Yes, that is is the new Pressure Relief Thermostat (PRT) that is meant to reduce the incidence of HGF on K-Series.

Its a picture of my TF buy in july 2003 ! and i have this modification no ?

i am amazing i think its 2004 modification ???


bugman23

The PRT was fitted to engines produced from Jan 2003 onwards. I suspect that it was a while before cars appeared on the streets with this fitted. However, you appear to be one of the lucky ones :-)
Dave Livingstone

Hi :) Its A TF modification ?? or a TF jan 2003 modification ??

bugman23

It's a Jan 2003 modification to the engine. TFs built with engines built before Jan 2003 will not have this modification.
Dave Livingstone

Bugman, what is the VIN of your TF? Would be useful to know to nail down the introduction point of the PRT thermostat upgrade :o)
Rob Bell

The engine 18K4KN27 507251 in my March 2002 TF 160 SAARDLBPC2D 602303 certainly does not have a PRT.

Rob,

I posted the exact VIN start for the PRT introduction and a later update in a thread for Dieter a few weeks ago. A look in th earchives should find it. As I am at work and can't log in due to fire walls, I can't look it up myself.

My vin number :

E11 * 93/81 * 0017

bugman23

# 2 = Model year 2002 started app July 2001
# 3 = Model year 2003 started app July 2002
# 4 = Model year 2004 started app July 2003

i think when they are 4 after KN they are the prt modification...
bugman23

Thanks bugman! :o)

David, I can't seem to find the thread in the archive - any recollection of what it was called? Cheers :o)
Rob Bell

And THE QUESTION :D are they MGTF with PRT who are do HGF

:D

bugman23

>>are they MGTF with PRT who are do HGF

For sure there are or will be, but many will be caused by the same issues as on the F - expansion cap failure, split hoses, underbody pipe corrosion, rad fan fuse blowing, rad bleed screw shearing - anything you can think of that will cause coolant loss that goes undetected and causes overheating!
Dave Livingstone

Recalling we talked about it, but I miss the VIN ??

Some of interest.

PEM101020 is the p/n so far.

Arggghh, the BBS software removed the first access code only ...
Dieter K.

Rob, Dieter
the title had Dieter's name in it I recall. I also posted on the mg-rover board so i will go over there where I have ab back door (thanks to Steve Childs) at work to look at the archives and see if I can find it.
David M

OK, this is a direct quote from what I said on the other forum
"The prt was fitted from chassis 629951 and was updated again from chassis number 638640, though he can't see what the difference is"
The 'he' in the above was the MGR dealer's MGF technician who was looking at the MGR supplied data.

Hope this is of some use.
David M

>Arggghh, the BBS software removed the first access code only ...

Doh, on a connected note have you had a look thru your referrer logs? they'd be full of peoples access codes (100+ accesses to my flexi pipe replacement guide)
Will Munns

"The prt was fitted from chassis 629951 and was updated again from chassis number 638640, though he can't see what the difference is"
on a similar note, the first PEM101020 I bought is black, while the second one (same item, but on a complete kit) is semi-transparent and with minor differences on the bypass valve.

The You. Secured on site now.
:D
David, I searched like mad with VIN number, FAO and other keys, but can't find the thread in the archives ??
Anyway.

Regards
Dieter

If "The prt was fitted from chassis 629951 .."

How come bugman's 620580 car has one?

John Thomas

Good question John. Leaves us still pondering rather doesn't it? Anyone else have a VIN number around this area that they can check? It is possible to see the thermostat from underneath the car as Bugman's picture shows.
Dave Livingstone

I think Dave Stonehouse will miss it, but Silvia W. will have :)
I'll drop her a line and ask her.
Dieter K.

The VIN number on my TF is 608321. It's a July 2002 TF 135.

I most probably don't have the valve, although I will check. I also recently noticed that I seem to have "mild" HGF.

No overheating but fan comes on at idle and I noticed low coolant level + white residue on the dipstick. No mayo in coolant expansion tank yet... but it's going to the dealers - slowly - for a check-up.

Thanks for the part number, I'll ask my dealer to change the valve too if it is HGF.

Merci aussi Bugman pour la photo.
