Radiator Cap

[simonknee]

Hi all,

Got a lovely recore of the rad by Serck.
They collected, delivered and uprated to 3-core with a nice lick of paint for ?130 all in less than 48-hours.

A replacement cap was supplied rated at 15psi, my old one is 10psi.
Are there any practical differences I can expect between them.

I don't run an expansion tank.

Generally the higher the pressure the higher the boiling point. I have a 13psi fitted to my S4 with no problems.

Don't forget to put in the anti-freeze

Where did you go to get serck to do your rad Simon?

They are a real bugger to find because they are a small part of the Unipart monster. You are looking for Serck Intertruck. I called a branch somewhere up north, who directed me to st albans branch, who passed me on to enfield. They're EVERYWHERE!!!! (but you wouldn't know it. Use yell.co.uk to find in your area.

It really is a top notch job (and I bet it's who all the garages use too)

What are the possible disadvantages to a higher boiling point?

[flyinggellyfish]

I had both my rads , present and spare , recored by a local firm for ?70 each . This included a modern type core and an extra row .

Try your local rad repairer in Yellow Pages . Paying cash always seems to help !

The only downside I can think of would be that it puts a little more pressure on what some consider to be marginal waterpump seals.

Just a thought...

I'll have to agree with jopalm. Any weak point in the system will see failure but that's only if something else fails and, as a result, you're seeing much higher temps, close to overheating.
