3 Radiator / Cooling system Caps ?!

Recommended Posts

Hi Everyone

 

I own a '93 Ford TX5, which has the same engine as a MX6 or 626 with the 2.5V6 engine.

 

KL engine

Please have a look at the picture. There's 3 places one can add water/cooling solution to the radiator system.

 

Can anyone kindly explain to me which each one's purpose is please?

 

 

 


Thank you.

#1: this is where you normally top up the coolant if it's a little bit low in the plastic reservoir bottle.

But if the coolant level gets very low, so there's air in the cooling system (this will only happen if there's a big leak, or you drained the coolant for some reason, or you neglected to check coolant level in the plastic reservoir bottle #1 for a very long time), let the engine cool down, then open caps #2 and #3, pour new coolant into #3 until it's full, then add a little to #2 until it's full too.

#3 exists because it would take forever to refill the coolant using #2 only. And #2 exists because you would get an air bubble at the top of the radiator if you refilled the coolant using #3 only.
