A/C - water control valve	Application:                          TR7/8 Triumph Part #: AAP128 Other Part #’s:                     Volvo 1348252-6, Ready Aire # 5864, Everco # H6345. Old Air Products H16-5000 Other Vehicles:                    1973-1991 Volvo 140-164-240-260 References:                          WWWedge e-mail list, TR8CCA newsletter Comments: As of September 2014, the current opinion within the wedge owners community is that there is no readily available replacement valve.  The following information is presented in the hopes that someone can use it to track down a suitable replacement.  Ranco type H Heater Control Valves for 1973-1991 Volvo 140-164-240-260.  Original part number 1348252-6 superseded by part no. 9131998. The original part makes the wedges necessary right turn, but the replacement part does not. Voluparts in Atlanta used to carry a version that works. See also the TWOA newsletter: issue 16 (Pg 3) for an article by Ben Zwissler, on how to rebuild the valve using a NAPA Balkamp 6601000 parts kit. See also TR8CCA newsletter: issue 53 (pg 16) where Odd Hedberg mentions Old Air products part number H16-5000 9054 01 Made in UK. See TR8CCA newsletter:  issue 51 (pg 8) for instruction to repair the Thermostat switch using Old Air Products replacement parts per a letter from Bill Sweeting. See TR8CCA newsletter:  issue 58 (pg 27) for instructions by Peter Nussbickel, on how to replace AAP128 with a manual water shutoff valve.  The valve is actuated inside the car via the heater console leavers on the Dash board.   While the repair was originally designed for an A/C car, this is a great upgrade to heater only vehicles so you can shut of the hot water flow through the heater matrix on hot summer days.
Engine Coolant	Application:                          TR7/8 Triumph Part #:                   N/A Other Part #’s: Other Vehicles: References:                          TR8CCA newsletter Comments: See TR8CCA letter, issue 42 (pg 3) where Don Swetzig shares a letter from Texaco Lubricants on using DEX-COOL as an engine coolant on the Aluminium TR8 engine.
Heater Matrix – non-A/C	Application:                          TR7/8 Triumph Part #:                                   DZB3226 Other Part #’s:                     Robsport DZB3226 (pictured), Kuhler Schneider DZB3226, 4season 94651,  VW 171.819.031C Other Vehicles:                    1976-82 Austin Princess References:                          e-bay, Robsport, WWWedge e-mail list, TR7Forum.com Comments: “New heater matrix for all model Triumph TR7 and TR8 (non air conditioned models).  Remade with a pair of pipes coming out of matrix (see top picture at left)  so there is no need for the seals (which are obsolete anyway!), just trim the heater pipe and attach a length of rubber hose to each. New item.  Part number DZB3226.” – Rob Sport “I read (http://tr7triumph.com/forum/viewtopic.php?f=2&t=22482&hilit=jetta) that a VW Jetta matrix (VW 171.819.031C or 4season 95651) worked OK with a little bit of fiddling and they are quite cheap apparently. Not sure what those are called over in the USA” - Russ Cooper (Aug 2015) “Further research shows that the heater matrix suggested on TR7Foum (4season 95651, see bottom picture at  left)  is also listed for Audi 80/90/100 models from 1972 – 1978 and  VW Rabbits 1981-1983.   The pipes come out at a slight angle to one side, but apparently can be made to fit quite nicely.  The core itself is a modern construction, made of aluminium with plastic end tanks, which removes a significant amount of copper from the cooling system and if paired with an aluminium radiator should reduce corrosion due to dissimilar metals.”  -  Mark Elbers  Alternatively:  If you don’t trust the original rubber seal arrangement, you can remove these bushings altogether by soldering the pipes solidly into place. “I rebuilt my heater core a couple of years ago. I bought a used heater core, disassembled it, and took it to a radiator shop. I explained to the guy there that I couldn't get the matrix seals and that I wanted him to braise the pipes onto it instead.  He cleaned up the heater matrix inside and out.  I seem to recall that he used a couple of top-hat looking copper sleeves that slid over the pipes and fit flush against the matrix. He may have braised them over the two holes in the matrix first, and then inserted the pipes and braised them in place, and pressure tested it. The pipes then had to be cut in order to put the matrix into the heater core. After the matrix was installed, the two halves of the pipe were connected with two short sections of hose and four hose clamps. He had the other heater core parts there so that he could get everything lined up correctly and cut the pipes at the right place. He charged me $125 to do this. Well worth it to no longer have coolant dripping on my foot. That's the way that I would recommend rebuilding the heater core.”  -  Alan Woody  (August, 2015) “I soldered both of my tr8's. One with a/c the other without. Both have worked great for years now.” - John Sanders  (August, 2015)
Low Coolant Level Sensor – Grommet	Application:                          TR7/8 Triumph Part #:                   C43221 Other Part #’s:                    Victoria British #2-424 Other Vehicles: XJ6 79-87 XJS 76-96 References:                          WWWedge e-mail list Comments: This grommet seals the low coolant level sensor mounted in the header tank found on later model Wedges. For the XJ6 79-82 and XJS 5.3L this fits on the Radiator For the XJ6 82-87 and XJS 3.6L/4.0L this fits on the Expansion Tank “The part number is C43221.   I got it from Motorcars Ltd., apparently it is used in quite a few Jaguar models: http://www.motorcarsltd.com/C43221.html”   - Darrell Walker “The coolant temp sensor grommet, C43221, is apparently not available from Motorcars Ltd anymore.  Jagbits (http://www.jagbits.com/) carries it, as does Terry's Jaguar Parts (http://www.terrysjag.com/)  - David Elsberry (July 2013) TR8CCA newsletter, issue 83 (pg 3) listed the Jaguar part number as C432221.

For the XJ6 79-82 and XJS 5.3L this can be found on the Radiator For the XJ6 82-87 and XJS 3.6L/4.0L this can be found on the Expansion Tank
Low Coolant Level Sensor – Signal Transmitter Unit	Application:                          TR7/8 Triumph Part #:                                   RKC5259 Other Part #’s: RKC4149 (supersedes to RKC5259K) Other Vehicles: References:                          TWOA Technical Reference Bulletin library Comments: Technical Service Bulletin T80/024 describes how to test the unit and recommends upgrade to RKC5259 under warrantee if necessary. The Rover SD1 part number DRC8562 (pictured) has a similar looking housing, but with a different connector.  It might provide a suitable replacement once the connector is changed for the wedge one.
Radiator	Application:                          TR7/8 Triumph Part #:                                   RKC137 (1975-79),  PKC1359 (1979->) Other Part #’s: Other Vehicles: References:                          WWWedge e-mail list Comments: Wizard Cooling aluminium radiator model number 99014-100.  Performance radiator and a direct drop in for the TR8.

Radiator Fan Motors	Application:                          TR8 A/C Triumph Part #: RKC3107 Other Part #’s: Other Vehicles:                    Fiat 124, (possible Strada’s) References:                          WWWedge e-mail list Comments: More recently, Porsche Boxster fans (pictured) have been adapted with minor changes to the wiring.  The Porsche fans also use a more efficient fan blade design and the motors draw less electrical current.
Radiator Fan switch –Radiator and Engine mounted	Application:                          TR8 Triumph Part #: TKC5532 / TKC5050 Other Part #’s:                     Jaguar DAC3061, Volkswagon 823959481, Wells SW533, Standard TS-151. Other Vehicles: 1985- 1995 Saab 9000, 1977-87 Jaguar XJ6, 1980 VW Rabbit 1.5L. References:                          WWWedge e-mail list,  e-bay, TR8CCA newsletter Comments: The actual temperature on/off settings for these switches seems to be the subject of much discussion and many information sources contradict each other.  Use the following information with caution. TR8CCA newsletter, issue 25 (pg 13) Fred Smith suggests for the Radiator, replacing TKC5532 (threaded, closes @ 102 C) with TKC5021 (closes @ 97 C) from the Spitfire.  For the Manifold, replace TKC 5050 (closes @ 106 C) with TKC5532 (closes @ 102 C).  TR8CCA newsletter, issue 33 (pg 14) Fred Smith mentions that Jaguar part # DAC3061 (XJ6, Later version II, III) fits the radiator threads with cutin/out temps of 96/90 degrees C, which is lower than the stock TR8 switch and will pull the low speed fans on earlier, which might be good. TR8CCA newsletter, issue 46 (pg 3) Fred Smith explains that TKC5532 is a good replacement for the engine mounted (TKC 5050) threaded unit.  There is an alternative version (ERC2864) that bolts in with three screws and was also used on a variety of models. The TR8 with A/C uses one switch on the radiator (M22 x 1.5 threads) to activate the low speed circuit  (cut-in = 93°C, cut-out = 82°C)  and another on the engine intake manifold to operate the high speed fan circuit (cut-in = 108°C,  cut-out = 102°C).  TR8CCA newsletter issue 75 (pg9)  Paul MacDonald mentions that NAPA FS164 ( on 191F and off at 171F) fits in the radiator and works well. He also mentions that NAPA FS101 (on 208-228F and off at 198-218F)  appears to be the correct one for the high speed manifold location. The radiator switches from the 1985 to 1995 Saab 9000's are direct screw-ins for the radiator switch and have temp ranges (cut-in/cut-off) as follows:           1985-1988 92/88°C single range switch.           1994-1998 90/86°C & 106/102°C. Dual range, three prong unit.           1995 100/96°C & 111/107°C. Dual range, three prong unit. 1977-87 Jaguar XJ6 part number DAC3061 95/90°C single range.

Radiator Hose – Top	Application:                          TR8 Triumph Part #:                   GRH 628 (w/ AC),   GRH 629 (non AC) Other Part #’s: Other Vehicles: References:                          thebritishcar.com forum, WWWedge e-mail list. Comments:  “My plan had been to buy 2 hoses, with the appropriate bends on each end, and splice them together. The parts guy apparently had a different idea as he found Gates # 21998. The length is excellent and the bends at each end are right. The problem is the ends are not in the right planes. You might be able to twist it and get it to work but I chose to cut and splice it about 1/3 of the way from the radiator end. Quite a bit of open space to work with there. You will need a coupler with a 1.5" OD, 2-3 inches long. Cost--$20 plus the coupler. (There is a generic brand hose for $11.) SO much better than GRH 628 “ – thebritishcar.com forum “I talked to Darrell Parsons Sales Manager Automotive Aftermarket at MacKay Rubber Co in Australia and they are going to change the GRH 628 (Tr8 LHD AC) hose (MacKay #CH4277) and add 3 inches to the radiator side and 2 inches to the thermostat housing side of the hose....you cut to fit....they are sending me one in the next week or so from Australia ..I believe this will be a production change made to the make drawings for all future parts manufactured and not a new part number-let you know...” – thebritishcar.com forum,  (March 20^th, 2013) “Moss does have that hose (GRH628) in a Kevlar reinforced Mackay Brand from Australia in stock. (Kevin Todd)  The GRH628 is spec'd for PI cars, has anyone used a GRH628 on a carbed TR8 w/AC and if so were the results acceptable?  (Karl Knowles)  I used that hose on my TR8FHC with carbs and AC. It fit perfectly.”   -  Shawn Loseke  WWWedge e-mail list  (Dec, 2014) “The upper radiator hose, GRH628 is for both FI and carb cars with A/C.  Non A/C cars use GRH629”  - Fred Smith  WWWedge e-mail list  (Dec, 2014)

I have done that, but these day, I just drill a 1/8 hole where the jiggle pin should be.” - Jack McGahey  (July, 2015)
