I can't remove the rear nearside wheel arch liner because the screws are rusted firmly in place. Can someone tell me how to solve the problem please? I've tried the usual unlocking sprays for seized metals without luck. Thanks all.

I used an angle grinder to take the head off then replaced the rivnut. I'd now use big-head fasteners instead. When grinding the heads off you need to spray them occasionally with water to cool them or they melt through the liner. Take care!

i got mine off the other day using vice grips got them on very tight and just turned them. the inside bit of the bolt just rounded off when i tried to remove them normally

Thanks for the replies. Are you suggesting I install rivnuts in the holes the rusted screws currently occupy or drill new holes to set them in?

In the current holes And consider the use of stainless steel fasteners with copious amounts of copper grease when refitting

Okay. I've not seem my car in 6 months so can't remember what holds the wheel arch liner on but, assuming I cut the heads off the screws that are, should I then be able to prize out the rest of the screw using mole grips or will it likely require drilling out?

As I recall, for the front the only bolts are the ones at the rear, the front 3 are plastic. If you cut or grind the heads off (without melting the plastic ) the metal scrivets are probably rusted in the fibreglass. If you tap what's left of the screw in to the bodywork, it should loosen the scrivet, and eventually you should be able to waggle it out. I replaced any that were unusable with the rubber scrivet things off eBay and used Allen head stainless bolts with some stainless penny washers, along with copper grease.

or you could buy a small super wrench this is a great tool stick it in google think you can get a set for 30 quid once yiu have them out replace them and as stated before grease the hell out of them! these wrenches come in different sizes and are very usefulfor other jobs too! best tool i have bought well worth it! dan

Can anyone suggest the best way to repair what's left (big holes!) once you get the old scrivets out?

 

I've got a nice shiny set of bolts (http://www.ebay.co.u...=item1e76dcec96) ready to go in but can't work out how best to build up the necessary support to install the new captive nuts. Has anyone successfully done this using a glass fibre repair kit? Any tips?

 

Cheers

I used M5 wellnuts smothered with copious amounts of coppaslip. Works very well in the enlarged holes left after you remove the rust and crumbling fiberglass from the original fixings. Full kits are available from Speedy Fasteners on eBay or if you already have stainless bolts just buy the nuts separately. Cheers,Jon.

Sorry just noticed you've already bought them. Why do you want to build up the holes? They are designed to expand when you tighten the bolts.

Thanks chaps 

 

I wasn't aware that the wellnuts expanded when you tighten the bolts up

 

For want of sounding more stupid do you glue them to the wheel liner? I almost lost one in a hole last night. Fnarr fnarr. 

[Mushter]

If you assemble them first it makes life easier and you won't lose the wellnut inside the sill. So, Bolt, washer, arch liner then wellnut tighten up finger tight then stick it into the hole and pinch up but not too tight until it won't pull out. Do coppaslip them though won't you. Dissimilar metals and all that.

[TheStotts]

Makes perfect sense. Thank you
