Radiator Expansion Water Tank Cap Compatible for Fiesta Focus C-Max Mondeo

Product Information

As well as the temperature issue, the engine seems to start struggling, stuttering/jerking a little when I am pulling away from idle or accelerating (particularly in low gears) after I have been driving for about 20-25mins, although varies depending on how hot of a day it is so I assume this relates to overheating? The motion is similar to that when you're close to stalling but not quite as bad yet. A colleague has suggested that it could be head gasket related, however this was previously ruled out by a mechanic (and I have hoped and prayed that it isn't as I don't want it to conk out entirely one day on my way to work/home). Any advice would be greatly appreciated as I am desperately trying to keep the car going until Sept/Oct when I will be looking to replace it altogether. The reservoir has a fill range marked on the side. If your engine is cold, the coolant level should be up to the cold fill line. Only reasonably practical desperate improvisation I can think of would be removing the thermostat. This will potentially increase circulation in the cooling circuit, allowing it to remove more heat. Open the hood and locate the engine coolant reservoir. It is often a translucent white color, and has hose(s) connecting it to the radiator. I suppose you could “tune” it with a blanking plate with a hole in it, to provide less but still some restriction.

IIRC, the OP did not tell us the reasons for the water pump replacement, referring only to a coolant leak, but the reservoir blowing was said to follow-on from it, Roll up or remove loose clothing, and keep your arms away from the cooling fan(s). Fans can turn on automatically, even when the engine is off. Note that I’m assuming a “classic” mechanical thermostat here. If its something more modern, perhaps controlled via satellite downlink from a CIA Cray Supercomputer at Langley, this may not be possible.) The OP is unlikely to want to bother with that though, especially as he already has some blowing from the coolant reservoir so couldn’t easily detect any local boiling due to modification.

If you are not loosing coolant I too doubt if you have a head gasket leak. Yes the garage can test for gases in the coolant but if you have a leak then if the gas comes out into the coolant then coolant would pass the same way when stationary. and be lost.

It will however, also slow your engines warmup times, and if you’ve got any starting difficulties now, perhaps from a bit of coolant getting into the cylinders, they’ll probably get worse. This may be tolerable, at least for the summer. renewed on my diesel car last year and found the reservoir empty when I got home - the techy just hadn't run the engine enough for the thermostat to open fully. You can sometimes score extra cooling using the aircon fan (I ran my Sierra using the aircon fan only for a while) but I assume if you had one you would already be using it

I have a couple of fridge compressors that I could try, but I'm getting used to the boiling method so I probably won't bother..

I did, however, realise that there are sometimes no bleed points, because I think that's all I've ever had on any of my cars. Can't remember it being a problem before. I've done this a few times now on the Skywing. I don't much like doing it, but I think its less risky than your suggested laissez faire air alternative. In the winter, engines need to be stopped from freezing up and causing irreparable damage. You may need a replacement car cooling fan, car radiator, expansion tank, or intercooler, and at Halfords we’ve got it all. Car Air Conditioning Coolant also helps keep your engine working as efficiently as possible, helps keep its emissions low, and even helps provide that toasty heater air on cold days.When your engine is running, it makes power—but it also makes heat. And that’s where engine coolant comes in. Clarkson cut holes in his classic Range Rover bonnet on the Bolivia Special to ameliorate an overheating problem, but that would affect resale. Less permanently you could remove the whole bonnet, but I donno how legal that would be in the famously anal UK. If you had a water pump failure its a fair bet you had overheating. Head gasket or head failure is a common consequence of overheating, so no big surprise there. Your car’s heating and cooling systems are important factors in having a comfortable ride all year round, but especially in extremely hot or cold conditions. Car Cooling System

I can’t say that doesn’t happen, but I would have thought it was fairly unusual, since thermostat removal is/was quite a common bodge/workaround for overheating problems. Never remove the coolant reservoir cap when the engine is running or still hot. Let it cool down first. If you need to repair your car’s air conditioning, we have all the parts you could want, including accumulators, actuators and compressors. IF the water pump is belt driven, I suppose it might be possible to change the pulley to increase the pumping rate, but I doubt it would be worth the trouble.Further to my last post, the bubbling coolant has continued but in all honesty I am not too fussed as long as the car can last me another 3-4 months. My main concern is that if I drive it without the internal fan on to accommodate for some of the extra heat, the temperature of the engine (on the dashboard, at least) begins to very slowly climb above 90 degrees. It remains on 90 if I keep the fan on, but the engine fan creates a hell of a noise (not that it matters if it is working). Now it is getting towards summer I am starting to get fed up of absolutely roasting in my car every time I go to/from work so am looking for an answer, however, given my problems with previous mechanics and the fact that I have already paid out a few hundred pounds on this issue I wanted to ask the advice of you guys before having a paid mechanic come and look again. Make sure your engine is off and cool, the vehicle is in Park or Neutral, and the parking brake is set. If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself). You can use diluted coolant by itself or a 50/50 mixture of concentrated coolant and distilled water. If there was no overheating, the water pump replacement is a bit suspect, but is unlikely to have caused a head gasket failure, which seems to be suspected by the OP. IF you aren''t losing'coolant, I don't quite see what the leak stopper is for. I suppose if an undetectable amount of coolant is passing into the combustion chamber some leak stopper would be drawn in too, but it doesn't seem very likely to seal against combustion pressures.
