Okay, really can't get my head around this.

You might know, but I've been having erratic overheating difficulties (go from cold to redline and back to cold in 3 seconds). Also, I've lately had starting difficulties. Both seemed to be seperate faults, but on a trip out I got caught out by both.

I thought I had solved these problems, I had replaced expansion cap, battery, starter motor and verfified alternator with a multimeter. She ran fine for a few days.

Anyway, out of the blue up the M6 the management light came on, i've been having tu1 conenction problems for a while so didnt think much of it, but half an hour later temperature shot to red line. I couldn't get it down. So I pulled over, stopped and let her cool. After a while decided to start her up again. It was then I realised that almost all the electrics were....toast. The battery had no charge, and our battery booster made no impact. The starter motor solenoid would not even give me a click. The cd player was dead, everything was just gone, except the dash lights which seemed strong. Hazards worked but were dim, even with battery booster (fully charged) connected. battery was in good condition before I left because it has an LED on it I checked before the journey as I examined my tu1 wiring.

Because of my dim hazards, a police car pulled over and put me through everything, insurance checks etc. I came up fine and they lent me some cones until a recovery guy came out to me. Which was nice of them i guess.

Anyway, recovery guy had one of these huge booster packs, and we couldn't get a bloody thing out of my car. Not even a solenoid click. He mentioned the immobiliser, we checked the fuses, starter connectors and earthing points and gave all a clean bill of health.

Anyway, had to recovered back home, all 100 miles. Dropped her off at my unit, and as she rolled off the truck I put her in gear, lifted clutch and she bumped into life. Promptly overheated, was shut down again, and has been unable to start since.

Only consolation is that the engine isn't seized, but headgasket certainly wants checking, and the smell of heat was overhwelming.

Where do I even begin with this one, lads?

change that to Ti and I'l send negotiators with coffee.

I'm just a bit fed up, wgt on saturday and i've a dead car. I'm going to change thermostat if I can find the time, but I don't really trust my car to go with all these starting issues, so I think i'l have to give the run away, even if I solved the overheating.

If the problem turns out to be immobiliser related and expensive, I think I'l just buy a t series if I can or get a 2.2 16 valve frontera and just whack boost up on that because its a torquey beast and despite its weight its lovely city driver as its got so much low down power.

might help haha. I do need to know whats fecked with it.

Somethings wrong with the power, despite the big three - alternator, battery and starter have all been replaced (except alternator which has been confirmed with multimeter).

And somethings wrong with the coolant system.

If changing thermostat doesn't help, then it means im going to have to inspect the water pump. Whilst I have a spare brand new aux belt, I don't really have the time before saturday to spend a day with a haynes getting everything done, so I am getting myself prepared to say goodbye to rovers for a while. Sadly.

Sounds like your having a bit of electrical fault esp as the battery is in good nick. I had a problem once with the live wire that hooks up to the battery. This gave me very strange electrical problems even when driving. My temp gauge also rose high then dived down during this ordeal. New wire and it was grand.

Also as I think I said to you before I had overheating issues with my ZS. Would be warm one minute, then working its way to hot and then back to cold again. I changed the thermostat and it never done it since.

theres a local rover specialist just up the road from my unit, so they've got it at the moment. They are unsure of the fault, but have confirmed the suspicions i posted about a few weeks ago with the cooling fans because both are dead. They sya they haven't yet been able to verify if it could cause the overheating on a motorway or power drainage.

thats why they wern't going to say they'd found the problem. It's definitely overheating because you can smell it.

In that case it's probably the water pump impellor, thermostat (they did say one rad pipe was cold and one hot) or an airlock. They managed to get it started by charging the battery overnight. And they've tested the battery and alternator and both are fine, though the battery obviously suffered severe discharge as I couldn't even get it jump started with a wagon battery as an aid! (just the one though! - 12v).

So we're still bemused. Love to take you up on the offer dan, but unless you work odd hours it probably wouldn't work as i've commited myself to working for dad through tomorrow and i've two computers to repair on the evenings (one today another tomorrow, il be setting off in an hour). Really would have been handy though! Looks like i'l be working into the AM's to try and get my head round this if the 'trician can't.
