i am having a problem with my 306td,it seems to be over pressurising in the coolant pipes i think from drawing in air i dont think its a gasket fault as its brand new.

Air blowing into cooling system = blown head gasket.

If you're getting excess coolant pressure and it's not actually boiling at the time, then suspect a cracked head. The turbo versions of the [pre-HDi] Peugeot lump are depressingly prone to cracking the head behind the pre-combustion chamber at anywhere from 50,000 miles upwards.

A good head-shop can pressure test the head to confirm it.

If you haven't already; remove the thermostat and carry out one road-test to see if it makes a difference. If it does, replace it; don't drive it far without a stat fitted.

it dooesn't make any difference without thermostat.

What about the rad, have you had it checked it for being blocked.

Excessive pressure in the cooling system on these usually means that combustion gases from the engine are being forced into the cooling system as a result of either a blown head gasket or a cracked head. Try flushing the cooling system through to rule out a blocked radiator and then refilling it. If no change, take it back to whoever did the head gasket. These old XUD engines are notorious for this kind of failure, which can ruin an otherwise brilliant engine.

You can clean the system with Rad flush or whatever, but don't rely on this thinking the rad will be ok.

If the rad is really blocked that bad, then off the shelf stuff will not do the job. You'll either have to get a replacement or get a specialist to clean if for you.

Get a specialist to check it for you, first to rule the rad out from your problems.
