88..... I want more!

<< < (2/2)

ukmudmaster:
A hotter engine will run better, and burn more of the gum and other nasty stuff out of the oil. 92/95 is fine as a pressurised engine will not boil until way over normal boiling point.

Jonny Boaterboy:
Well I found one! After asking around I final found a local car parts shop with a guy in there who actually took a bit of pride in what he did. He got out all his diffrent suplyers catalogs and started going through them. He eventualy found one by finding the replacement termostate for the range rover which opened at 88 and then finding one with the same measurments that opened at 92.

It was the same apart from it did not have the little valve that you place at the top when fitting a genuine replacement thermostate (to prevent air locks I think) instead it had a small hole.

Now the big question...... did it make any differance....... well...... the temp gauge still sits in the same posision, but the heater does seem to be hotter. I know 4 degrees does not seem to be very much but try this little test for yourselv's but a thermometre under water running at 58 degees then increase it to 62... at 58 you can just about get your hand under it at 62 its too hot! I allso tested the termostate befor fitting it and found it was more like 96 when it started to open giving quite a bit more heat. My final test was carried out while we have had this cold weather. after driveing for about 30 mins the hot air coming out of the dash vents (soft dash Range Rover) got too hot to hold your hand over! Perfect!

If any one want one of these thermostates let me know and ill find the code and make for you

Merry christmas

Range Rover Blues:
Well I'd like to know for one, so if you don't mind....


Just be careful about that little peice of metal, in some engines they are more important than you'd realise.

ben_haynes:
just a quick note for you al VW fit a "Duel Opening" one looks similar size to ones i have fitted to my landys

if you dont understand "Duel Opening" it means the T'stat opens at 88 a small way to allow a small amount of hot water in to the Rad this allowing the whole system to warm up quickly and then fully opening around 95

i was going to see about this but i dont need it in the rangie as it gets hot enough for me

Bowie:
When I got one for my Rangie, they offered an 82 or an 88.... I went 88 of course, can't think you you would want to run at 82....... although I know a lot of racing engines run with very cool thermostats as cooler = less intake charge warming = more power as the air is denser.......

Not that that matters with a thumping great V8 in the front ;)
