i recently bought the above . it has been sitting garaged for a few years in need of a tank.
i got a tank fitted and drove it . the car started to over hea, i took it to mechanic who reckons cylinder head away, but could not work out the cooling system on the car as all he good notice was with regard to cooling the air intake!!
is there not a fan on these cars to cool as he could not see one and did not reckon the airintake would be enough to cool!!
any help would be great.

Not quite sure what you are saying here, not wishing to be rude but is English your first language?
As I understand it M's were fitted either with a tall radiator or a short one. If your spare wheel is stored under the bonnet with the radiator underneath it you have the short one. In either case your car should be fitted with a Kenlow-type cooling fan fitted close the radiator, by now in the car's life it may be either in front of the radiator (blowing) or behind (sucking). As the short one is so short and wide they are often fitted with two fans side by side.
I suggest you search the previous threads on this site as I'm sure this subject has been covered before.
Keeping old TVR's cool has always been a bit of a struggle, if your's has been standing a while I suggest you flush the system through (perhaps your garage man has already done that). It may be that the radiator is silted up to the point where it needs replacing.

excuse my english!!! i am in fact native !!lol
the mechanic could not find any fans on the car at all , perhaps they for some reason unknown to me have been removed in the previous history of the car!!
the car is overheating just ticking over!!
he seems to think though that the cylinder head is away which is going to be lots of £££££££££££

IF this is running a non pressured over flow tank you will need to upgrade the system to the later version (a modification to the radiator and the tower of water) also do check that it has a cast impeller within the water pump, with correct flow around the number 4 bore also ensure that the t pieces engine side of the heater valve has a re-stricter to ensure that you have good flow through the heater core.

Wow Adrian, give the guy a chance!! (crawl, walk, run - you're sprinting!) I agree with everything you say but I would suggest that Colin and Jasper have some good points!
Personally, if it's been sat a long time I'd start by flushing the system through and try running it without a thermostat to see if that makes any difference and go from there.

IMHO....This already with someone who cannot see a fan, IF it is where it should be in front of the crossflow radiator (upright radiators do not come into place until '79 AND NOT EVER on a 3000M, I will stand corrected but I have never seen one)..Historically the '73 car is a pain re cooling. The first 20ish cars come with a unique bonnet that the factory quickly offer a wide mouth moulding (to be cut and grafted onto the lower half of the bonnet) this gave better air flow through the car (along with a under the wheel deflector, seldom seen) but the route cause of over heating is the inability to get air out of the system.. In '74 they replace the vent on the drivers side of the radiator to add a pipe leading another vent to the top of the tower and then add an expansion tank into the system (blank cap on the tower and pressure cap on the expansion tank), However, IF the the re-stricter is not in place on the link between the 2 t-pieces then the flow through the heater matrix will not be enough to vent the high side of this of air by flow alone and any work done is worthless, and the heater will not work (due the easy route back to engine).
