, 2005 Author Report Share Posted October 1, 2005 might get some of that then flush it and change the bottle Link to post Share on other sites
antera309 3 Posted October 1, 2005 Report Share Posted October 1, 2005 G12 is the only coolant that VW main dealers sell now and is pink in colour. It doesn't mix with G11 or normal blue/green coolant so if you've got that in there, you have to flush it all out first. Link to post Share on other sites
mightyvr6 0 Posted October 1, 2005 Report Share Posted October 1, 2005 That's incorrect. Dealers sell G12+ (purple) which can be mixed with either G11 (blue/green) or G12(pink) safely. Link to post Share on other sites
antera309 3 Posted October 2, 2005 Report Share Posted October 2, 2005 Didn't know that! I coulda saved myself a bit of time flushing my coolant system! ah well... Link to post Share on other sites
