advice please overheating

[LeeT5]

neat H2o will not cause an engine to overheat mate, fact.

not good if left in there permanantly tho.

just trying to save you wasting £££££

Correct, note i never said it would! But if you had a leaking cap and neat water in your system then i also garantee the car would overheat on a run, probably not at idle in the driveway but drive the car and it will overheat.

Water boils at about 92 degrees C, atmospheric pressure sea level. So a leaking cap will not pressure up the system and thus the engine will boil over cos the engine will get hotter than 82 degrees (thermostat opening) on a run, but probably not at idle. Add a working cap, boiling point raised to approx 97 degrees, add 50/50 mix glycol and it will go up a further 8 degrees thus boiling point is now approx 105 degrees. Now the coolant cannot boil and further increase the pressure and cause it to boil over!!

Wasting pounds is spending money on headgasket work and replacing associated parts when the fault has not even been diagnosed properly in the first place. Doing the job properly or investing in the proper kit will save expensive cooling repairs down the line oh yeah and a lot of stress!!

Ps For those out there (hopefully no one here) that doesnt bother with coolant then you are massively degrading the internals of your engine and will almost certainly cause premature failure of the water pump because glycol is a lubricant for the waterpump and also has anti corrosion propertys to protect the engine. Nuff said!

Lee, sounds like text from a manual to me mate.

read all posts and its clear that i warned against being in close proximity to hot water.....

the sniffer test i mentioned is regarding exhaust gasses being blown into the cooling system... nothing else, the sniffer test is ONLY used to detect exhaust gasses in the cooling system.

previouse posts had already determined that no oil/water mix had been discovered and the therm had been checked out.

if matey had the cash to put it into a garage or join the AA he would have done so and not bothered to post his probs.

its plain to see you know youir stuff but please realise not everyone is a retard like you meet on the side of the road.

read all posts, and then your reply mate, youve gone slightly over the top.

LOL......... Nah m8, straight from the horses mouth. From a manual it may well be but that manual is in my head. I do this daily so i know what im talking about (not saying you dont of course).

BTW you did say to 'remove a hose when the engine was hot'...
Safety first and all that..

Not meaning to blow my own trumpet but i am an AA patrol, 16 years in the trade and only last week did a cooling refresher update course. The AA way is the only way because it is the industry recognised standard way of testing cooling systems. So if you dont use correct equipment, you are guessing. A full system function test on a cooling system takes about 1 hour. We do it at the roadside, any faults WILL manifest themselves in less than that and so the appropiate action can be taken ie fix the car or tow it to a garage depending on severity of the fault.

Ps i'm not bitching i assure you -

LeeT5, whats your thoughts on these coolants that you dont need to add water to, specifcally the Motul one?

Honestly?? Never heard of it. As far as i know 'Motul' is a company name like 'Castrol or Shell'. As for not adding water??? are you sure its not already premixed?

Dont some racing people run 100% coolant.


There is enough decent oil in this engine isnt there?

No, because running neat coolant is the same as running neat water. It will not raise the boiling point.

hmmmm

lol not enuff money
sorry chap you have that wrong but it is an old car that is purley for a loan for afew weeks

i have ful aa with roadside homestart and relay so no problems there
but dont see the point in using it if i can fix it myself i could take a patrol off the road that could be attending to a young woman with a kid who is sranded with a puncture

all i did was ask some advice as i was running out of ideas

plenty of oil matey although it is due a change

[abdul]

i had a volvo 850 had the same problem changed head gaskets turned out to be the radiator was blocked

[t5tart]

seems the rad was blocked flushed it and it seems fine fingers crossed

Dont take this the wrong way but if you can fix it youself why are you asking so many questions? sounds like your not really sure m8 what your doing. The reason i said about the AA was because you would know what the fault is in less than an hour and dont worry about taking a patrol off the road cos there are always more patrols than jobs on the road. just trying to help!

isnt that what this forum is for to share knowledge??
I like to solve things myself I have one of those brains
I like to solve puzzles

however i never thought of a blocked rad

[t5tart]

Thanks for all the help guys

seems the problem is fixed

£4.99 bottle od slick 50 rad flush through the top hose run it for 10 mins
proper 50/50 mix of coolant and de-ionised water
and she is so far running sweet

seems the rad flush was the key .... at least is saved me a head strip

Guess you werent in a rush to get your car fixed then (waiting for ppl to reply to Qs) anyway, well done for finding the fault, i might add at this point that all AA patrols carry laser temperature probes, so your blocked rad would have been found in minutes. At least it's sorted now.

[t5tart]

ah but thats the easy way out
and you are right was in no real hurry

would rater keep my aa call outs for real emergencies

as i said b4 the car was going on loan to a mate and his short hops to work were not enough to overheat it
but on the test run we did it did overheat so got my head scratching

[t5tart]

Happy to report that after 4 years stood on a drive very much unloved and unstarted
she started first turn of the key
needed one tyre where some vandal had punctured it
and an alternator (thanks salvo)
and the rad flushig and reflling with coolant

so £80 and she is back running sewwt
a testament to volvo's i think that she is in such good shape after beeing stood so long
