Hi there, Newby here, as per the title, what is involved and how long could it take to replace the radiator that is badly blocked and the engine is overheating.
Thanks in advance
Thanks in advance
Yes they are all boiling hot to touch all the way up to the rad, and even those which goes to a plated heat exchanger for auto transmission, except the two which goes to the internal Matrix, but after I removed the internal Matrix and refitted it they were still cold, so had to remove the hose from the water pump side and fill it up with a water hose until water started to flow out from the reservoir, whilst the hose from the pump was out we temporarily blocked pump outlet, to fill up the internal matrix, once bled, the cabin heated so well, really heated it well, but then the engine temp rose and water started to boil out of the reservoir quite a lot of it, emptying the contents and now as all the water (coolant) is out so the internal matrix stopped giving heat. Radiator fans were on as well, so definitely blocked radiator.When the engine is up to remperature are all hoses hot?
The fans on these generally cut in at 105c (lots of threads about it here) if you are getting boiling coolant at 90c something is wrong., Today experimented with fans not cutting in till after the water starts oozing out of the reservoir bottle, which is what causes overheating issues as the fan seems to cut in pretty late like 90+
Had two caps replaced as this was suggested by someone earlier and it made no difference to overheating and loosing coolant, most people suggested HG gone, but this was litmus tested twice at two different garages.Buy yourself a new coolant tank cap. It is probably not holding the pressure sufficiently, causing the coolant to boil at a lower temperature.
You said earlier you changed the, I ran the engine for at least over half an hour and the temperature never rose above 80C. It may not be the ideal temperature this engine was designed to operate at.
new water pump, new Thermostat mounted on the top front of the water pump housing,
Yes, SXI 1.2 Just to confirm, my Corsa is 1.4, I know another mate who has a similar age Corsa and his one also runs quite hot, one summer he could feel and smell his engine as overheating, but it was not as they run at 105C.You said earlier you changed the
so there is no reason it should be running at 80c these engines are known for running around 105c as mine does.
If the radiator was blocked or partially blocked it would run hotter not cooler than the normal temperature of 105c how can it run at 80c with a blocked radiator?Yes so I will have to now tackle replacing the radiator, no other option mate.
Just to reiterate, car developed overheating problem, using a lot of water over a few miles journey, showed it to many experts, two opinions pointed to its HG, but litmus test was Ok, so another said try new rad cap, so two new caps were tried, they did not make any difference, so one said remove its thermostat from the housing, this was done, car still overheated, so one expert said coolant is not flowing, he made that point on the bases that my internal heater matrix did not heat up the cabin either, so flow problem and pointed to a water pump issues, so this was replaced, the old one was perfect in fact, fans cut in very late so one opined that Temperature sensor may be at fault, so this was replaced with a new one, again it made no difference, so finally there was only one more thing left to suspect and it was a blocked radiator, it was diagnosed as blocked rad, this is when I ordered a new rad, but has not been replaced yet.If the radiator was blocked or partially blocked it would run hotter not cooler than the normal temperature of 105c how can it run at 80c with a blocked radiator?
This whole thread makes no sense to me whatsoever.
This is what I had been waiting for, any information on what is involved, any complications etc that I may have to watch out for, and I tried to search on You Tube for any videos but there was nothing on this, yes I might as well do this properly, instead of messing about with resistors and soap pods, get it done for once and all.That’s fair enough. For awareness the front bumper is actually really easy to get off, I took mine off yesterday in about 15 minutes. A few torx screws on the slam panel, a few underneath, and one in each wheel well that holds the top corner to the arch.
