fulani 4 Posted January 25, 2008 Driving to work this morning, the temp gauge is fluctuating all over the place. Oil pressure gauge is not working, so can't check that. There is a small amount of heat coming through the vents, so heater matrix is OK. Very thin scraping of white in the oil filler, no worse than I've seen on a perfectly healthy engine. I took the coolant filler off, and it exploded hot air all over me, with a little bit of water. It then gurgled for a while, no obvious leaks. There is water left in the header tank, but not much. I have had the inlet manifold (and therefore coolant) replaced recently. Reckon it's just an airlock? Or something more sinister? Thermostat? Head gasket? Ah!!

fulani 4 Posted January 25, 2008 ...any help would be greatly appreciated. At the moment, I'm thinking top it up with some water, and see what happens? Share this post Link to post Share on other sites
rallyeluke 0 Posted January 25, 2008 ...any help would be greatly appreciated. At the moment, I'm thinking top it up with some water, and see what happens? sounds like airlock to me. did you bleed in the correct order with heaters on full blast while filling?

fulani 4 Posted January 25, 2008 Didn't bleed anything, it just gurgled a lot. I assume the bleed points are in the Haynes manual?? Share this post Link to post Share on other sites
yorkshirekowboy 19 1 Cars Posted January 25, 2008 (edited) ...any help would be greatly appreciated. At the moment, I'm thinking top it up with some water, and see what happens? deffo a air block, get it sorted thou as his can lead to head gasket failure, trust me i only find youonly need to bleed the near the bulk head, right of brake servo, the thermostat housing seems to sort itself.

Miles 331 1 Cars Posted January 25, 2008 Fill it up and bleed it off but 205's are pretty good for not needing much of this at all, When it's filled back up check to see if there's any bubbles in the header tank with the engine running, if not the HG should be OK, Is the oil level OK? Mayo in the oil cap? Share this post Link to post Share on other sites

Mayo in the oil cap? Oil level is fine, as I said, a thin layer of white in the oil cap, but no worse than I've seen on otherwise healthy engines. I'll run it halfway home, check and top up as necessary, and properly bleed it tomorrow. Share this post Link to post Share on other sites
fulani 4 Posted January 25, 2008 Made it all the way home, faultlessly. Even stuck in 2 hours of traffic (anyone else stuck on the A34/M3 today?) it was fine. No water lost on the journey. Looks like I was getting worried about nothing. Cheers for the advice! Share this post Link to post Share on other sites
fulani 4 Posted January 31, 2008 Right, I think the air lock explosion has holed the heater matrix. Let me explain. There's water in the driver's side footwell. Carpet is soaking. I have just been to the car wash though, could be a leaky door seal? Stereo has been playing up the last couple of days, it's an old tape unit anyway, so take it to Halfords to get a nice new Bluetooth CD playing one fitted. The guy (free fitting) gets the old head unit out of it, and it's soaking. The ISO adaptor is wet and corroded. Everything in the now vacant slot is wet. Weird thing is, very little water (if any) has been lost from the header tank, and passenger footwell is dry as a bone. Current plan is - let mats and footwell dry out in garage, take car for a spin in the dry with the heater on. Check for dampness. If none, take car back to carwash. Check for dampness. So I reckon that will tell me if it's the heater matrix, or a weatherseal leak. Good plan? Share this post Link to post Share on other sites
Super Josh 4 Posted January 31, 2008 Well if the stereo is wet then that's a telltale sign that the heater matrix is leaking. Josh Share this post Link to post Share on other sites

applemobile 0 Posted February 1, 2008 best way to tell were a fluid is from is to taste it! i presume you used a 50% coolant mix, its gonna taste pretty strongly off antifreeze if it is. If its from a jet wash, it should taste like refreshers im my expirience! Share this post Link to post Share on other sites
