Hey hello, this is my first post, my names Matt, i have this problem of when my car when she gets hot (normal runnin temp) and i turn it off, it doesn't start till the engine cools, i tried water on the 'CAS' but nothing, when i was under the bonnet the other day i found this little thing on the side of the motor behind the battery that was slowly leaking coolant, i wiggled the little leaver on the thing and it fired up first go, anybody know what it is and how much it is? i think its the problem but any suggestions would be nice thanks!

Hmmmmm.......that sounds like the heater tap but i cant see how that could effect the car starting at all. Not sure. Are there any other problems that you can find?? Have you checked the fault codes at all??
Let us know how you go and welcome to the club. I am sure others will give you some more ideas. Good luck!

What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

Does it crank- like try to start?
I know that starter motors can develop a problem when the contacts expand and it will sit there doing nothing until it cools. |

| it sounds like hes describing the heater tap but that wouldnt cause the problem, and the starters on the other side of the block so maybe by behind he meant throttle body? if so then maybe tps sensor, some one on streetcommodores had a similar issue and it turned out to be that sensor, but first impression leads to the cas as the water may not be cooling the unit down enough internally. |
Cheers,
Nodg. |

| it cranks over ok, i will try a new battery cos the 1 in it ain't too good, the throttle body has been cleaned out many times, the car is on LPG but it starts in petrol anyway, if it was the 'CAS' than it would cut in and out when running. i will keep trying other things and tell you guys how i went, thanks for ur help. open for any suggestions tho and i will try these things, Thanks! |

| Hey Matt, have you had a look at your relays or fuses? And can you hear the fuel pump going when you turn your key to ON? My only idea is that the fuel pump isn't working properly or a couple of relays have gone. |

| m8 try ya batt leads I had alot of trouble 1nc these suckers got going , it isnt the cas ! go over ya lpg sys and look for broken rubbers/seals ect! I'm takin you got a s1 being a 88 model , there are so many things that the s1 motor will go wrong with that s2 dont! you might have a fully jammed up cooling system , wich I will tell ya isnt uncommon ! I've sed this a few times b4 , but try flushing and if that aint workin have a shot a the thermo stat and another flush if that still dont work I will garantee the water jackets are bloked to the sh1t house, and thats a simple fix also, The s1 {if this is what you have } are fairly hard to kill trust me! Have a good look over ya head gassketts ! there are so many points we can hit here it aint funny , have ago at what the fellas suggested and let us know whats happening , it realy is a elimination proccess! |

| we did a flush about two days ago, came out as brown as the bottom of a petrol station toilet bowl, the bloke that owned it b4 me used water not coolant so, thats all done now i have coolant, thats how i noticed that thing leaking (some people suggested that its a heater tap), could be coincidental that it starts after i wiggle that thing around. what are the water jackets and how do i clean them? when i did the flush i also 'backwashed' it all out, to make sure i got all the s#!t out. it is a series 1. the thermostat opens at around the normal temp, and I'm pretty sure there no air locks thank you! BTW my LPG sys starts in petrol so could that still affect it? and if the cooling sys is jammed up would that stop it from starting when hot. Cheers! |

How often do you run it on petrol? And have you tried starting it only on petrol when its hot. The thing is the LPG converter uses hot coolant (water) to convert the LPG from liquid to gas. The converter has a diaphragm inside it that can shrink if the car overheats too much and not run properly.
I would check the following things (cheapest first):
-Coolant hoses for blockages especially those leading to the converter
-Coolant temp sensor(could be producing incorrect reading delaying the thermo fans
-The thermo fan itself
-Have the converter checked out by a LPG installer
Hope this helps |

| your water jackets , or the main 1ns that block up on the s1 engines are under the manifold/vally cover ( the thing your injectors sit on ) its fairlt simple but you need a steady hand when removing, I have always found the jackets clogged up with sluge and u can bet ya bottom dollar that if the previous owner was using just straight water they would be jammed right up , I do know as this happened to me a while ago if your car gets to hot it will die and wont start till cools down , the end result of jammed water jackets was I blew out a core plug at the bottom of the block , ( and thats a real prick of a job to put a new 1 in unless you prepared to pull the engine out ) |

I dont c the thermo fan being a real problem as I ran my vn right through summer with out1, also if you do remove the manifold cover get a new gasket for it! Try and get some fault codes m8 it would give you a fair idea were to start

| This problem plagued me. Ended up being the ignition control module. Initially i would do something under bonnet, jiggle something etc.. where-ever it stopped and I made ASSUMPTION that this had an affect. Pure association and coincidence in timing, no causality. Led me down a few paths I tell you! I had it in the mechanics a few times but they never discovered it, sometimes codes others not. I worked it out via reading, forums, reading manuals & logic. It shall be the last thing you want to try, but simple fast and EXTREMELY satisfying when car starts again when hot. try 2nd hand replacement. And if on LPG, no BACKFIRES from unburnt gas getting through intermittent cylinders. Good luck. |
