i have coolant leaking on my passanger side foot area. where would this be comming from? thanks

This is coming from your heater core. Which when you look under the dash at your passanger foot area you will be able to spot pretty easily. Coolant has to pass through the core so you can actually get some heat inside.. On the downside when it gets old and wants to leak you get coolant inside.

it's only coolant, just shampoo the carpet real good

Yeah, but only if you're in the state of california.

Anyhow, it might be one of the hoses leading to the core, not the core itself.

heater core definitly

How expensive is it to replace the heater core? Get one from a junkyard! It really doesn't even need to be specifically for the Rx7, it just needs to fit right?

then again... who really needs heat in the first place? I prefer a hoodie.

One day I was driving and one of my heater hoses busted, so I got some new ones, and then start it up, and then coolant and water rush out from behind the dash on the drivers side. I must have muscled those hoses a little much and busted the core.

OK, I might try this tomorrow, but haynes doesn't say that you have to remove the dash... This is what it reads,

Remove the instrument panel, center console as well as the blower unit on the passenger side.
Remove the heater controls. Label and detatch the air ducts, wiring, and hoses and controls still attached to the heater unit. Uncrew the nuts and remove the heater unit...

Easier said than done. It looks like it may only the water valve where it comes in on the drivers side, I'm going to look tomorrow and see if I can get at it that way. If I can I'll make a write up of how it was done. Any one ever replaced one of these?? I've been bypassing for some time now, and don't like the cold drives or the hose that I cheaply bypassed it with. Was a poor collage student.
