Thread: D2 Td5 Radiator to Expansion Tank Line.

Has anyone heard of doing this? I think the best think to do is to return it to the factory set up.

Hi Ben , Probably because that stupid brittle plastic hose was broken so the blanked it off due to price. You can just go to repco or a bursens etc and get a rubber hose that diameter and fit that.

An important part of the system, the radiator bleed pipe & hose. From RAVE;
" Excess coolant created by heat expansion is returned to the expansion tank from the radiator bleed pipe at the top of the radiator. An outlet pipe is connected into the coolant pump feed hose & replaces the coolant displaced by heat expansion into the system when the engine is cool "

Can you find out how long the pipe has been blocked off, can not have been doing the system any good. That hose hardens up from the heat, & cracks. Just a tip, check the secret hose, from the oil cooler, another hose that is effected by heat. Bob
