VW Vanagon Inline-4 TiiCo/Remtec Transmission Adapter Plate and Flywheel

April 28, 2012

Post #4 in the TiiCo dismantling saga, the TiiCo/Remtec/diesel transmission adapter plate and flywheel. (Remtec was Volkswagen of South Africa’s engine rebuilding division – now a separate entity.)

I’ve read that the flywheel is customized to mate a 1.6(1.9?) diesel or 1.8/2.0 gas engine to the standard gas VW Volkswagon Vanagon transmission with the 228mm clutch. (This one connected a 2.0 3A Audi bubble block to a VW syncro transmission.)

The Tiico transmission adapter plate mounts between the engine and the flywheel and allows the inline-4 engine to be mounted at a 50 degree angle to fit under the Vanagon T3 Transporter deck lid.

Flywheel: stamped 223674 on back, scratched 51 on the hub in the inside, no VW part numbers.

Transmission Adapter Plate: marked 996-100-001BX, but this seems to be a number for an entire remanufactured Remtec (TiiCo) 2.0l inline-4 Vanagon (Kombi/Transporter) engine.

Diesel VW Vanagon T3 Coolant Hoses – Part Three – Heater Hoses

All Vanagons, diesel or gas, use the same heater core.

But once again, the ’82 hoses are different, as the heater shutoff valve is located under the dash, behind the glove box close to the heater core.

’83 and later Vanagons put the shutoff valve under the floor.

See Part One – Diesel VW Vanagon T3 Coolant Hoses – Engine Compartment – for details on how to read the information below:

(23) Heater Core
* ALL 251-265-303C

(9) Heater Hose (Feed) Front Heater Control Valve to Heater Core
NLA 82CS 251-265-053 (valve under dash)
* 83CS+Later 251-265-053C (valve under floor – could be cut to fit 82CS.)

(10) Heater Hose (Return) Heater Core to Adapter Fitting.
* ALL 251-265-054A (under floor)
Note:
my ’82 has both connections under the dash, and used the shorter (NLA) 251-265-053 for both feed and return, as both (9) and (10) are similar at the heater core end.

(11) Heater Hose (Feed) Cylinder Head to Front Heater Control Valve – 3900mm
NLA 82CS 251-265-055B
* 83CS+Later 251-265-055F
82 DIY:
The ’82s have 5/8” hose the entire length, except for a 1” connection to the cylinder head. Alan Felder from the Diesel-Vanagon yahoogroup suggests splicing standard 5/8” heater hose to a Gates 19663 hose (NAPA NBH11663) , which has a 1” end and a 5/8” end and is about 43” long. (Gates 18965 – NAPA NBH10965 also has a 1” to 5/8” reduction but is only 35” long). At $215 (list price 02/2010), the stock hose is pretty spendy.

(15) Heater Hose (Return) From Front – 3530mm – Connects to 3-Way Hose (6)
* ALL 251-265-057 (available but discontinued)
82 DIY:
if this isn’t just a $225 (list price 02/2010) length of 5/8” hose, I don’t know what is! Most folks recommend about 30 feet of 5/8 hose to replace the stock heater hoses.

Not surprisingly, the 1982 Diesel Vanagons have a unique radiator, as gas Vanagons were still aircooled.  The next year, everyone go the same radiator, gas or diesel.  '82s also have a metal additonal metal feed pipe leading to the top of the radiator from the long underbody coolant pipes.  '83s also share the smaller (1.25”) diameter metal coolant pipes, while later gas Vanagons moved to larger (1.5”) diameter plastic coolant pipes.

Diesel VW Vanagon T3 Coolant Hoses – Part Two – Radiator Hoses

Not surprisingly, the 1982 Diesel Vanagons have a unique radiator, as 1982 gas Vanagons were still aircooled.  Starting in 1983, a new style radiator was used for both gas and diesel models.

The ’82s and ’83s share the smaller (1.25”) diameter metal coolant pipes, while later gas Vanagons moved to larger (1.5”) diameter plastic coolant pipes.

Note that 1982 models also have an additonal metal feed pipe leading from the long underbody coolant pipes to the top of the radiator, while the later radiator style uses a rubber hose for the feed from the underbody pipes.

Diesel VW Vanagon T3 Coolant Hoses – Part One – Engine Compartment

February 25, 2010

Most diesel VW Volkswagen Vanagons (and diesel Vanagon Westfalia Campers) in the USA are from 1982, with some 1983s floating around. Both sport the 1.6 liter naturally aspirated (NA – non-turbo) engine. The ’83s have the “newer” water-cooled 5-speed style transmission. Both have a weird, mostly “no longer available” coolant hose system.

Luckily VW continued to sell Vanagon “T3″ diesel models in other parts of the world. These included the same 1.6NA CS engine, as well as a 1.7NA KY engine and a 1.6TD JX Turbodiesel engine. Although these later models aren’t exactly the same, the coolant hoses should fit the USA 1982 and 1983 CS diesel Vanagons with minor modifications.

Note: The 1982 models had smaller diameter metal coolant pipes under the chassis, and smaller diameter hoses leading to the coolant pressure tank. For the 1983 models, VW moved the engine back 2 inches, kept the smaller diameter metal coolant pipes, but used larger diameter hoses on the coolant tank. Later models also had the engine further back, used the larger plastic coolant pipes common with gas models, and had the larger diameter hoses on the coolant tank (also the same as later gas models).

Basically, the 1.7 KY diesel hoses are still available (and the KY 3-way and 4-way hoses are the same as a TiiCo conversion), and should be pretty close to a stock 82 or 83 Vanagon diesel.  The 1.6TD JX hoses are close, but have an extra electric water pump.

(JX3) Note: The JX (and KY with a/c) 3-Way Hose (Return) From Radiator Pipe & Oil Cooler to Water Pump has an ADDITIONAL ELECTRIC WATER HEATER between the 3-way hose and oil cooler.
* JX+(KY with a/c) (JX3) 068-121-073H 3-Way Hose to Electric Water Pump
* JX+(KY with a/c) (JX33) 034-965-561C Electric Water Pump (also needs mount/wiring)
* JX+(KY with a/c) (JX7) 068-121-105 Oil Cooler to Electric Water Pump Hose

Note: Please support businesses that support old VW buses and vans: Van-Cafe in Santa Cruz has a TiiCo set for sale (same as KY except for the $5 bypass hose?) and The Bus Depot in Pennsylvania always has great prices, if somewhat slow shipping – I guess some parts need to come from Germany..  (P.S. thanks to Bus-Boys for the NLA list.)

Cost: You’re looking at $350-$400 (02/2010) for just the engine compartment hoses.  Nearly all of the cost is in the three funky hoses.  Used JX hoses from Germany are available from vanagon.eu (ebay/thesamba seller), while Justin over at Greaseworks sells a “lifetime” silicone set of the engine compartment hoses.

I’m not quite sure what changed between 83 and 84, why some hoses are different from the later KY? Please comment for any corrections or other hose number options!
