compression test

[I-AM-THOR]

Manual says

Standard 242 psi

Limit 148 psi

Difference 28 psi

Mine was hitting between 185-190. Is this bad?

[Stu]

Its within spec

[I-AM-THOR]

Its within spec

 

Thanks. That's one good thing at least. Just gotta find why its over heating and leaking oil.

[Stu]

where is it leaking oil from and what do you call overheating?

how hot is it getting?

Im not too sure, it gets really hot.

[Stu]

whats really hot??

what does the temp gauge say does the fan kick in and out?

some people think 90°c is hot but its not!

It gets so hot the red light kicks in. Maybe something like 180

[Stu]

180 degrees????

all suzukis are set at 140 and the engine will shut down if it gets that hot as its a built in safety feature!!

[I-AM-THOR]

Think Its °f if that makes a difference?

Iv had it higher than 180, its never cut out but if hit high enough it spits out coolant. Its only ever happened twice.

[Joeman]

thats only 82c so not hot at all..

wheres the coolant coming out?

[Stu]

180°f is 82°c which is normal

140°c is 284°f

have you over filled the coolant and have you put the right amount of antifreeze is as this reduces the boiling point

is the rad getting hot? does the fan cut in?

you need to verify all this before replacing a head gasket or engine!!

and overfilled expansion bottle will cause it to piss coolant all over the floor

are you getting any oil in the water or water in the oil? is the exhaust steaming constantly even after a long ride?

Maybe I'm wrong with the °f then, I will check in the morning as it has no spark plugs in atm. When I switched it on it was on °f. I think when it leaked it was on 240/250. Red light would come on and the temp gauge would flash.

It would leak out of the front near the rad.

There is a lot of heat from the rad, not sure on the fan, I will fire it up in the morning.it got so hot upfront that it melted my rec/reg wires.

Coolant isn't over filled, what was weird was bike had plenty of coolant one min and the next main it was gone. Topped it up and it went down quickish. Left the bike for a week and when I went to fill it the coolant was back.

[Joeman]

Drain the coolant completely and refil with the correct amount. That rules out any air pockets.

Was there any steam from the exhaust pipe?

Any bubbles in the expansion tank?

[Stu]

whats your location? stick it in your profile there maybe someone close by willing to help

have you checked pressure of the hoses when hot it could be a faulty rad cap letting too much coolant out

I will do that and check everything that been said and report back

[Mr Fro]

When does it do this by the way? When it's standing (prob fan/switch/fuse) or when you're riding (prob air lock/thermostat)?

Standing. Its fine when I'm riding cos the air cools it down but once its stood or not moving as fast temps go high.

Maybe a little back story is needed, I had an oil leak on the bike and rode it slowly for a mile or two. Got it checked over and the bike shop said everything was ok. About a week later bike starts overheating and a possible loss of power, some said maybe it was me cos it was a new to me bike.

Took the bike back and they didn't really know what was wrong, he said its possible iv blown my gasket but he didn't know 100% and would cost a lot to find out why. Told me to manage the heat or change the engine. So I managed the heat by only taking her on the motorway. Overheated twice cos I was getting some bits and got stuck in traffic.

[Mr Fro]

Then it sounds like the fan is not kicking in so firstly check the fuse. If that's alright then try connecting 12v straight to the fan terminals - if it spins up then your switch is probably iffy.

Have you checked your coolant/oil yet? If you've got mayo in the expansion bottle or can see it through the oil sight glass then you may have HG failure. Otherwise, check the simple, cheap things first!

Not yet, off to asda in a min to get some.

[I-AM-THOR]

Tested the bike and the fan didn't kick in. The coolant bottle was bubbling like a kettle. Checked exhaust and it wasn't smoking.

About to check fuses and finish the flush.

[Stu]

And the temperature at the time? Also degrees c or f

Sounds like a duff fan or stat

[I-AM-THOR]

240-250 °f, didn't fill the tank enough with coolant only got a 1 litre.

Weird when I checked the fuses they were in the wrong order, fan went mental but ignition wouldn't work unless I used a 15 instead of a 10. Engine was already warm and even with a working fan temps were still going up.

well the temp would go up if you dont have all the coolant in there!

Change your display to Celsius. Fahrenheit is sooo last century!

[Mr Fro]

Kelvin is the future!

Erm... One of those fuses isn't blown is it? Can't think why it wouldn't work with them switched round unless one of them was u/s.

[Joeman]

So lets get this straight... the fan was not working, so you swapped the Ignition fuse for the fan fuse, then the Ignition stopped working and the fan started working...

have i got that right??
