My motor kept heating upto the n,o in the normal word on the temp gauge when i went up to queensland. I took it to a radiator repair shop and they said a lot of sludge came out. the car is still not running like it used to and there doesn't seem to be any pressure in the top hose apparently this is normal they say. what do you think? i have been running it on gas for the past year but have switch it to petrol to run injector cleaner through it today. how can you tell if the pump has gone?

Hi, this is a few months old but here we go
when radiator coolant goes past its use by date, it turns into a brown sludge. this sludge can block your heater core and most important, it may block up your gas converter, this is best tested by an lpg installer. the other common cause for the over heating and performance reduction is caused by the automatic transmission, again the only way to test is by a specialist.
as to just testing the water pump, first remove the drive belt, then move the hub up and down - if there is any movement at all, or any visable water leaks it must be replaced. while the belt is off check all the idler pulleys for movement or noisy operation. the other common problem is the thermostat, it must be tested to make sure that it is operating at the correct temp. if it is not there the water in the engine cavitates(bubbles) causing the engine not to cool properly as well as preventing the engine to operate properly. if you have the gas man check your cooling system he will modify the thermostate so as to allow optimum water flow for the gas converter. always use your petrol at least once a week for 2 reasons 1 it keeps your injecters 2 unleaded fuel is only good for a few months ( it starts to smell bad and then sets like a jelly and blocks every thing)
i hope this helps
cheers and happy motoring
i hope this help

Take your bottom hose off and let the water run out, once this has stoped start the car and see if water flows out as the pump will force the water from the engine out, but this doesn't mean its ok, take the belts off and spin the pump pulley, does it make any nose, does it feel rough to turn?
As for the sludge have you replaced the water and let it out again to see whether the water is sludgy still?
have you been losing water over time, does your fan work?
Buy a radiator additive to flush the system out if no leaks have been detected, this will clean the system.
Once you've put it all back together and filled with coolent (critical) check to see whether the water bubbles with the cap off the radiator.

Temperature gauge cold then back to normal

You have to make sure the thermostat is working properly and is the correct one. Idle the vehicle for about 20 minutes and then feel the upper radiator hose. It should be hot to the touch. Drive the vehicle and when the temp gauge falls to 'cold' stop and feel it again. If it is much cooler to the touch than before the thermostat is defective or wrong.

Heat blows out air but does not get warm, any ideas?

If it is faulty, yes.
Does the temp gauge show the engine is warming up to normal temp ?
Is the radiator full of coolant ?
Are the heater hoses getting hot ?
It could also be a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

1996_gmc_sierra Heat gauge started going from 260 degrees back to normal. I replaced heat sensor then thermostat. This summer had complete radiator and cap put in. The gauge says its running at 230 an

My Mountaineer had a similar problem. When driving it, the temp needle would slowly go up and up for like 3 minutes then it would come down within about 30 seconds. Then it would slowly rise again. just kept doing this over and over but it never went too high. My gauge didn't have numbers on it but it would go up about half way (not near the too hot level though) then fall back down to about a quarter of the way on the gauge. Found out that the fan clutch was bad on my radiator fan. It was not engaging and disengaging at the right times. New fan clutch solved the problem and probably saved the engine from overheating eventually if it had gotten even worse.

Weird problem just started. Noticed the other day when I turned off the car, the fan continued to run for about another minute. Then, this morning, I was sitting in the car with it running and...

the first thing to try is turning the heater upto full heat(a/c off)if the temp guage goes down THEN CHANGE THE THERMOSTAT...(hot oil,if too hot, is thinner than the normal sae rating so the oil pressure will be lower.otherwise no real problem.
