Hi,

I want to replace the coolant liquid (thp 200), but I dont find the 2 screws to remove the air.
Anyone can explain to me or maybe has fotos?

Hi. I've got a THP156 and one of the bleed screws is in the top of the coolant outlet housing (which contains the thermostat). It's a plastic hexagonal screw with a cross cut into it. You will see it next to the temp sensor in the top centre of the photo. I believe there's another bleed screw but I didn't find it. It should be at a high point somewhere. My engine is different to yours but at least it might give you an idea of what you're looking for!

I think you might not need to use the bleed screws anyway. It might be that the coolant will find its way round the system without any problems. I didn't bleed my system at all. Cheers. Bruce.

Hi Bruce,

thanks for your fast answer. I check, and I saw the same screw.
