Thanks for all the help, plan of attack is to work my way round the coolant system with hose pipe to try and find any blockages. Will also remove thermostat in that procedure to be thorough. Might not get round to it until the weekend due to having no light after work.
Just ordered a new expansion cap, for a few quid I'd rather discard that as a possible issue. Will update as and when at the weekend Wayne |

Hopefully it will just be the thermostat stuck shut, possibly the radiator is blocked too mate, worth a check

Pressure cap is also a good-call. Hope you find it mate and sure you will if all bases are covered. My money's on the thermostat.

Top (inlet) hose should be smaller in diameter, bottom (outlet) should be larger.
That housing with the glow plugs is an auxiliary coolant heater which, I imagine, is available for colder climates. It's not on my S40 either.

Well, a totally unproductive few hours, left me scratching my head and kicking the imaginary dog in frustration.
Im gonna ask a completely obvious and stupid set of questions as now I cant see the wood for the trees and am doubting everything I do. Took off rad top and bottom hose and hosed it through top to bottom, totally clear and flowing. Then removed the thermostat, on putting it back together the housing wouldn't seal without a thermostat in it so that kinda knackered that idea. tried it with the seal alone but wasn't sealing. Did notice that it was a gen Volvo one that was fitted, with the mentioned nipple for orientation. It was looking a bit past it, the seal was all chewed up so decided to replace. The new one from Euro Car Parts doesn't have a nipple or any way of telling which way is up or down. Threw that in and it sealed but seemed to make no difference at all. There doesn't seem to be a proper circulation, so stupid question no 1. on following the hose from exp tank it goes down the inner wing then into a T piece that splits, one way to rad bottom hose connection and other to front off engine block, oil cooler pipes etc So does the flow go into bottom of rad and out the top or vice versa? I always thought it was in the top and out the bottom, but im blind now with frustration. Car isn't overheating but isn't getting a return supply to the expansion tank at all. So where to now, as ive bled it and bled it, had every pipe just about off and still no wiser can anyone send me an idiots copy of the vadis diagram with flow direction or just tell me which way so I don't go bonkers. I hate this car now! |

Did you find the problem I have exactly the same symptoms on my v40. Have been all over it everything points to a blockage in the coolant but cant find it.
