Next weekend I plan on doing the following jobs and would appreciate any help/advice that anyone could offer.

1) Replacement of temp sensor behind front number plate.
2) Replacement of both heater to engine block hoses.
3) Replacement of under bonnet/hood insulation pad.
4) Replacement of all belts.
5) Change front spring pads to 1 bump items.

On number 3 there, I would not try to do any short cuts on this one. You will just wind up with a pad that falls off again, trust me on this one

Performance Products sells a couple of 3M products for this. One is a glue remover and the other is a trim adhesive. You can get these products at any automotive paint supply store.

Thanks for your reply - is there any special type of glue to get or avoid? Anything that will eat into the pad?

Cheers
Matt.

Just make sure you get professional grade trim adhesive and you will be ok. Clean all the old glue off first.

Thanks Q, what's the best way to remove the old glue?

Thanks Q, what I meant was do I need a scraper? Do I pull all the old pad off first etc?

First, degrease the underside of the hood with whatever is the equivalent of our "Gunk" engine cleaner, followed by a good water rinse. Might as well clean your engine compartment at the same time as it is going to be a bit messy. Let dry, then either wipe all underhood surfaces with clean gasoline or whatever solvent that 3M or equivalent is selling. Be careful! Once it is clean of any oil or residue, put your new pad up in place and put some alignment tags on it and the hood with masking tape. This is so you can place the pad in place accurately - you only get one shot at it once the glue is on both surfaces! (You start at the center, then do the sides.) Next, mask offf your engine and fenders and windscreen, then apply the spray glue to the hood and the pad, let them dry for the right amount of time and carefully apply. It worked for me!

Research the information on the temperature sensor on this site. Good stuff written. Sensor is less than $2.00 if you buy it right.

Thanks very much for a helpful response Ron.

Cheers
Matt.
