They were fitted to TF's from late 2003 onwards. They are retrofittable, either by using OEM parts or there are several aftermarket kits availalble.
Rob Bell comes to the recue as ever, see here.

 

Did some looking into this and the options seem to be:

You could buy the £150 kit from Full Throttle racing, when I talked to them about fitting they admitted that it was a right pain in the wotsit even on a lift.

You could buy the bitts from Xpart, most are available although some may have to come from a scraped car or get all the parts from the latter.

Fit the PRT up front closer to the radiator like “MGTF Nut” has done

Don’t use PRT but go for a remote thermostat (such as the one from QED) housing instead.

Can anyone tell me how to check if mine has this? It was registerd in April 04 but could've been sat for a while!

Also, were there any other mods / HGF 'cures' that were fitted around this time??

 

I have borrowed this picture from GazSuttonUK (hope you don’t mind Gaz)

The arrowed bit is the PRT.

 

Cool, thanks Chris!

It doesn't look too easy to spot so i'll have a look on monday when the engine comes out.

I'm still panicking like mad about it :errx2:

 

You mean like this under the washer bottle?

 

Did you need to make custom pipes for that?

And Chris what is the difference between the PRT and the remote thermostat? You seem to contradict yourself :tic:

PRT is not only remote but also is different to normal thermostats as it will open with pressure as-well-as temperature.

The QED remote thermostat contains the normal thermostat.

 

But wouldnt that make the PRT better? :errx2:

 

Hmmm, just had a look at the QED housing.... Im assuming this is it

Looks nice, but a bit pricey considering I'd need probably need to factor in new piping, especially if I planned to move it to the front

Can't see the point of moving it to the front! If it's installed in the outlet hose before the bend to underfloor metal pipes it works damn fine.

 

Thats the one

 

The thermostat in PRT does not react to pressure but because bigger pipes are used for the installation of the PRT, this reduces the pressure in the bypass circuit meaning that the pump can flow more coolant. More pressure reducing than pressure reacting!

 

Yes, you just need to cut out a section of rubber hose to accommodate the QED RT and plumb in the bypass.

Damn.... now Im tempted to buy one! Im supposed to be saving for my Wedding in October! :yikes:

 

Mr Nut - I was replying to SP post about moving the QED RT to the front not commenting on your solution sir. The PRT thermostat does not react to pressure - it's a double wax thermostat - have a read here

Hi Chris, sorry

Yes, I read all that last year, and loads more articles before deciding on my course of action. Can't see how it's a double wax thermostat, there is only one wax bulb, and the article does say the operating valve flap is kept shut by spring pressure to allow for differential pressure across the pump. You can push it up and down with your finger against the coil spring!!
I think my little article may be in FTF No:7 coming out soon.
The top and bottom is that there is a larger thermal mass on warm-up, hopefully reducing, even more than the "official" PRT MG-R set up, thermal shock due to the rapid warm up of the original system.
Or something like that, only time will tell!!!

 

OK, from reading this lot it looks like Im left with two choices:

1. PRT thermostat (moved to the front preferably)

2. QED Remote thermostat

Im looking for something relative easy to fit and not too hungry on the cash reserves. Is there any particular reason to choose one over the other?

Basically no. You have to understand the arguments and reasons, figure it out yourself, and decide what to do.

No one here has the answer. If MG-R could/would not work it out, I doubt a few amateur mechanics can. It's all down to risk management. Do you leave well alone, make some sort of informed improvement etc?

Not what you want to hear, but there is no definitive answer, otherwise we would all be doing it

PS, I've got a lovely original MG-R fitted tool box now :stir:

It's the Stepspeed version so I am not sure what the difference is.

no difference according to Dieters EPC

 

Looks like they have more then one.

 

Wait a mo... B+G are referring to it as a remote thermostat... arent the MGR ones a PRT?

 

They are PRT and that is what is pictured.

 

So its just B+G being plonkers then

Its on my watch list, just got to clear the funds with the "Financial Controller"

 

I'm sure you folks have already seen this:

Nice fabrciation of a bypass using Porsche 944 and 1.4 Megane parts. Not too many of those parts floating about!

On first impression the graphs look good.

The guys should do more trials at higher ambient temperatures, plus they have probed the thermocouple in between the RAD fins, this would mean that the probe was measuring air temperature and not just temp of coolant within. If the ambient air temp was 3oC, thats just above freezing, it would be interesting to see if the temperature between inlet and outlet of the cylinder lessened as air temperature increased??

 

Could somebody what knows please confirm if the B&G kit linked above for the Stepspeed would be all that's required to add the PRT kit to a 2001 MGF. If it is then it's a bargain!

From what I can tell, yes. Although I am not sure if the plumbing is slightly different for the 160 due to oil cooler?

 

One thing to remember is that the Freelander has a PFT but still gets HGF.

 

The K-Series had NO business being in a car that size. :cus:

You essentially have an engine that began as 1.1, designed to go to a 1.4, pushed to a 1.8, in a car that needed a 2.0 that was capable of being thrashed....

Should never have happened No wonder the K-Series has a bad rep...

 

True but it could be argued K-series engine should have never been fitted to the Freelander. What ever you do to it, it still is the wrong engine.

I would beg to differ chaps.....

The 1.8 in the FL has more power than the Td4 or 2.0l series diesel. The doosels are better engine for heavy towing as they have better torque.

I just fitted a heavy duty clutch to the 1.8 engine, you'd be surprised at how capable it is, and still revs like a champion on and off road.

I fixed hgf last year from the OE gasket, fitted a new MLS gasket without oil rail, and kept the thermostat standard with a drilled stat ring.

10,000 miles later and still going better than it ever did

 

Unfortunatley a while ago David had his F written off by a young lad who span his car on a dual carriageway smashing it off the barrier late at night and than left it in the middle of the road, lights out, to sit on the verge. David swerved to avoid it having been alerted by running over his bumper and was hit from behind by another car while he was sandwiched between the barrier and the car. Having put so much work into his F he didn't have the heart to start again and was looking at other cars.
