Guest Buddman Posted January 16, 2005 Report Posted January 16, 2005 Help!!!! Garage can,t but can you!! I have a gal 1.9tdi The front heater gets hot than goes cold intermittently, any idears! (ps have not checked the rear heating) Quote
Guest vr6galaxy Posted January 16, 2005 Report Posted January 16, 2005 Do you have CC or standard heating? does the aux heater cut in? does the temp gauge on the dash move in time with these temperature changes? can you smell anything unusual from the air vents? are you loosing coolant? does the engine come up to temp and stay there? does the rear heater get hot and stay hot while this happens? do the hoses to the front heater unit get hot? and do they stay hot? I think that should do for starters? :) Quote
Guest Buddman Posted January 16, 2005 Report Posted January 16, 2005 Thanks for your replyto answer your questions1.Galaxy 1.9tdi (2001)2.standard ac3.Engine up to temp (90) around town ok but on long trip overheats quickly than back to 90!! and yes odd smell from ventsWill check your other sugestions tomorrow Many thanks Graham Quote
Ivor_E_Tower Posted January 17, 2005 Report Posted January 17, 2005 Sticky thermostat and possible air lock? Quote
seatkid Posted January 17, 2005 Report Posted January 17, 2005 Overheats quickly...no heater....ummmm....What I would do is... 1. Get the system pressure tested to check for leaks (which is where the funny smell maybe coming from [heater matrix]) 2. Change thermostat - check old one was opening (if not leads to overheating and possible no heater) 3. Change water pump - does anyone know if this model is one of those fitted with plastic impeller? [prone to break off shaft]) If that dont fix it, I dont know what will.. Quote
Ivor_E_Tower Posted January 17, 2005 Report Posted January 17, 2005 Pressure test is definitely a good idea. Quote
Guest Buddman Posted January 17, 2005 Report Posted January 17, 2005 Thanks for your reply Garage has already performed a Pressure test and a chemical test both appear to have past. Alson I have noticed no heat from front or rear blowers (fans ok) plus bottom radiator pipe is cold!! any idears Quote
Masked Marauder Posted January 18, 2005 Report Posted January 18, 2005 Air lock. The garage should have spotted it. You need to fill the heater matrix up through the heater top hose. Quote
Guest Buddman Posted January 18, 2005 Report Posted January 18, 2005 Thanks for all your replys They all sound like possible reasons why its overheating. The garage has suggested, first they change the thermostat, if this doesn't cure it then the water pump.Perhaps I should suggest to them a possible air lock!!. Iwouldn't be surprised if they carry on changing parts just to get more cash out of me! :lol: Will report their findings. Quote
Guest Buddman Posted January 25, 2005 Report Posted January 25, 2005 For any one else out there. The problem appears NOT to be stat, water pump but a possible air lock!!! Should have listend to you guys and checked it myself!! Garage charged me Quote
seatkid Posted January 26, 2005 Report Posted January 26, 2005 Well, you (I) learn something every day :) I feel under some obligation to point out that if a garage drained your system (causing the air lock in the first place) it was their responsibility to fill it and bleed it properly. Quote
Guest Buddman Posted January 30, 2005 Report Posted January 30, 2005 Problem back again!!!!! No heating Over heats almost straight away. I thought the garage had sorted it, I can't think want else it could be but an air lock again, But how is air get in. Your thoughts would be very much appreciated. Quote
Guest MATT Posted January 30, 2005 Report Posted January 30, 2005 take it back and give them what for!http://www.digitaldreamland.org/content/samples/design/angry.jpg Quote
Guest Buddman Posted January 30, 2005 Report Posted January 30, 2005 They are going to get it with both barrels!!! But I just want the problem fixed, they don't seems to know what to try next. Quote
Guest MATT Posted January 30, 2005 Report Posted January 30, 2005 is it a ford garage? or private your dealing with? Quote
Ivor_E_Tower Posted January 30, 2005 Report Posted January 30, 2005 Any sign of a leak? Are you having to top the cooling system up? - is the expansion tank cap correctly fitted and has it been checked to make sure it only opens under the correct pressure? Quote
Guest Buddman Posted January 30, 2005 Report Posted January 30, 2005 Hi IvorNo sign of a leak, and yes I do have to top up the water level! How can I check the expansion tank cap!! back to garage! Also I have noticed when I check the level the expansion bottle is almost full but if I release the pressure by removing the cap the water level drops!! Quote
Guest vr6galaxy Posted January 30, 2005 Report Posted January 30, 2005 When they pressure test the coolant system the expansion bottle cap is removed so as far as I know it's not part of the test! check out the rubber seal around the cap, if it shows signs of wear or folds around the seal then replace it Quote
Masked Marauder Posted January 30, 2005 Report Posted January 30, 2005 Hi IvorNo sign of a leak, and yes I do have to top up the water level! How can I check the expansion tank cap!! back to garage! Also I have noticed when I check the level the expansion bottle is almost full but if I release the pressure by removing the cap the water level drops!! That is so indicative of an airlock. The build-up of pressure in the airlock forces the coolant into the bottle, release the pressure and the water goes back into the block. Quote
Masked Marauder Posted January 30, 2005 Report Posted January 30, 2005 The fill & bleed proceedure is to fill the bottle to the max mark and with the cap off run up to normal operating temperature and then for a further five minutes. Personally I would run it until the cooling fan came on as long as it was not boiling up. Allow the engine to go cold then top up the bottle and replace the cap. Quote
ridway Posted February 5, 2005 Report Posted February 5, 2005 I have a slow coolant leak on my 2.3 petrol. I have had the leak for about six months and it is in the thermostat housing. I have a new one but havent got round to replacing it yet. My heater goes cold as the level drops below minimum but only when idling. Topping up cures the problem and I have never needed to bleed the system. From your symptoms I suspect there may be a small head gasket breach forcing gas into the coolant and causing an overpressure which may be blowing off the coolant and leaving a vapour lock. I hope you problem is not this drastic but it sounds suspicious. The coolant smell could be from when the filler is venting at overpressure and infiltrating into the air inlet; they are very close to each other. Rich Quote
Guest Buddman Posted February 7, 2005 Report Posted February 7, 2005 Well galaxy back in garage today, just phoned and said chemical test suggest head gasket problem ( Quote
Ivor_E_Tower Posted February 7, 2005 Report Posted February 7, 2005 ...so ask them how much they'll give you as a trade-in :angry: Quote
