Last time my car was running was in the summer, I noticed coolant was collecting on top of the engine right under the carb.

The following pic is not of my car but is labelled to give you a better idea.

 

most likely this is a problm with the O-rings between the manifold and engine.
Get as gasket and o-rings (two) for the intake and replce them. Not that much work, and a good time to refresh the coolant

 

Want me to have a look at it sometime?

It might have just been spilled there, did you soak it up and see if it came back?

 

but a simple search would have told you that.

 

i had the same problem about a month ago

then it just dissapered.

aparently its a good idea to just block off the coolent 'tunnels' into the carb.. (unless you live somewhere where it is frequently under 0 (or 32, bah)
and if u do that make sure you get a new gasket aswell.

 

Same here

 

its your o rings, odd part about mine are that it only leaks if the engine is cold, once it warms up they must expand or something, then its fine. whatever....

 

It's the coolant o-rings. Like they said, replace them and the intake gasket and you will be good to go.

I just called the local mazda dealership and they want $284 cdn each. Thought they would be a few bucks. You guys know anywhere else that sells them?

 

VB has the stuff, should be less than $10 for the gasket and orings

 

O'Reillys has them for 9.50 also. Should only take a couple days for the gasket and o rings

 

umm, don't you have to rebuild the motor to replace teh coolant o rings? or are you guys talking about something else.

 

if you pull off your intake manifold there is a gasket in between that and the engine. In the two coolant ports on the intake maifold (circle shaped) it indents a couple of milimeters, one o ring fits into each of these two holes place the o-rings in there throw your new gasket on and seal it back up. pretty simple and can be done easily and painless. You can also order the gasket and o-rings from www.racingbeat.com.

 

install a new intake manifold gasket and the two rubber o-rings...the job taked about 1/2 hour and will cost aroung $15.00 in parts from the mazda dealer

 

any one here closed off the colant passages thru the intake manifold?

these are what i need right?

 

I am experiencing the same problem on my 84 gsl-se. Losing quite a bit of coolant and refilling about 16 0z. everyday.

motor was rebuilt about 7,000 miles ago w/ new intake gasket and o rings. Why else would it puddle up on top of the engine by the intake manifold? are there any smaller coolant hoses that could leak? can't seem to find the leak and am not convinced it's the o rings on this fuel injected motor, any suggesstions?

anyone?

 

Is the intake manifold torqued to specs?

 

You copied the wrong link. If this is what you meant to post, then yes. http://www.racingbeat.com/resultset....rtNumber=16735

 

well you have small cooling hoses under re-egi that could be leaking, they are hard to get to, so one of them might have a loose clamp or have a cracked hose
