Radiator query
norfolkluego - 18/6/08 at 06:25 PM

Hi everyone, new to the Forum so please be gentle with me!
My Luego is overheating, I suspect the water pump but the radiator looks pretty crappy as well so to be safe I'm changing them both. Trouble is I know what donor car the engine came from, Mark 2 Escort, so I can get a new water pump easily enoungh but the radiator certainly didn't come from an Escort. It's about 51cm tall and about 43cm wide. The hot inlet is on the back of the radiator, top left (as looked at from the back), cool outlet on the back bottom right. Any ideas what it may have come out of or suggestions for a replacement.
Cheers

As above, there's a company on the Bay that does ally ones for about £30 or so. Best go with an early one which may also be listed as for a VW Derby

I was at the scrappies the other day and had a look at a VW Corrado (think it was just a 16v'er) and the radiator looked as though is would fit perfectly in the nose of a seven-type car.

I had a Golf rad on when crossflow-powered , since replaced with a Polo rad and a V6 (and never a cooling problem)

Identify the most likely cause of the overheating first ---- on old style engines like the xflo the water pump is the most unlikely cause unless it is leaking, this can be easy enough to spot.
If no leaks are visible the first thing to change or test is the thermostat.

Also check radiator isnt blocked.

When engine is warm (thermostat open if its not faulty) then you should have warmth all over rad, that gets cooler towards the bottom.

If there is a cold spot then that might be the block.

Radiator could also be from a Nissan Micra, that's what I'm using.

Overheating could also be due to an airlock in the system. Crossflows can be a bit prone to this in a seven.

Thanks for the help guys.
It's not the thermostat as I took that out altogether when the overheating started (although it was stuck firmly shut). The water pump isn't leaking but it's a cheap change anyway (£25 off Ebay brand new).
Rad looks old and scabby and no idea of it's history so I suspect that's the problem, I'll try and post a couple of pics of it tomorrow.
Thanks again.
