Overheating of 98 Suburban 6.5 Diesel K2500

After replacement of waterpump and thermostats my vehicle started heating up to 117 degrees before it would drop down to mid 80s then wouldnt go over 92. Found last week that they fitted the thermostats in the wrong way around, I turned them around and also replaced coolant bottle cap but still have the same problem. Was chatting with Benimur and he suggested new thermostats or remove them totally, he mentioned you were also in Aust. so just thought I would ask your opinion if you dont mind

Hey mate.

As we don't have major issues with engines running too cold in Au, you can do away with the thermostat. I don't remove them totally, you should always use a restricter plate(a thermostat with the valve part removed will do it) otherwise the water can circulate too fast and you actually lessen the cooling systems effectiveness. It is probable that the thermostat is faulty by the way it is behaving.

When you say the wrong way round, which side was the spring facing, the engine, or the radiator.

K2500 Suburban with. 6.5 Diesel and the instrument fuse keeps blowing when I turn the key to the on position. When I disconnected the glow plug relay the fuse did not blow. Also while running with th


did u replace the relay just a curious question, sometimes they have rust and water in the inside of the relay but my guess would be that you have a bare wire rubbing somewhere, causing the fuse to blow, anything significant has happened before that issue?

You may want to flush your system and also check the clutch fan as well.

Only 2 parts remaining are the thermostat and waterpump. Always start with the thermostat when diagnosing an overheating problem. If the car is overheating constantly under all conditions and coolant is backing up into the reservoir, it's very likely to be the thermostat. If it only overheats at low speed or idling, it's more likely the waterpump.

Overheating


Your overheating problems can have several possible causes.
1) Airlock in heating system - solution - bleed air from cooling system.
2) Radiator blocked - solution - drain and flush radiator
3) Failed waterpump - solution - fit new waterpump
4) Engine thermostat stuck in closed position - solution - fit new thermostat
5) Electric cooling fan (if fitted) failing to operate - solution - check fan, fan operating switch, all wiring and connectors
6) Not enough coolant in system - solution - check and top up to required level. Also check all hoses for sign of leakage.
7) Faulty temperature gauge giving incorrect reading.

My 1998 K2500 suburban overheats when you first start the vehicle and drive it will heat up to between 96 and 117 celcius after which it will drop to mid 80's and wont rise over 92 which is as it should be


sounds almost normal..albeit a lazy thermostat likely....when did you last flush and fill the radiator and replace the thermostat?...fan clutch and associated belts and hoses should be inspected at this time also
