Whilst you may have read horror stories of it cracking, I’ve not heard one single instance on here.
I even asked the question about 18 months ago, and the answer came back negaitve.
To my knowledge, no one else has encountered the problem either.
Considering yours is about 14 years old, if you really wanted to replace it, fit an OEM one safe in the knowledge it will likely last 14 years.
I agree with the above. The alloy tanks are nice for a bit of bling but unless my physics knowledge is sorely lacking are probably radiating much more heat into the engine compartment.
Failures seem to be more common on US forums where the cars generally attain higher mileages and ambient temps are hotter.
I changed mine when I bought the car last year ,was it nesesary I don’t know but it gave me peace of mind .I just swapped it for another OEM one. For the amount we use the car , I figured it should be good for another 10 years or so.
I’ve since removed the shiny label (dental-floss saw on the D/S tape and white spirit to remove the sticky residue).
There are oddities about the Davefab, such as the orientation of the overflow spigot and the angle of the pressure cap. On the plus side it has excellent welding and a sight glass at the correct level.
Yes it is the IL and no it is not easy to check the level.
Obviously i have to check when cold and look into the tank and if it appears to be 2/3rds full i am happy with it, I keep meaning to make a dipstick of some kind, possibly a wooden lolly pop stick or similar.
That’s the down fall of it.
IL Motorsport one for me too. I have a clear plastic tube marked at the correct level which I dip into the tank, cover the top with my finger and bring it out. Shows the amount perfectly and I then just drop the fluid back into the tank.
