Hi, Having been for an extended run, I now of the opinion that the heater radiator is not filling up. If you add water to the radiator header then run, it does not appear to filter through to the radiator.
How do others fill their heater matrix, do I need to take a hose off and back fill it using a hose from the mains. Or do I need to fit a filling point in the system. Haynes manual is as good as a chocolate fireguard. Bill
The conventional set up is a 1/2" heater hose pipe from the back of the head across to the right hand side heater matrix stub then a shorter pipe from the left hand side heater matrix stub to the water pump adjacent to the thermostat bypass hose The the connection at the back of the head is usually a simple quarter turn brass tap - the leaver being horizontal for off (i.e. stops the coolant flow so no hot water to the heater) and vertical for on - sometimes its not a tap but a simple brass stub (i.e. heater would be on all the time) - the simple brass stud was used on 850 engines because they had a heater on/off thingy fitted elsewhere in the circuit
Even though the heater is higher that the main radiator it definitely takes care of itself ...there are no need / no instructions for filling it or bleeding it however, perhaps there is an airlock in the heater matrix? (I've never come across this problem) ...but a solution could be (with the heater tap on) loosen the pipe clip at the water pump and check if coolant is being pumped through the matrix - if not then either no coolant is being sent from the back of the block or the heater matrix is clogged up (I think that I may have heard of heater matrix being completely blocked with silt / corrosion).
I presume that a thermostat is fitted ...water flow through the circuit as a whole is somewhat compromised unless a thermostat is fitted
bondbug750, Thanks for the quick response, I have the pipework set up as you suggest, there is no heater valve, on all the time. The heater matrix is out of the car at present for other reasons, a new fan being fitted...its from China used for cooling oil radiators on quad bike etc...will report after next trip but at present it's blowing well. With the matrix off line I've had the engine running with a bypass rear head to heater return, and the coolant is definitely passing through the pipe. Will go out now and check if matrix has obstruction. Thanks again Bill
bondbug750, All back together now and the next run out is planned for the end of the month...me taking her indoors off on holiday...that's nice, she's paying too...lol. Had the engine running and all seemed well in the yard the hoses appeared to heat up so here's hoping my thoughts were nothing.
For ages I have been developing a "Squint" and a third hand, as I try to view timing marks and hold Glasses in place as I jiggle the distributor body. Then in my various readings I came across a note that some engines are fitted with TWIN timing marks. A quick rub with a rag and lo and behold my engine has them. All you need is a ramp and wiggle under and you can view the marks for cylinders 3 and 2. Start engine and the strobe is dead easy to use, now training my eye to look forward again. All I need is a competent person to move the dizzy, maybe the wife will help!!!
bondbug750: Mk2 ...oblong - but not the same as Bug - I'm racking my brain to guess what part bin they came out of :-( - but I bet it's Mk1 Ford Escort - or Vauxhall Viva late 60's

bondbug750: CBF819H was chassis no. 1 - the first production Bug ...famous (infamous) for its use in the so called Carnaby Street Lord John advertisement - I guess what you've got is the 2nd production Bug!

Little-John: I watched Mike and Eddd. restore a Bond Bug on "Wheeler Dealers." At the Woburn 40th birthday party there were two very professional looking 4 wheel Bond Bugs (one yellow, one green.) Were they factory versions? How were they done? By whom?

mybug: Anyone know the whereabouts of PTO 365M? It was mine back in the early 80s and some pix have surfaced here (apparently from ebay around 5 years ago) so is it still around?

karl: Andrea, just seen your post. if you're still looking try putting it in the for sale wants thread.
Jan 14, 2019 19:58:09 GMT
mybug: Searched and spooled through every image/video/old ad I can find on the internet, I'm thinking that PTO 365M is not around any more. May be resting in a shed, but given the small and tight-knit Bug community, I'd have thought that someone would know it.
