am i missing something? ive seen some cars which have another pipe coming from the side by the cap.

 

 

when i installed the rad, i just had the 2 main pipes which go to the engine, and then 1 pipe at the bottom which goes to the expansion tank

Is that for a overflow pipe???

 

i wouldnt have thaught so, as the expansion tank does this (think)

 

????????

 

yea, at the bottom of the radiator, there is a take off, which connects to the expansion tank. this is the only pipe which connects the rad to the expansion tank

you have a plastic pipe broken off there....that should go to the overflow bottle !

 

Lower down pipes are for Oil cooler, and are not connected to the radiator core.

ahh,

 

so at the moment my expansion tank is doing nothing,

 

can you elabarate on the take-off at the bottom of the radiator more?

 

why would the oil cooler pipes conenct to the rad? (know you say not to the core/inside)

Some zed's have the oil cooler as part of but separate to the radiator. Essentially two rads for the price of one.

because they are a kinda "heat exchanger" and a sealed unit within the rad..the heat is soaked away by the coolant within the rad

ive defo got a radiator & oil cooler seperate.

 

but also the take-off on the rad. can i just block off the rad then at the bottom?

 

 

 

(will conect the hole at the top to the expansion)

You can just diconnect/block off the oil cooler pipes if you have a seperate oil cooler.

 

You'll need to repair the rad somehow to fix the expansion pipe to it, as its snapped off. Would be best to replace rad.

 

What is should look like :

thanks for that pic dude.

 

 

il see if i can fit some sort of prong through the hole and seal it, then run it to the tank.

 

 

whats the harm if dont conect the expansion tank? isit the steam from the rad has nowhere to go, hence pressurizing?

 

therefore the steam goes to the tank to save the rad?

no you need the tank as when the coolant has cooled it causes a vacume in the rad and the coolant gets syhoned
