Hi guys,

I noticed today that where the passengers feet go, it is leaking water(or something).

Im assuming that the big white box under there is the air con?

I had a look under their and its coming from the white box (air con? again not sure).

Can anyone help me resolve this problem?

Thanks

Stel

Yes it's the aircon unit (evaporator) and the water is probably due to a blocked drain hose. Condensation from the evaporator drops to the bottom of the box and drained to the outside of the car through a rubber hose that passes through the firewall into the engine bay. The hose will be attached somewhere near the bottom of the box. You need to check it isn't blocked in the engine bay (look for a black hose coming fom the firewall on the passenger probably with a right angle bend toward the road), or by crap that gathers in the bottom of the box after many years of use.

Thanks for the info mate.

I will have a look tomorrow.

There is another possibility....heater core. In that case tho the leaking fluid will be either green if your using coolant (although some coolants are red) or rust coloured water if your not (and that would probably explain the leak). Let's hope it's not the heater core.

yeah could well be heater core so check for loss of coolant....and if it is get ready for a big labour bill from the mechanic or a frustrating weeekend if you do it yourself.

All for a couple of cm of rubber pipe.....

oh man. heater core replacement is generally about 10 hours labour if you are using a good, quick mechanic. if they are slow, it will be more.

when the heater core exploded on our daihatsu we just looped the hoses and bypassed it. not recomended though as the heater can be useful for demisting the screen. either way you need to get it seen to asap.

My heater core went a little while ago... haven't gotten around to replacing it yet - just looped the coolant lines until I can be f**ked ripping the dash out...

yep...

by passed it today...

I just couldn't be bothered mucking around with taking the dash out.

I got quoted from 2 mechanic's, one 700 (performance mechanic) and another mechanic (who im selling his business for him) 1300.

FU*K THAT! lol

I think i would rather freeze in winter....

Thanks for the help guys :blink:

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
