Hi guys

got a weird problem I have intermitent overheating sounds daft but could this be in anyway be related to a heater matrix leak?

define "intermittent" need more info bud, could be related if you do have a heater matrix leak as it would be drawing air into the system and also leaking coolant into the cabin.

ok sometimes the car will start and alarm will set and unset half an hour 2 hours 2 days later nothing and I have to jump the car to get it started no visible drop in coolant replaced thermostat and drained coolant flushed rad

thanx

not sure im following you, the alarm will set? do you have a temp alarm?

ok the car alarm wont set or unset the car it wont start no light on dash no headlights jump start the car everthing works ok then at anytime the car will fail to start as said this maybe 2 days 2 minutes 2 weeks completely unknown when it will happen

cheers

OK, i was replying to your overheating issue which from the thread title was what the thread was about lol

 

The alarm issue could be all sorts. but you would probably benefit from putting a different post up about that, as that just got very confusing going from over heating to immobilizer problem like that.

hi vod

the imobilizer problem is all linked to the main problem as its electrical problem !!but would jump starting the car have anything to do with re-engaging/ dearming the alarm if at all related to the the non starting I know its bloody confusing

lift carpet on passenger side of car and remove the wooden board, check ECU and surrounding wires for damp / wet. do you have a curry type smell in the cabin? as that is sometimes associated with a leaky matrix.

got water in footwell eliminated targa drain recon matrix then electric problems/overheating?

Could be the connectors now suffering from being wet due to the matrix, best check the ECU connectors, are you sure its over heating? might just be faulty signals due to the wiring needing a good dry out and clean.

no its overheating steam coming from engine lol and hoses hot

thanks mate

Steam, thats worrying, id be inclind to get that block tested for HG matey, they dont last long, mine over heated to 125 degrees twice and now i have smoke coming from my exhaust :(

checked targa for leak all ok dash out and heater matrix ok no leaks weird as fxxk the car started first time and three times after today

vod not to worried about the engine as its going to jimmer for rebuild and pistons soon :biggrin:

found electrical problem hazard warning switch stuck in draining battery omg found water leak reglued targa drain plug in wing but had split since i last looked at it

 

two down one to go overheating still to sort

going to take the rad out and all hoses

done burp test on lower rad hose loads of bubbles came out of rad valve is there another way of eliminating all air ?

omg rad fan not working will buzz it out

took fan out and put 12v on it all ok checked rad/brake light fuse ok and switched relays on main fain box from air to fan and vice virsa

checked voltage at fan plug and only got 4v help please

by passed ecu temp sensor shorted out the two connectors and fan came on helppppppppppppp

Give me a call on 07786310989

thanks mate will do bit been chasing my tail knowledge is power lol

big thanks to you steve and like I said if you ever need a hand give me a shout

let me know if it works bud i hope it does. you could do with hooking up conzult or datascan to see the actual ecu temp value rather than the dash mounted gauge.

hi just brought conzult from flee bay got it today will check it out and keep you posted

thanks mate
