running hot

[jawa]

it just started doing this it used to be just under the half mark,
any ideas whats wrong>

Coolant low? Thermostat bad?

[jawa]

coolant is good

thermostat was replaced 2 months ago

[worknprog.99]

well you most likely didnt bleed or "burp" the cooling system after you changed the thermastat it sounds like.

[jawa]

oh it was running at normal temp after i did the thermo. and i bled the piss out of it last week for 20 mins

[lord2heart]

you can try putting more water and less coolent and/or buy some watter wetter from advanced

[jawa]

ita pretty much all water

[lord2heart]

since you live in a hot tropical place it could be just normal but you could just buy a bigger rad

edit when does it get hot? in traffic? or just cruzin?

[jawa]

ok ive had the car here for 3 months and this past week is when it started doing this


where can i get a bigger rad

it gets hot cruzn and in traffic
i can be goin 75 and that pig is dam near 3/4

My car does this too, also been wondering about it.

I completely flushed and changed the coolant and T-stat about a month ago. When I sit on a hill or stopped in traffic it slowly goes up, but when I start driving it goes back to 1/2. Also, you can smell the cars oil when its hot, but it isn't leaking or anything.. Bad seal on the cap letting fumes out possibly for that I'm guessing.

[jawa]

mine dont return to half at all unless its turned off

[lord2heart]

when was last time cooling system been serived? i'm pretty sure its the coolent

edit. prettry sure you can buy the rad anywhere, internet, local car parts or whatever. just make sure you measure if you decide to buy a bigger rad.

[jawa]

coolant is pretty much just water

do i gotta run the dex garbage?

im thinkn of upgrading the rad and fans

[widbyj]

These cars run too hot for plain water. Flush it well and fill with a good mix.

Since I've had my car it has always run at 3/4 sitting still...this is of course dependent on the weather. In summer months she gets up there in winter it never move past half temp. I'm by no means a car person but are the fans turning on when they are suppose to? If the thermostat is good, and the coolant is good, and there are no leaks so the level is good...what else can it be? Could there be a pump problem I wonder. Maybe one of these engine gurus will be kind enough to help you out.

[jawa]

yea my fans are comming on im leaning tward a partially cloged rad .

[worknprog.99]

ita pretty much all water

then theres your problem :coolio:

[lord2heart]

partially cloged rad .

that could be it, maybe

Since it's all water you should have no qualms about pullin off the radiator hoses and using a hose to blast some high pressure water through the radiator... get a decent nozzle that'll seal pretty well, I use this:

makes a good seal so you can really blast it out.

Then you need a good 50/50 (or preferrably 60coolant/40water) mix.

Running straight water is a terrible idea... You could be boiling the whole system, and if you're unlucky you've already destroyed something!!!

water boils at 220*. The radiator cap raises the boiling point by 3xRatePSI (aka 45*). Thus your coolant WILL boil at 265*, and with your car running at 3/4 that's getting dangerously close.

The proper mix of coolant not only freezes at a lower temp than water, but also boils at a higher temp, protecting your engine from boiling and destroying gaskets!!!!!!

What happens if you overflow your radiator reservoir a little bit?

[lord2heart]

What happens if you overflow your radiator reservoir a little bit?

nothing, mine is overfilled a bit and still runs just fine

[jawa]

ok i flushed every thing moter and rad and put the green shit in it today

yesterday it was into the red and after i did the flush,
its at the same spot runs above the 3/4 mark.

Hmmmmmm, well now we've got problems.. however that wasn't in vain, at least we now know there is indeed a problem.

One easy thing to check.. are the inlets on the bumper clogged? Some cars are finicky, on my Aurora when I moved the license plate so it covered a little bit of the opening it ran at like 230!! Moved the plate at it cooled right down. Check that first, maybe you hit a plastic bag or something silly.

How many miles are on the water pump?? Once in a great while the impeller completely gives out.. corrodes away, etc. If it's quite old that's something to change, just in case (can't really know until it's off if it's bad, sadly)

Also, no air getting into the system? I know you bled it a lot, but go bleed it a couple days later.. is it still OK or are there more bubbles? Does it lose coolant? Look under the oil cap, is it muddy in there by any chance?

Get a cooling system pressurizer tool (fits onto the overflow tank and you can pump it up to 15psi) and pressurize your cooling system. Does it hold? If so, good, you know the headgaskets, LIMG, and all other seals are OK. If it doesn't hold , time to find out what's leaking and where!

There's
