Hi guy's,
My Treg cooling system has succumb to the dredded plastic rot all VW's seem to suffer with.
Last night the pipe which goes around from just behind the HP pump, then behind the alternator, under the exhaust manifold, behind the engine mount and onto the rear split.
I need help identifying the part so i can source one.
The car is a BKS engine, VIN WVGZZZ7LZ8D029158. JXX gearbox.
Does anyone have access to ETKA and could find the part.
Well that's been fun---its not plastic rot--it seems VW have installed metal connections onto the engine (Thank F!%K for that) and the pipe which has failed is the fist example of bad workmanship from the manufacturing division whom make pipes.
The pipe is 059121075 and looks to have had a hole blown in it when a nozzle was welded on and its been filled with Paint. The paint has lasted 12 years and just let go last night. Removing the engine mount was real fun it took 4 hrs to get it out.
Anyway its out and generally looks in great nick other than the hole.
Hmmm... Apologies the 1stVW site did not pan out. It is possible that they could be limited to North America Models. The site is ran by an actual VW dealer.
Drag mentions Ektacc which google links to www.oemepc.com.
What is the repair plan? Replace or get the existing metal pipe fixed?
One of the steps off Erwin says 'remove the 4 bolts and 1 nut then lift the engine mount bracket off the mount'
It should have said 'after solving world peace simply.....'
The engine does not have to come out, i had to make a spreader beam to hold the corner of the engine up about 25mm so the engine mount could come out, the engine is still connected the opposite side and at the gearbox:
On the 2nd picture where you can see the four mounting faces on the (Black dirty) engine mount, the slot between the 4 points is the path the coolant line runs through, and as the line has crimped on ends and a tee piece there is no way it will come through so the mount has to come out.
Follow up, the pipe is $500 from VW which is steep so say the least, so being in the engineering background, i took it to work where we wire stripped it clean of paint, thickness tested it and found on the tightest elbows the metal was thin 0.3-0.5 so we have built up all the elbows with a large pad of high grade silver solder (56% silver). The pipe has been primed and repainted and looks good
Re-assembled the car last night and filled it with coolant. Next i made a makeshift belt that fitted on the engine coolant pump pulley, using my makeshift belt being driven by a battery drill, you could hear the air bubbles working their way back to the expansion bottle---2.3L of air came out using this method.
That engine mount is a doozie. Once assembled i throttled down my compressor to about 10-15psi and pressurised the cooling system. Locked off my air filling hose off (Trusty vice grips) leaving the system pressurised and it has not lost a single pound overnight.
Now i'm just waiting for new idlers for the aux belt which should be here next week and we're good to go.
if anyone needs more details don't hesitate to PM me or ask on here.
