Intercooler Cowling

[rambler]

hi folks / anchorman

lifted the bonnett on my rav during lunch today,and noticed that the rubber / plastic cowling attached to the underside of my bonnett is very loose on its fixing clips.

i can stick my fingers through the gaps in the bonnett scoop and 'wiggle it' very easily indeed.

question then......can i run a bead of clear silicone around between the underside of the bonnett and the plastic cowling to stop it rattling / vibrating?.

as i cant see a way of tightening up the plastic fixings !

would normal bathroom silicone be ok,i believe its heat proof.....ish

obviously the rubber sleeve will still 'drop' onto the surround of the intercooler as normal

could this...really so simple cowling be what i can hear rattling from in the cab

Yes you can use bath sealant for that and yes it could be that and I hope it is but I have to say I doubt that it is.

hello

as per my practice -- the badroom (normal) silcone suffers from high themperatures, especially in engine compartment + especially in summer time.

youo should use high temp resist sealant that is normally sold on the market and it does job even up to 200-300 C degrees.

DO not try with bathroom silicon otherwise you will be forced to remove it after a while. Cheers/Igor

Its OK to try it Igor then he can find something better if it works. There is nothing to lose.

hi folks

right...have pumped 'quite a bit' of clear silicone into the void between plastic cowl and underside of bonnett,it was tricky as could'nt remove the sound proof matting too easily.

ive been in plumbing / heating for almost 20 years now

but being an ex plumber !, i'd forgotten how mucky and sticky silicone really is,but with a bit of tissue and the occasional smear with a wet finger i reckon ive done a half decent job. ;)

and after a couple of hrs its started to 'go off' and developed a 'skin',and i cant 'wiggle it' anymore...only trouble is,front of rav currently stinks of silicone

and to top it all off...last night,i discovered water dripping through our ceiling from the loft.. :o ,our house (i live with my mother ) has 50 yr old copper tubing,which was imported in 1960-70's,this is known to 'perforate' as poor quality..and yes ,very small limescale deposite can be seen on the surface of it.

so this weekend ..new storage tank,and pipework renewal ,all in a loft with.....steel joists at 2'6" centers

rrrrrrrrrr......i hate plumbing,especially at home :censor: :censor:

and i cant charge mum a thing for it ;)

yes - nothing to lose but the problem is that is't hardly to remove a harden silicon and it is a risk to scratch a painworks, if any.

but for sure each trial gives an experiemce. Cheers/Igor
