Are the metal parts the ones that are sandwiched in-between the grp, at the bottom where the support stays bolt through??

One of mine is 'swelled and rusting the other is fine.

[Mightymetro]

This is the part I was talking about

[Barrykearley]

Time to get the anglegrinder out, some flap pads, a spot of new steel and a pack of grp from Halfords 👍

[Mightymetro]

Is it made from 2 pieces of fibreglass and then bonded together over the steel.  I found these from SJ and I guess they are like repair parts ?

Make your own out of stainless and glass them in chap - it’s easier than you may think

[Mightymetro]

Thanks Barry, so grind one layer of glass away to remove the old part and then lay over the new fabricated part?  I’ve never tried fibreglass repairs.  Well......I did once when I crashed my bike at Cadwell...........fairing came off in the collecting area so maybe I need to practice 😂

[Barrykearley]

Yes - just make sure the rust and rubbish is all gone - use wood or cardboard to create a backing to glass onto - and use the flap pad to grind it into shape after.

Some pics to help. (OK it is an SE)

Some threaded rods / nuts and washers make an excellent lifting device.

 

 

[fjmuurling]

Undertray rusty brackets. Be creative with some stainless steel, cobalt drills and grinding tools, and some epoxy and glassfibre. I also made a jig first.

 

[Mightymetro]

That’s fantastic help, thank you 

[fjmuurling]

I covered the jig with self adhesive foil used for protecting the covers of books (in dutch boeklon / kaftfolie). It is cheap and more important the epoxy doesn't adhere to it.

If you need more pictures just let me know.

I went down to Serck Motorsport in Hayes yesterday. They are doing my rad with a 3 core and fitting some Spal fans.

very impressed and I got a pretty good deal so Im happy.

Just gotta repair the tray now. perfect timing for Freek to post up those pics.

Oh and a whole load of Stainless nuts and bolts turned up in the post today.

Thanks

[Mightymetro]

Are they fitting the fans directly to the rad frame Andy or fitting them in the cowl ?

[andyblackman777]

Like this. 

[Chillidoggy]

That looks just like the job Serck did for me.

Yes that is your pic! I’ve been following your thread with great interest. 

[Chillidoggy]

Good grief, I didn’t recognise my own bloody doorstep! Must be old age creeping up on me!

Yes, Serck did a great job for me, the old guy Roy? Ray? was really clued up. Highly recommended.

On the subject of cooling.

Does the V8 really hold 15 litres of coolant. I've never managed to drain even close to that amount out??

Andy

[Chillidoggy]

The 4-cyl holds 24 litres according to my handbook.

Most of that has ended up on my garage floor at some point.

[MD355]

It's weird, on the Owner's manual of my Lotus Esprit V8, in the capacities section (page 103) it says :

Cooling System    - 4 cylinder  : 24 liters

                                -  V8              : 15 liters

This is crazy !!! That's why V8 cars overheat !! I guess the 4 cylinder cars have the charge cooler system, but still...

 

[andyblackman777]

is the chargecooler a separate system??

[mike_sekinger]

yes.....

[andyblackman777]

I want to know where my remaining 5 litres is? I only got 9 out and about a litre on the floor

Wow so 24 litres in the S4!

[mike_sekinger]

I would expect that the heater circuit contains a reasonable amount.
