Isn't it disappointing when you discover the "nice guy" you bought your car from might not have been quite as nice as you though?

After the overheating issues (Otter switch failing) and the fact that she runs about 5 degree hotter than I'd like (and the fan comes on even at motorway speeds) I decided to change the thermostat..

Taking the housing off, there is no thermostat!

So much for the idea that it might just be a partially sticking thermostat causing the slightly higher temperature.

Well, I'll fit the new thermostat and hope that the previous owner mis-diagnosed the failing Otter switch as a failing thermostat and that's why it's been removed.

Such a shame, I genuinely thought he was a nice guy. I suppose it's possible that he took it to an unscrupulous garage and they did it without his knowledge but then the best I can hope for is that he was a sucker.

Hopefully putting the thermostat won't make things worse. Can't believe how rust coloured the coolant is considering the radiator is nearly new so I can only assume the system wasn't flushed properly either.

Oh well, it could be worse!

Disappointing I'd agree but I wouldn't assume that makes them a bad guy. We've all bodged things to keep things going and I know I've sometimes forgotten frown

Not everyone has the same level of mechanical competence either and many people think removing the thermostat is a fix for overheating...

Hopefully an easy fix.

Of course this is PH and so obviously you should pop around to the previous owner with some company director, goatee wearing, powerfully built friends wink

Bit harsh.

All sorts drive TVRs - some rely on garages to maintain their car as you point out yourself. A missing thermostat could easily be an oversight eitherway.

Harsh? Did you mean me?

I think I know almost every nut and bolt on any vehicle I've owned for a reasonable period of time, I know every little "bodge" I have ever done and would ALWAYS declare all of them to a potential buyer, that's just the right thing to do.

Personally I thought I was being reasonable just saying I was disappointed and that he MIGHT not be such a nice guy. OK maybe "sucker" was a bit harsh, maybe... But I don't think so.


Big mates with goatees - that I have in spades (and I am one of them myself) but I don't think he deserves to meet them, he seemed nice enough, guess I'm just disappointed he either didn't have enough knowledge about the vehicle he was selling or was less than honest, either of those is reasonable grounds for disappointment.

Yeah, just came across as a bit harsh, that's all. Easy to forget to mention a missing thermostat or not notice a garage hasn't replaced it if you're not familiar with spannering. Wouldn't it just be slower warming up if it was missing ?

If the coolant is rusty I would drain it and give it a good old flush before putting some fresh stuff in. You're going to have to drain it partially anyway so you might as well!

Yep, full reverse flush and replacement coolant. Probably steer clear of water wetter and probably dilute the antifreeze mix a bit now it's (apparently) summer.

Changing the rocker cover gaskets at the same time as they've dried out and leak a bit.

I keep forgetting this is a 24 year old car, so all the "old bodges" work (ish), maybe I was a bit harsh I suppose it is something that could be overlooked, it's possible that it was removed over 20 years ago LOL

HOLY CRUD!

OK, that adds some perspective... Missing thermostat or death-trap... I'll take the thermostat anytime!

Pretty frightening, huh ?

You'll also find several 'OEM' bodges. When I took out my dash I discovered the heater lights are given their colour with electrical tape . Some of the bodging in my loom makes me weep. Not dangerous but you understand why they get their reputation for unreliability !

Still love it, mind.

My car also had a new rad when I bought it but the water was thick brown sludge. It also ran a bit hot but did have a stat in it. Gave it a good dose of rad flush and plenty of washing out, then drove around with plain water for week before flushing out again and adding the antifreeze. Could not believe how much crap came out of it. Afterwards it ran way too cool till I modified the bypass. The stat (on the 2.9) also has a plate that closes off a hole in the back of the housing as it gets hot. Not sure what that does but if theres no stat it stays open, this might allow the water to short cut back to the engine.

Rust coloured coolant....running hot. Radweld thrown in by previous owner incase of any leaks/water loss?

Flush the system.

and finally ensure the swirl pot has the right cap on it and that it draws back from the header when cooling and never leaks

Would you mind elaborating on that. hehe

Alright for you, you're off on holiday - we're going to spend a week debating whether the blanking cap fits on the swirl pot or the overflow tank...

Don't forget to flush the heater rad while its in bits. Also beware it might look like you had an incontinent elephant on the drive when your have finished!
