Welcome to OOF
Heater matrix is also a possibility. I currently have similar symptoms due to a small leak at the matrix.I would have thought you would have smelt it if it was heater matrix?
Which reminds me, I really must get off my arse and replace i soon.
Only use it occasionally, so havent been desperate to do the job.
They always go faster with a fresh MOT!But still not as fast as a hire car. Even if it is a 1.2 Corsa, with a turbo, apparently.
It was all the reading you did when in hospital for ages. Stick to that excuse, saddoI remember The Sweeney using the MkI Consul but didn't pay any attention to badging was it the 3000GT model they used?
Yes, I believe so.The 3000GT Consul was eventually replaced by a Granada 3.0S before the later MK2. I really do need to get out more.
There did appear to be a duff batch a few years ago, a few people, myself included, got caught out........
HBV is quite new so not suspecting that either.
I wouldn't completely dismiss the HBV, as my original on my 3.2 lasted around 80K miles but it's replacement lasted less than 5K miles. The replacement was purchased from a main dealer and the box had the hologram on it. The second replacement was still OK when I sold it. Worth checking using the max high temp, max low temp method.
IIRC, over half of the ATF is retained in the torque converter. So you will only drain c.3.5 litres of oil first go.LOL, snap. Typed at the same time
So....in my understanding....first oil change gives a 50% ratio of old to new, second one gives you 75%, third one gives 87.5% and so on. So 10.5 litres of ATF will, more or less, give you an acceptable ratio.
Mk2 then thats okay, worked on loads back in the last century!You mean last millennium
. I'm sure anyone wanting multiple items will PM you for a bulk buy bargain
