It's a terrible idea. :sad2:

[Smokey]

Thanks, i did remember there being a thread, how do i go about finding older threads.

Thanks Mat

Engines need to work at an optimum temperature, thermostats keep them there, you can run too cool.

never ran one......never had any problems

Are there any benefits for running without one Ian or do you just chose to not use one?

[rogerreno]

If you need to run without a thermostat surely all its doing is masking the problem of the engine not running at the correct temperature...

Providing the water pump and radiator are doing their job there should be no need to run without one, besides all you end up with is a luke warm heater!!!

I always ran a standard stat and fan switch in my Ph1 and never had any issues...and I was warm in winter :p

I took mine out today and tested it in boiling water. It didn't open up so I won't be putting that back in till I get a new one.

put it in a pan on the cooker and boil the water right up and it will open ;)

Yep tried that, it didnt open! :scratch:

under a tenner deliverd on ebay.

fit the stat . think of it this way if you put cold water on hot metal it shocks the metal
the stat controls the amount of temp the engine gets. having a stat in place slows down the cold water from the rad and you get less temp fluctuations . plus also with a stat in place your engine will be at its optimum temp and work better:)

[Sparkie]

don't forget that the oil temp is controlled by the water temp too. - too colder water will mean the oil temp is outside its effective working range.

yeah defo got 1 and it opens to. will send it out to you hulk :)

at what temp does the themostat open, as my engine since changing the rad is running hot iv bleed the system more than once but its still higher than normal.

Im going to take it out and do the test to see if i need a new one.

Thanks Mat

is it standard stats or are you running low temp stuff?

[Smokey]

mmmm well it was already in there to start with so i wouldnt know, is it best to run a low temp one or original fine.

[Alex]

The opening point should be stamped on the stat. When you say it's running hot, how hot? Anywhere between the 2nd and 3rd line is where it should be (I'm counting the first line as being the one at 9 o'clock) Standard is all you need..... :)

[Smokey]

like getting up to the three quarters then im having to turn the car off, i bleed the system again today and with the header tank cap off you can clearly see water returning, im gona take the stat out tommorrow to see if it fixes the problem and if it does ill get a new one.

[Smokey]

well i tested the thermostat yesterday and that works fine, so im going to take the rad out again tonight to give it a good flush out as it was lying around for a while so mite av some crap in it.

[Alex]

So the needle is heading into the 4 line/shaded area? If so that's too hot. Possibly a blocked radiator as you say......

[J8TRO]

Matt, Your rad was only fitted 4 months ago and was brand new..... be surprised if it was a blocked.....any other symptoms or just hot?

[Smokey]

not to the shaded area but to the second notch which is three quarters.

James the rad is fooked definatley leaking, took it out and got a replacement of ian with a different fan set up to the spal one. Im going to take the other one back. The rad ian gave me was lying around an i didnt flush it before i put it on. I took it off earlier and flushed it gona put it back on tommorrow and see if its worked.
If not ill take mine back and get a replacement one but if i can sort this one i can get some money back.

Im practically a pro at taking rads aoutt now thanks to you for doing it the first time.:agree:

[J8TRO]

didn't realise you'd had so many problems? i remember you having a leak but thought it was just the top hose connection that needed tightening.

I'd of been back down the place you bought it from the following day if it leaked!

[Smokey]

well it only recently started leaking its due to the spal fixings that go through the rad that have damaged it you cant see nothing visually but it was definatley leaking from where the pin went through the rad. Im going to take it back as soon as iv got this one sorted hopefully take it back by saturday.

I've been wondering this too?? can anyone clarify??

I'm assuming there is no need for low temp if your cooling system is working fine,and standard set-up and perhaps a low temp is used for cars with more 'tuned' engines running more boost etc etc..............

[IANMM]

std is ok but these little babies do run very warm so in my eyes the cooler you can keep things the better so Low Temp ones are a good idea but there not vital...

just a matter of your opinion really...

[Wallace]

Cheers Ian:agree:

Liked the feature on your car too mate - looks in great condition:cool:............

Feature what features this.
