So, basically, you are still out of pocket for 1 thermostat, surely whoever supplied that thermostat should reimburse you for that?
what thermostat???

- Start date
well that's the bottom line Robert, I got one back so will keep chasing the other until it is resolved, some amount of time and e_mails though lol, im surprised they haven't given in yet coz I certainly wont 
I'm running without one...
The stat sets the floor not the ceiling and does not control the viscous fan..
Other than more engine wear on start up I see no disadvantage ..I will compensate by running 10w60 oil which is specified as ok in the the M44 handbook and the higher viscosity will protect the engine at lower temp..its the lesser of two evils. .if the M44 overheats you will be changing the head gasket and getting a warped head skimmed.
trust me.
Have done 2 now!

i still havent changed it Joey, running 2 months like this now and feel way more comfortable about things, however, i will change it when i get a chance as it will do damage to my cat and to my engine internals from the engine sweating, it is not advisable to run without one for too long my friend
On start up with 10w- whatever you are starting with 10 weight oil which thickens up as the oil heats up. You should be running a 5w to provide lube when oil is cold. Here where the temps drops to -40 or lower 0w is recommended. I agree with David, running a stat saves other engine/ exhaust parts. JIM
obviously the stat is there for a reason...but blimey, if they fail closed its a big issue,
having just been through hell with this engine I am doing whatever creates a free flow of coolant..yes she will run rich for longer on start up but the engine will still reach temp and then its all as normal.
I may just fit a new stat in the next day or two ..althought this one as new a few months ago it seems to take a long time to open on start up.
re the oil, I stand corrected that is 100% right.
i'm just about to drop the oil and do a service after the head replecement, I just have some final timing to do before I do it..will stick to 5w40..
its cheaper anyway!
i'm just understandably cautious now with this engine and cooling.....95 degrees seems very hot for the thermostat to open.

I just took a screen capture and posted that for effect as the explosion was due to a LPG cylinder explosion - I wanted to avoid the actual reason!
I reckon that there must be (always) a leak involved.I wanted to avoid the actual reason!
Nice touch, the Lexus hoods open up from the back! 
so this evening i put in the new gates thermostat, all went well... talk about nerve wrecking though, think i watched the stat more than the road on the way home, going to be a few nervous days ahead .....
David , I can relate..
have one eye glued the the temp gauge these days....!
I went ahead and fitted the stat, I was running without one and I must say the car gets up to temp much quicker...we did an oil change at the same time with 5w30
I can report that if you leave the front end up on jacks whilst bleeding the system the airlocks all go to the highest point....I have never refilled and bled a system of coolant quicker on an M44 than when doing this.
a nice little incline or hill would work just as well...
happy to report she is running fantastically well..!
just as well as some t**t drove into the side of my alfa on the M4 she is in the body shop..not happy
.if not for some very tasty driving on my part i'd be writng this from heaven..or at very least a hospital bed.
some people!.
anyway nice to have the zed back and runnig like a champ!

Nice to conclude a thread, well done Dave, happy motoring.....
thank you Zed, delighted to have all back on par again thanks
thanks
Niceone this infomation made a full service and thermostat change a very quick job over the weekend. Nice little engine to work on too. Lifting the nose in the air made bleeding the system only take minutes.
