acaie Posted March 8, 2013 Report Share Posted March 8, 2013 Can anyone help me find a top hose for my Grinnall V8 ? The Rimmer TR7V8 offering I bought looks designed for a horizontal outlet from the thermostat housing, whereas mine is cranked upwards at 45 degrees? Please see attached photo. Does it come from an SD1? Something else? Thanks Al Quote Link to post Share on other sites
Alec Pringle Posted March 8, 2013 Report Share Posted March 8, 2013 Hi Al, presumably they have supplied you with a TR8 hose GRH629, whereas it looks like you need SD1 3500 hose GRH537 . . . . ? I think those are the correct numbers, but you should be able to check on the Rimmer's website. Cheers Alec Quote Link to post Share on other sites
acaie Posted March 8, 2013 Author Report Share Posted March 8, 2013 Thanks Alec What I have is GRH629 - I'll try a 537. Best wishes Al Quote Link to post Share on other sites
Guest Wayne S Posted March 8, 2013 Report Share Posted March 8, 2013 I had trouble with this for my Grinnall but ended up fabricating my own from top grade red silicon hose and a stainless steel joiner pipe. Quote Link to post Share on other sites
acaie Posted March 8, 2013 Author Report Share Posted March 8, 2013 Thanks for this Wayne. I've cut the old pipe and put in a bleed valve using a revington adaptor. I can recommend the bleed valve as making bleeding dead easy. I'm going to get an SD1 hose to see if it fits and because I would like to have a spare to hand. I'd originally planned to do this with a new hose, and keep the old as a spare. I think that if push comes to shove I can put together something with 2 x 90 degree elbows, a 45 degree elbow and a straight pipe, and it's good to find someone who's been down this road and made it work. When I get this sorted, I am likely to embark on the exhaust project you've taken an interest in. Best wishes Al Quote Link to post Share on other sites
Guest Wayne S Posted March 11, 2013 Report Share Posted March 11, 2013 (edited) Al, Here's a pic on my engine bay where you can just about see how the top hose is fabricated. One 90 degree section off the thermostat housing. Then a flexible section (reinforced with wire coil to make it bend not fold) to the radiator. The sensor for the electric fan also screws into the stainless steel joiner pipe. Looks neat and has lasted very well, still in new condition nearly 4 years later as you can see! Do keep me posted on the exhaust project, Best regards. Edited March 11, 2013 by Wayne S Quote Link to post Share on other sites
acaie Posted March 13, 2013 Author Report Share Posted March 13, 2013 Smart. What thermostat do you use? Best wishes Al Quote Link to post Share on other sites
knortech Posted March 13, 2013 Report Share Posted March 13, 2013 (edited) Acaie I am currently running an 82 c thermostat. This is a Wahler large bore dia from a TVR griffith. Temperature gauge runs steady just over 1/2 , But i have an alifab alloy radiator with a 16" puller fan. The temperature creeps up in summer traffic but the fan cools the engine down and switches off using the revotech electronic switch, The engine is also 5ltr from v8 developments. Top hose on my engine is made from a combination of silicone with the sensor in the top hose , I have no distributor in the way (using coil packs) so I have a custom made thermostat housing that is straight out thus avoiding the kink upwards you get to avoid the distributor. The offenhauser manifold also has a capillary temperature sensor fitted for a more accurate reading.If you want any pics just email keith1alex@hotmail.com Edited March 13, 2013 by knortech Quote Link to post Share on other sites

knortech Posted March 14, 2013 Report Share Posted March 14, 2013 The engine was dyno set up by ray webb at V8 developments at 300bhp on the print supplied with the engine. Quote Link to post Share on other sites
acaie Posted March 15, 2013 Author Report Share Posted March 15, 2013 Thanks for this stuff. I've started another topic on the thermostat side of things because it intrigues me why some of us need to use a 74C thermostat. Best wishes Al Quote Link to post Share on other sites
