I came across your post. I wanted to know, is your fan connected direct and do you have a thermostat installed or have you taken it out? If you have installed a thermostat and made you fan connected to run automatically, the next issue is, have you checked to make sure your radiator fan is running properly and at the speed it should? Do you have 1 fan or 2 fans? If so, is the speed on both of them the same?
Fan is direct, hvnt checked the thermostat, fan speed is awesome, 1 fan for radiator and other is for AC, radiator 2 core/naali
A lot of the time, when your car is cold and you turn your AC on for the first time in the morning, the fans should be turning at half the speed, and when the AC high side pressure becomes higher, it will trip the relays to make the fans run at full speed until the evaporator coil temperature is very cold, then it will trip the relays to turn the fans off. Check all your fan relays and condenser fan relays, if you have those. Also check your fuses and medium current fuses for any corrosion at the terminals. ( will check)
You should also check your fan relays for resistance. Sometimes what happens is, when some of the relays have resistance, then the full power is not being sent to the fans. Therefore the fan turns SLOWER than it should ALL THE TIME. That could be another problem you are facing.
The other issue with your A/C is, do you see any bubbles in your sight glass on the receiver drier? Look on your receiver drier and there should be a round circular glass. Turn your AC on and the fan speed to full and look at the sight glass. If there are bubbles coming, then your refrigerant gas is low. If there are no bubbles, then you should be alright. (GAS is filled a month back, I ve checked my self no bubbles)
Another item I would double check is the water pump. If you have not changed your water pump in more than 5-6 years OR have only ever ran plain water, change your water pump FOR SURE. Sometimes the water pump impeller has corroded so much that it might not be able to cool your engine when a load is a placed on the engine. I have seen this happen before. (Haven’t checked I will get it checked to mechanic.)
Does your coolant stay full all the time or do you have to keep adding coolant to the radiator? Is your heater core blocked or is working and blowing hot air? Did you check to see if there is any air trapped in the system? (Yes I use to keep adding coolant to the radiator not regularly once in two week, heater is not working, plz tel how do I checked air trapped in system)
The last thing I would have checked is your Engine timing and CO test. Sometimes if your timing is off, it might cause the engine to overheat. It is not very often the case that it would overheat a lot, but it might be causing your issue. If your exhaust temperature is very hot, then I would say that a timing or EGR Valve issue is there (if you have an EGR). (unable to understand)
