I think I may have been saved by my new DIS I had fitted by Timmus!
so, during my recent 1600mile trip up North, I have had to top up the coolant on Chad, no obvious leaks except it was wet around the expansion tank and there was coolant on the top of the gearbox. Once topped up it would last a couple of days before refilling. Strangely I have never had a low coolant warning come up??
so yesterday I was off to Aberdare to pick up some bits from Steve ( Thanks Steve Edwards) then to Newport for a party……taking the caravan to stay over. As I was heading up the A46 out of Bath, I remembered I’d not topped up the water, so I select the coolant temp on the display ….which went up to 104 degrees, at which point the dashboard temperature crept just past 90. I pulled over and could see steam, and it turned out to be a pin hole in the bottom hose to the oil cooler, which squirted a jet of water up to the header!!
Not wanting to miss a party, I called home and had some bodgery bits bought to me, and I cut both pipes at the cooler and capped them off, a bit drastic but needs must etc!!
Needless to say, it was fine after and used no more water.
Today I went to replace the hoses with some silicone , and was shocked when I got to see the top of the hoses at the cylinder head, these are hidden behind a steel plate and the engine cover, and cant be seen easily, how the hell these have stayed together and not popped is a miracle, literally just mush, yet the rest is ok.
All fixed now, 19mm silicone hose cut to length works fine, the only thing to watch it that neither hose fouls the gear selector cables.
I used jubilee clips as the silicone is thicker wall so the original clips wouldn’t fit. I advise anyone with a tdi to check their hoses!!!
