Monaro heater hose relocation?

[L2VXR]

I know there's always been an issue with them rubbing on the back of the head and I've regularly checked them and cable tied them back however they still seem to have worked there way back on to the head.This route just strikes me as being to busy and tight for all the pipes going through it
I spotted this whilst installing my headers


So has anybody relocated the hoses?
I was thinking of using two new lengths of hose routed up over the servo close to the bulkhead then back down between the inner wing and the servo connected back to the valve on the chassis, but would this cause issues with bleeding the system because of the hoses going up above the height of the block and the heater matrix ? would fitting a couple of inline bleed screws at the highest point solve this if it was a problem?

Whats your thoughts?

Just checked mine and even though it seems to have been fitted with a black plastic mesh protective sleeve it's starting to fray at that point.

If you have a section of pipe higher than the header tank you may get some air at that point, which may be a pain to bleed - but so long as you get the air out and with it being a sealed system shouldn't be too bad.

Surprised something hasn't been designed to clip to the bulkhead just to pull the pipe back a fraction, or maybe even a slightly longer pipe and longer bend to straighten/angle away the section by the head. Possibly an option for a silicon hose replacement?

Will have a nosey around mine later and see where I could put a cable tie or something - although if that's too tight it will end up digging into the pipe as well....

I've been looking at this too for a different reason, one of tidyness, and thought of the same route as you.

I've seen it mentioned on ls1gto that if you trim the hose it pulls it a bit closer to the firewall, not sure of that one myself.

It is extremely crowded in that corner, that side in general really. This looks very nice, but would presumably be EXPENSIVE.

A hydro boost unit? Looks impressive, and a lot more compact/neater than a big brake booster canister. Still - this is hooked into the power steering and given that I've already had to replace the power steering pump and front cooling pipes (because they rusted through and leaked) not sure I would trust my brakes to the circuit too... :P

Is it likely to be expensive though...

[SturdyHSV]

Appears to have an accumulator to allow about 3 applications of the brake pedal in the event of engine stall or some sort of failure, so not dissimilar to a vacuum assist.

They're apparently OEM equipment on a smattering of vehicles.

I've emailed them to ask, there's a universal kit that looks to be $400, so hopefully they won't take the piss too much with the 'GTO' specific kit.

They then have finishing options, machined aluminium, chromed, as is etc. but for ultimate cheapness that looks like about what it costs.

There's no point getting their 6' of PS line etc. as we're going to have some fun routing lines round to the PS pump / steering rack given we're RHD, so will probably need to measure up and sort out our own braided hose.

If somewhere is making contact with no easy fix, just sleeve it with another bit of rubber and cable tie it.

Well after a bit of wriggling I've managed to get the hoses behind the clutch pipe instead of in front of it so instead of the pipe pushing the hoses towards the cylinder head it now holds them well clear. The hoses are a nice fit in there not tight or squashed at all as if they should have been there from the factory but they couldn't be bothered to thread them through. I also trimmed about an inch of the lower of the two hoses where they attach to the bulkhead as this also improved the fit. Once I've finishes fitting the headers and im happy that the hoses can stay there I'll replace them with a new set for piece of mind

I was looking at my heater/coolant hoses again on mine and thought of the same thing - seems to be space behind the hard pipe (from the clutch master cylinder I think?) to route the coolant hoses. No idea why they haven't used this space themselves?

The only thing I could spot that might be an "issue" is that I believe the steering column passes below there, so if the pipes drop they will be rubbing against it. Was going to check clearances etc and see if this is likely to happen.

Plan to get some silicon hoses for the radiator to address another potential rubbing issue (but only because I've got an aftermarket rad and still using stock fans) so looking to do a full drain soon anyway - which will also allow me to sort out the heater hoses.

Yes your correct I was going to update this that on first impression once I had the steering nuckle back in place they did look close however I've fitted the new replacement hoses now and with a couple of sensibly placed cable ties I still think this is a better route for the pipes to take and there's plenty of room around the moving parts of the steering column .
