overheated GQ keeps stalling even when temp is normal

Post by **hottiemonster** » Tue Dec 30, 2003 4:14 pm

i was driving today in the mud at a secret location.

i was giving the car a bit ( 4000-5000rpm) going backwards and forwards trying to get outta this bog hole. i went back too far and go stuck for good, i was so close.

anyway.....

I overheated the Ford Maverick SWB and it was about 3mm from the "H" line. stopped to let it cool down and it did.

but it keeps stalling, even when i go home doing 80km/h for about 15 mins. this is on petrol.

i dont know what is wrong.

will post a couple of pics to show how dirty it was

any ideas?

maybe let is cool down overnight. but i suppose its been 40 degress.

could be dissy, coil, plugs, leads...check the usual suspects first

Could be a million things wrong. Could have done a head gasket, the 'could' affect idling.

More likely just a coincedence with the overheating and some dirt stuck somewhere it shouldn't be. Carbies don't take too kindly to being filled with mud. Another possibility is that there isn't enough voltage due to alternator being filthy.

Best thing is let it cool down, give the engine a good blast with a high pressure hose everywhere (even in the alternator). Give it some time to dry and then see how it goes.

there isnt that much mud in the engine bay, just all over the car, and shit loads of wheel spin and revin.

radiator full of mud, the only way on GQ"s to clean them properly, is remove them on a GQ. Hosing them out only gets about 1/2 the total area.

Seeing how dirty the outside of the car is really won't help us diagnose your overheating/stalling problem........

Try opening the bonnet......

i will get a pic of engine bay, but its fairly clean

it was just slosh, hardly anywater

the mud on the car is f***ing thick. there is not much mud on top on the engine bay casue i cleaned it a little 2 days ago

i just picked up the car fron ARB today to get the diff lock seals fixed and decided to play in the mud.

i have tried lots of things robbie suggested. such as:

* try to suffercate the car, by covering the air intake, by taking the air cleaner off.
* charge is normal 13-14 volts
* at the moment it is running on petrol which is shell optimax with a container of spit fire in the fuel tank
* tried to see if the secondaries are stuck by flooring it for 1-2 seconds, nothing.
* all the oil is fine and full
* there is enough water in the car and radiator (coolant)
* temp is fine now on the gage, but i dont know if i leave it running for 10 mins, comming home it was normal.

any other ideas?

Well, your problem is the mud not the heat, I am pretty sure.

Engines need air, fuel, and a spark. You have to check that all three of these are coming in okay. Air sounds like it's alright. That leaves fuel and spark.

Immediately after a dunk in the mud, you figure spark is the thing most likely to have suffered. So where does spark come from? Coil -> lead -> distributor -> leads -> spark plugs.

So you've got to open up your distributor and make everything in there clean, then you've got to yank all your spark plug leads and make everything there clean, then you've got to clean up your coil... etc, etc.

Good luck.

if it was spark, it would most likely have a miss..

Yep if it were mine I'd be heading straight for the dizzy/leads, pull all the ends of your leads off the plugs and check for gunk, pull the dizzy cap off and check for the same. Spray the crap out of everything with WD40, this is Victoria dude you have to carry around at least 1 galgameth can of the crap even in summer.
I always spray it on all the vulnerable area's before any offroad trip and again prior to a river crossing or boghole.
If you have done a few muddy/boghole trips it's probly time the radiator comes out for a good clean, takes about 1hr for a GQ.
I find after about 5-6 muddy trips the radiator needs a clean as the next trip she will start to heat up on slow hillclimbs.
Also remember to grease everything VERY regularly, driveshafts, steering/suspension components otherwise things wear out very quickly down here. I try to do this after every muddy trip.

I'd junk that "showpony" chrome air cleaner if you want to play in mud, next best thing to a under car snorkel for getting water down the carby.

A guy in our club has a GQ petrol on gas with a Safari snorkel so it must be ok.

Well the GQ is here now at my place, no serious issues I believe.
Dizzy, leads, plugs are all fine but it wouldn't idle (just stalls) so we cranked the idle screw up a bit and it now seems ok. The main idle screw seems very loose and may have moved with a lot of offroad thumping (Vic Range).
The radiator looks fine to me so I'm not sure about the overheating bit.
