3200 GT inled hoses and coolant drain

[Alecci]

Greetings,

I'm in the process of ordering some new silicone hoses for the engine bay as I will anyway be replacing the ones under the intake plenum when I replace my knocking sensors.

Looking into the engine bay I spotted some cracks in the inlet hoses going from the intercoolers to the Y-pipe in front of the throttle body. Figured I order a set of silicone ones to replace them with as well. Problem is I have no protractor with which to measure their angle (45 or 60 degree would be my guess), and since I'm everything but a mathematic genius I'm not to keen on calculating the angle after taking measurements. Does anyone know the angle of these inlet hoses? Inner diameter seems to be about 68 mm as measured from the ends of the Y-pipe.

Also, does anyone know where the drain plug for the coolant can be found? Thought I'd try to avoid soaking the engine in coolant when I remove the hoses under the intake plenum...

As always, any help would be much appreciated.

You might find it difficult to replace the turbo inlet hoses with silicone version's,it's a complicated moulding with the turbo pop-off valve flanged to the lower part of the hose.

Regarding draining the coolant, just pull off the lower radiator hose or the hose from the thermostat for a few seconds

I looked into replacing the two hoses but if I recall correctly they are different diameters at each end and neither 45 or 60 degrees so you cant order standard pipe - also length exceeds standard lengths. Consequently you need to find silicon hose manufacturer who has made a mould from a standard hose (early 3200). I have used Roose Motorsport for repalcement cooling hoses for my 3200 so may be worth checking with Paul there first. I think I read on the forum that someone was going to take a full set of air hoses to be made into moulds but cant find that thread at the moment - my bottom intercooler hoses are next to be done as perishing but may wait as again these are non symetrical tapered hoses so again a mould will need to be taken.
I dont think there is a drain for the cooling system - just have to undo a hose (thermostat) and collect in a bowl. Be careful removing hoses off radiator coupling as the pipes have been known to crack if not supported.
I have previously posted size of the hoses under the manifold but shout if you need me to find it - I recall there are 4No 60mm long.

Seems like a good idea to have a HPK fabricated then, as it seems much of the original design is far from ideal when performance is concerned.

I managed to find the topic you're both talking about, the coolant hoses under the manifold are 60 mm long and 32 mm in diameter.
