When I had the Astra V6 out and about last month I had a couple of occurrences of the dreaded click click before the starter engaged and the engine fired up. I’ve never had this previously but it’s a sure sign the starter wasn’t happy. My intention was to get the original Bosch refurbished but found a reman with 5 year warranty cheap as chips so bough it. Next mission was to replace the starter which isn’t easy on the V6 lump with tech docs saying remove this that and the other before even reaching the starter. I fortunately only had to remove the drive shaft and intermediate shaft.
I made a bung to hold the gearbox oil back using a socket/bag/tape and didn’t lose a drop.
After a wrestle, some mumbling followed by swearing the old (dodgy) starter was off.
Old meet swanky new starter.
On it goes and assembly is reversal of disassembly. Issue resolved and the starter is working flawlessly as expected.
I also noted a split in the intake hose from the airbox to the MAF (Mass Air Flow sensor).
While removing this damage I also found a split in the hose from the MAF to TB (Throttle Body) but I had a good used undamaged spare on my shelf so this was an easy fit.
Back to the pre MAF hose I investigated a few options but a generic silicone hose was simply too tight due to thick hose walls to fit with a clip to the airbox.
I wasn’t able to source a new OE replacement anywhere so I simply used 50mm wide insulation tape and wrapped the damaged hose. As you can see it looks great and is fully sealed, you wouldn't know if I hadn't told you. Yes, I’m aware Roose sell a silicone kit with both hoses
here but I really wanted to retain the original so my solution made sense to me.
