StephaneM Posted September 15, 2003 Share Posted September 15, 2003 Hello, I have a problem to fit my jenvey TBs to my Vx engine. My car is a Lhd & one part interfere with the alternator bracket... It won't be very easy to find another way to fix the alternator if I have to keep the part... So the question is: Do I have to keep this part? my "garagist" said me that I don't need coolant fluid return (he fits a cap on it), like on carbs car, but I'm not sure... I don't know if this part is there for others cars applications... You can see pictures here: http://stefanauto.chez.tiscali.fr/RQ/2_my_bracket.JPG http://stefanauto.chez.tiscali.fr/RQ/8_needed_or_not.JPG Thanks in advance Stéphane in France Link to comment Share on other sites More sharing options...
John Howe Posted September 15, 2003 Share Posted September 15, 2003 Stephane, not 100^% sure I understand the question. but if you are suggesting doing away with the return feed for header tank from the throttle bodies, I understands that this can be done away with... well that is what DVA told me about 4 years ago. ...but if your problem is the alternator brcket, why not change the measurement of the bracket and use a belt that fits the new space? I'm sure a Vx expert will come along and give you better guidance JH Deliveries by Saffron, the yellow 222bhp Sausage delivery machine Link to comment Share on other sites More sharing options...
EFA Posted September 15, 2003 Share Posted September 15, 2003 John, It is the water elbow on the inlet manifold which intereferes with the alternator. I am not sure if this outlet can be closed off, as it actually provides a draw oin the coolant in the head into ythe water pump. DVA's comments whilst indicative I would guess are targeted at the K not the VX??

Nick Pargiter Posted September 16, 2003 Share Posted September 16, 2003 Stephane We had a new coolant take off pipe machined up to replace the cast one. It is only 50mm long and takes 15mm I/D hose so should give you the clearance you require. Sorry I haven't got a picture but will e-mail you a drawing.

StephaneM Posted September 16, 2003 Author Share Posted September 16, 2003 Thanks Nick! But will I have to connect this to the cooling network or will I have to use a rubber cap as in my picture??? If I have to connect it, where is the best place? thanks. Stéphane in France Link to comment Share on other sites More sharing options...
Nick Pargiter Posted September 16, 2003 Share Posted September 16, 2003 Stephane We have a pipe connected to the aluminium submarine pipe in the bottom hose from the radiator. We had thought about blanking it off but were told that it upsets the coolant flow/temperature across the cylinder head.

Marius Posted September 16, 2003 Share Posted September 16, 2003 Some more thoughts to perfect confusion: When I ran Webers on my VX this "hole" in the inlet-manifold was defintiyl blanked off, seemed to be like this on every standard HPC. I went on to Jenveys then using a similiar brackt like yours. The hose from the bracket goes directly into the inlet of the waterpump but we we found out that because of this bracket it´s b**** job to remove air out of the coolant system. Does anyone know about the function of the hole behind the bracket ? Does it provide cool water for the head or does it remove hot water ? I remeber seeing a Swindon engine with this hole closed on the manifold. Would save weight, too. 😬 Marius Link to comment Share on other sites More sharing options...
StephaneM Posted September 16, 2003 Author Share Posted September 16, 2003 So, my cap machining is in progress... Do you think there is a risk for my engine? (but I will also have a look on neil drawing...) cheers Stéphane Link to comment Share on other sites More sharing options...
StephaneM Posted September 20, 2003 Author Share Posted September 20, 2003 some news! I did that: http://stefanauto.chez.tiscali.fr/RQ/lhd-alternator-bracket.JPG So now the alternator is fitted... & I try to install the accelerator câble in order to have only 1 180° turn... it is not so easy due to the chassis tube & the alternator... but I think it will be OK... I will phone SBD next week to be sure that I can take this part away 😬 because it seems they are too busy to answer to my e-mails (I can understand of course, They are not here only for me... it's only easier for me to understand written technic english instead of spoken one...) cheers Stéphane in France.

Chelspeed Posted September 20, 2003 Share Posted September 20, 2003 My understanding is that this hole from the inlet manifold is designed to take hot water from the head back to the pump inlet when the thermostat is closed. When the thermostat is closed it stops water flowing to the radiator but opens up a passage across the head and back to the pump inlet. This means water flows through the head while the engine warms up. When the thermostat opens it closes off the water flow back to the pump suction via this hole through the inlet manifold and opens the flow to the top of the radiator. If you run with no thermostat then you must blank off this hose otherwise water would rather flow through here than through the radiator. It's possible that if you see an engine with this hose blanked off that it has no thermostat fitted for some reason. Just because you have seen this doesn't mean it's safe to do on all engines, check with someone who knows a bit more than me, SBD, QED or Swindon.

EFA Posted September 20, 2003 Share Posted September 20, 2003 Marius. My Morgan (read: HPC with flared wings) definately has the hose from the head to the sub tube fitted. I think Graham is right that this pipe provides limited water circulation before the thermostat opens, but I do not think this path closes with an open 'stat. It might have a reduction in flow, but it doesn't close. Anyway, bottom line is that I'd leave the pipe in place. Blanking it may well lead to future trouble.

StephaneM Posted September 21, 2003 Author Share Posted September 21, 2003 I will phone SBD tomorrow. But I cannot understand why there is not this return on carbs cars, even with high level of power... cheers. Stéphane Link to comment Share on other sites More sharing options...
Marius Posted September 22, 2003 Share Posted September 22, 2003 The induction manifold was a bit different but I´m not really sure about this. But now I´m starting to understand where my temp-problems might come from... Stephane, please let us know what SBD sais. Marius Link to comment Share on other sites More sharing options...
