Change broken radiator?

Omega B Caravan MV6 3.0 - Radiator Replacing Operation

Hi all, I wonder if someone can help me on this one. I need to change my old radiator from my 1998 omega which has the incoming plastic tube completely broken. Anyway, my main worries are the speed box cooling tubes attached to the old radiator and the aircon...

Should I prepare some kind of plug to seal the oil tubes?
Will I have to refill the gearbox level after replacement?
Is there any chance of gearbox damage when replacing the radiator?
What about the aircon radiator, is there any particular care?

Help needed...

Oil cooler pipes.......you`ll only lose a slight amount......when disconnected wrap a plastic bag or similar round each and secure with a cable tie or similar.
A/C condenser.........just take your time when lifting the radiator out

Just remove the hollow bolts from the 'banjo' fittings on the gearbox oil cooler pipes. Be careful you don't lose the copper washers (2 on each pipe) but you'll only lose a small amount of oil and so won't damage your gearbox at all. Thumbs Up!

You won't need to do anything with your air conditioning radiator (condenser) because it lives in front of the main engine radiator. Wink

What cares should I take with the aircon? Is there anything in particular like an hidden screw or something? Should I take the air inlet or no need for that?

Air intake is negligible.
Just make sure you don`t damage A/C condenser when removing rad.
No hidden screws, 3 electrical connectors on passenger side of radiator, two 8 or 10mm bolts either end of top of rad + the two inverted "U" spring clips on top corners.
No need to remove the "air inlet" (bagpipes)

Apr 2011 at 23:14 I'm looking for a new radiator... those with plastic covers are really fragile, in particularly the plastic tubes! What is your opinion about it? Anyway, when refitting the hoses can I apply any contact glue between the hose and the tube?

No. The gearbox isn't completely full of oil/ATF and any way there's a breather on top of the gearbox.

You don't need to do anything with the condenser if you are just replacing the main radiator.

Not really. Undecided

I take it you mean all the induction pipes Undecided

If so ..... Definitely! Thumbs Up!

Replacement radiator will also have the plastic sides, not ideal but that`s the way they`re designed. No contact adhesive necessary on the hoses or spigots. If you did that how would you remove them if one of them split. Decent pipe clips are more than adequate.

I stand corrected Although I *removed* the rad from the breaker with the bagpipes in situ

Because the last hose replaced by a mechanic costed me some extra money... the clip has stuck the hose... So OK, pipe-bags will remain in place unless i can't move my BIG hands lol...

Use the original sprung hose clips & preferably not Jubilee hose clips.
Remove the bagpipes, you'll not manage to do the job at all with them in place.
