I wonder if anyone could please help.
I am not really technically aware on cars but will explain the best i can. Recently my head gasket went which t this day I am not sure fully why. I was in Scotalnd visiting friends at the time and got a local garage to do the repairs. I have had the head skimmed and pressure tested, and a new timing belt. I picked up the car at the weekend, and noticed that my temperature gauge was going up too high, which also resluted in no heat from my heater. I checked my over-flow tank and saw that the water was being blocked somewhere and forcing its was back out. I took the car back to the garage, who advised me that it was more than likely an air lock, which he 'corrected' I drove back down to Leeds where I live, only to gt 30 miles, for my thermostat to rise/drop again. Eventually I had to be towed all the way back to Leeds via Green Flag, who advised it may be another air lock as well as many other things.
I have asked a local garage to look at my car tomorrow to check for me, but I am just wondering if anyone has any suggestions what they feel the problem may be. I have spoken to the Scottish garage, who advised me he took all the pipes off to clean to try to prevent an air lock. He did advise me if this makes any difference, that my car does not have a thermostat.....And it mustn't have had one since I have had my car (12 months) could this be a cause, as i havent had any probs with over heating before.
It is a 96 N car.....
I hope i have kind of made sense.
Thanks

NO thermostat??? I've never heard of a car without a thermostat at all!
But if it wasn't a problem before, it probably shouldn't be a problem now. Did the scottish garage not think to put one in then, when they saw there wasn't one at all in the first place?!?
At least this'll take your thread back up to the top of the list again, might get noticed by the more experienced folks on here

When I mentioned to the garage about the thermostat. they thought I had had it taken out for a particular reason.....
Not the case...>I didn't even realise...
But like you say, it hadn't caused me any problems before.
Thanks for the reply though

Symptoms do sound like an airlock, I'm not familiar with this engine so I'd buy a Haynes manual and first of all ensure that you've bled the system per the manual.
The lack of a thermostat would suggest there was an underlying problem, there may be excessive corrosion in the had causing flow problems - is the heater matrix supplied from the head?
I'd check that the water pump is functioning, I'd probably flush the system and try to identify any flow issues.
Best of luck

You would know if there wasn`t a thermostat fitted as the engine while driving would never reach normal running temp.
untill you stop then you would see the guage move.it is possible and likely you have a seized stat or opens too late
I assume it is the rover unit not honda ie not auto box

Hi,
I think it's unlikely the stat is seized or opens too late - because the poster stated that there is no thermostat :-)
I think the whole thing sounds fishy - thermostat had been removed, and the cooling prolems remain despite having been bled twice. Something more sinister is the matter... no?
Cheers,
Mark

He was told that.but there was no mention of overcooling which without a stat would happen on a run.

This might be of interest: someone else has already posted it on here. Methods of removing air-locks: www.lame-delegation.de/mgf-net.de/hgf/hgfcauses.ht...l Must be a poor garage to let a missing thermostat go by!
