jad Posted November 2, 2012 Share Posted November 2, 2012 Hi Has anyone fitted a control valve to the coolant circuit of the older engines (pre-tdci) to allow them to heat up quicker? Was thinking of something like the TDCI part ie http://www.brit-car.co.uk/shopimages/products/normal/JQD500080.jpeg or something off of ebay like http://www.ebay.co.uk/itm/251148276472?_trksid=p5197.c0.m619 If you have what did you fit and has it made much of an improvement? The 200 is taking quite a bit longer to heat up now its getting colder! Cheers Jad Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted November 2, 2012 Share Posted November 2, 2012 I wouldn't be surprised if you could fit the old Series part to a 200Tdi, the threads for the valve and the hosetail are certainly similar anyway. http://www.ebay.co.uk/itm/251144770191 The hosetail for the heater pipe at the back of the block on a 200Tdi uses this part: http://www.lrseries....h=624091&page=1 I reckon you could put the Series valve in the port on the back of the head, which would allow you to control the water flow. But I'm not convinced it's worth it. With a properly working thermostat a 200Tdi will heat up pretty quickly. On my 8 mile drive to work, mine's blowing warm 1.5 miles from home and up to temperature and hot by the 4 mile mark. And that's with a viscous fan that's somewhat stuck on!

jad Posted November 2, 2012 Author Share Posted November 2, 2012 Does anyone know if the threads are the same? Is it ok just to block the flow through the heater rather than having a bypass? Land rover thought it was worth it for the TDCI's. Im guessing it would reduce the emissions by having a faster warm up time. I havent timed how long it takes for my engine to warm up but will do next time i drive it but every little helps! Its very cold at 6 45 in the morning!

western Posted November 2, 2012 Share Posted November 2, 2012 my 200tdi is up to temp within 3 miles even in the current cold mornings, no rad blinds or taps in the circuit, have you checked or replaced the stat recently ? Quote Link to comment Share on other sites More sharing options...
jad Posted November 2, 2012 Author Share Posted November 2, 2012 The stat is fairly new as the last one stuck shut and chucked half the coolant out! It was a wax stat. I ordered OEM or Genuine cant remember now. The temp tends to sit at 88 in normal driving in hot weather and 82 in cold weather. Only goes up to 91 when pushing on... The rad is in very good condition, recored with an HD core and I dont run a fan. Maybe I am just impacient in waiting for it to warm up! I did find a thread saying the Series 3 valve was 1/2BSP but cant find what the 200 head is. Cheers Jad Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted November 2, 2012 Share Posted November 2, 2012 I believe the threads are the same. When I put my Series III back together I replaced the old valve type with the plain hosetail from later models and it seemed to fit OK. 1/2" BSP sounds about right, though I wouldn't bet on it!
