andyl Posted March 18, 2018 Share Posted March 18, 2018 Sorry about this but:-1) Does it run an ECU?2) I presume that the Weber chokes are not connected?3) I have bought a heater on here, does anybody have either a manual or an extract of a manualthat will show me how to connect it to the cooling system?4) Is there a service manual out there that will help me see my way around it?Thanks in advance Andy Link to comment Share on other sites More sharing options...

AdamQ Posted March 18, 2018 Share Posted March 18, 2018 My first 7 (bought in 1999) was a VX engined car - this is going back a bit, but I'm reasonably certain I remember correctly ...1) Does it run an ECU?Yes - it's mounted on the scuttle bulkhead close to the steering column from memory.3) I have bought a heater on here, does anybody have either a manual or an extract of a manualthat will show me how to connect it to the cooling system?I retro-fitted a heater to mine - all I can remember is that a three-funnel submarine and a load of 5/8" ID (I think) rubber hose was required - and a bleed tee is probably a good idea. I might still have the submarine - I'll check tomorrow.Not very definitive I'm afraid, but some help I hope ...Adam Link to comment Share on other sites More sharing options...
Keith_T Posted March 19, 2018 Share Posted March 19, 2018 Adam is right about the ECU. On my 1998 1.8VX it was an MBE but dont have a record of the number. My local rolling road man found the aged software incompatible with his kit. The car came with a heater which we hardly ever used. A bigger issue was dealing with excess heat particularly in the passenger footwell - we seemed to fix that eventually with loads of insulation on both sides of the bulkhead. I found a Haynes Manual in Oxfam which gave details on processes like changing the cam belt. Link to comment Share on other sites More sharing options...
andyl Posted March 19, 2018 Author Share Posted March 19, 2018 Adam I wondered what you were talking about ( 3 funnel sub) now I have a manual I can see!Yes if you have a submarine for sale I would be interested, do you know where the other heater connection is connected too?Regards Andy Link to comment Share on other sites More sharing options...
ECR Posted March 19, 2018 Share Posted March 19, 2018 I have a 2.0 vx but I think the plumbing might be the same. From distant memory ( I don't now have a heater) one connection goes from the front of the head to the 3 way submarine and the other to the rear of the head. You need to plumb a heater control valve into the latter pipe. Others will verify ( or not ....) Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 19, 2018 Member Share Posted March 19, 2018 The manual has different diagrams for the cooling system between fuel-injected and carburetted Vauxhall engines. And the submarine pipes are different.Jonathan Link to comment Share on other sites More sharing options...
AdamQ Posted March 19, 2018 Share Posted March 19, 2018 Andy, Apologies for the delay - I've just looked and I'm afraid the submarine I have only has one funnel - sorry about that ...And I remember being similarly bemused by all this talk of submarines and funnels when I was in a similar position to you!

MADMALC Posted March 19, 2018 Share Posted March 19, 2018 Item 2: Correct the choke is not used. Just pump the accelerator 5 or 6 times to prime the carbs prior to starting. Link to comment Share on other sites More sharing options...
Wrightpayne Posted March 19, 2018 Share Posted March 19, 2018 My 1998 build manual has an amendment section for the 8v vauxhall incl cooling circuit with and without heater.If you send me a pm with your address I’ll copy/post it or better still an email address and I’ll scan it and send.RegardsIanPS - thats the vauxhall amendments not the whole manual :-) Link to comment Share on other sites More sharing options...

andyl Posted March 20, 2018 Author Share Posted March 20, 2018 ECR I just have a diagram from Caterham, one hose goes to the drivers side lower water pump outlet and one to the upper outlet. Link to comment Share on other sites More sharing options...
paul_w Posted March 30, 2018 Share Posted March 30, 2018 Hi Andy - do you know if your car has had a thermostat added (sorry if you've mentioned this in other threads)? If you want the heater to work you'll need one! I followed the advice in post #13 in this thread:https://www.lotus7.club/forum/techtalk/vx-16-8v-thermostat?page=1which didn't need the submarine pipe, just a long piece of small hose and the stat. It worked fine for me for 10,000 miles in all weathers.I bought one of thesehttps://www.ebay.co.uk/itm/VAUXHALL-THERMOSTAT-GENUINE-NEW-90232012/152314376299?epid=1327089471&hash=item2376a4f06b:g:eMQAAOSwx2dYJfPOand drilled a small (3mm from memory) hole in the stat as a bypass before doing the hose mod.The other advice I have is to keep an eye on your water pump - mine lunched its bearings even though the car had only done about 6k miles and I was lucky it didn't take the cambelt with it.
