Hi im wanting to fit a kill switch to my car some one told me to do it directy from the fuel pump any ideas

Rogviler

Yeah, probably running one of the leads for the fuel pump through the switch would be the easiest way. If you have an extra spot on the instrument cluster switches, that would be a good place to make it stealthy.

Where is the heater core and how will I know if its at fault thanks

You might want to invest in a repair manual. The Bentley manual is the most comprehensive but it's a little pricey. However, if you plan on doing a lot of work yourself, it's money well spent. Even the Haynes manual can be a great help. They are cheaper but not as comprehensive. I actually have and use both. For bigger, more intensive jobs, I go the Bentley manual. But for simpler things, I go to the Haynes.

You can often find them cheaper, or even used to save some money.

Yeah, definitely get a manual. It'll quickly pay for itself in the time you save.

I would run the car up to temp, make sure the heater valve is open, and then see if both the hoses running through the firewall are hot (or warm). If they are then the heater core is probably not the problem. If you're getting no heat though it's going to be a blocked core or the valve is faulty.

The heater core is right behind where the hoses go through the firewall, sort of behind the glove box. Once you start taking panels off you'll see it.

The pipe is warm so what else could it be

Rogviler

Both are warm? It could be a partially clogged heater core in that case. It's really not hard to replace, nor expensive, so I wouldn't hesitate to just replace it. There isn't much it could be if the valve works and coolant is definitely getting to the core. I mean, I assume the blower is blowing and obvious stuff like that...
