Lowering Engine/Coolant tank change/911/996 - 2003

Recommended Posts

I have decided to change the coolant tank after discovering a small leak in the pressure relief valve housing. I can see that there is not much space and know that I'll need to remove the SAI motor and the main air intake. On reading various posts I see that lowering the engine is a good option for getting extra space around the tank.

I have had a look around the engine bay and it seems that most stuff will come down an inch or two with the engine when the two rear mounting nuts are released from the studs. I am hoping this will give me enough space to get the tank both out and in.

My questions are:

1. I will take the hoses and level wire off the coolant tank before I lower the engine, so are there any other hoses or pipes that are likely to have any bodywork ties that will become over stretched or broken as a result of this lowering?

2. Will lowering the engine give sufficient space? I have heard that some people also take off the fuel supply line.

I am not intending to drain the cooling system. I will just empty the coolant header with a siphon tube, leaving most of the coolant in the system.

Look forward to replies.
