Van overheats intermittently and rises quite high (based on the dashboard gauge). New radiator, thermostat and temperature sensor but continues to happen. Fan relay was checked and seemed fine, fans come on late and were not consistently running both stages. Temperature seems to be more steady with air conditioning on.

had the thermostat changed out.......water pump changed out...... the rad flushed then later changed right out replaced new...... the aternator changed out...... a few hoses changed out....what else can i try? please help.....is there any change if i get the auxerilly hoses cleaned out oh and we got a new ah i forget but going to have to replace everything new soon to figure this out

Had oil changed and fluids topped up 1 month ago. This week red thermometer light came on suddenly and car quit on highway. Had towed. Gaskets replaced after same problem 18 months ago--cost 1600. This mechanic not sure if first mechanics (out of province) actually replaced head gasket as it was "severly warped". Bolts cracked. Mechanic said this is an ongoing problem with this engine. Bought from Burlington Auto Park in 2004 but they never mentioned this.

We replaced the thermostat thinking it was sticking shut and opening finally off and on to where the temp was overheating to where the warning temp light came on at 260 then it will suddenly start kicking heat out bringing the engine temp back down.No leaks appear to be happening of coolant and just a frustrating problem.

first off i think dex-cool is overrated. it does nothing but leave sludge(gel) in your radiator.secondly the engine is so backwards noone wants to work on them.thirdly ive tried different mechanics and they cant seem to find the problem. im also having electrical problems, the brake lights keep going out. ive been pulled over constantly by police.
