Why does my mazda drifter 2.5sleTDI the top radiator hose gets very hot and the bottom hose remains cold after a long trip.


The top radiator hose is were the hot coolant goes into the rad and the bottom provides cool to return.
If you hold your top hose while warmed up and running you can see if thermostat is open you can feel the coolant moving through. careful its hot mike

What would be leaking under my radiator on the drivers side?


It sounds like your thermostat is stuck closed. Your thermostat also acts as a heater valve to let hot coolant go to your heater core to blow hot air if your thermstat is stuck close it prevents your coolant to run through your radiator to cool down and to blow hot air from your heater core. A way to check to see if your thermostat is working while its at operating temp feel the bottom and top radiator hose if your lower hose is cold and top is hot your thermo is stuck closed but be careful hoses might be very hot

How to replace a radiator on a 2003 mitsubitshi lancer es


make sure the engine is cold , drain the coolant from the rad ,there will be a drain tap/bolt on the bottom of the rad ,be sure to us a container to collect the fluid as should'nt be left to run down a drain etc as is very toxic,disconnect the top and bottom hoses, there are usually two bolts either side of rad loosen these, rad may lift out if not remove the bolts and lift the rad away and out of vehicle , if the cooling fan is attached to the rad remove , will be obvious what bolts need undoing, replace this fan unit on new rad ,then refit new rad , reverse of removal , dont for get to check the drain plug is closed on the new rad , refill cooling system by adding coolant to the expansion tank, run the engine and bleed the air from system ,there will be bleed screws at various points around cooling hoses etc , allow engine to cool 1 hour min ,check coolant level top up and repeat bleeding process as neseccary good luck very straight forward job , keep me posted

98 grand cherokee little heat.heater hoses hot top rad warm bottom is cold collant barely luke warm


While it doesn't seem likely, if you've changed, or had the thermostat changed.... I'd say you got a faulty thermostat. I am curious as to what your temperature gauge says the temperature of the engine and coolant is.. If your gauge is showing hot, I can think of two more possibilities... the water pump isn't pumping right... and, if the water pump isn't working right, the problem can be a cracked head or block, which can cause an airlock in the coolant system. Check the coolant or radiator cap.

Why is my car running hot?


Check the coolant level when radiator cools down, check if the rad fan is working, check if both the rad hoses are hot when vehicle is running IF the bottom hose is not as hot as the top one then change the thermostat. If both rad hoses are hot then flush the cooling system making sure you evacuate all air when filling with coolant.

2000 Linc Cont overheating. I replaced water pump, thermostat, belt & tensioner, blew through top hose out bottom (rad not clogged). Top hoses hot, bottom hose cold.


Do you have any coolant flow thru radiator with cap off?

Is thermostat in correctly?

Do a Combustion Leak Test at radiator or cap,
on gases from coolant. You may have a Head

Have a Peugeot 406 1.8 petrol LX on a 52 plate. Smell of coolant in the cab, no visible leak, top radiator hose hot, both hoses to heater matrix hot, bottom radiator hose cold. Air con works fine.


it could be a slight leak from the heater matrix (check for damp in the passanger foot well) its self or the thermostat may be sticking this may cause the bottom hose to stay cold. you could try removing the thermostat and running it without it and then putting a rad weld in the coolant system to seal the matrix.


let me know if this helps


cheers big mike

Coolant leaks


That's probably coming out of your coolant return bottle. With rad cap off & engine cool, look at your level in the rad, if necessary top it up to an inch or so from top. Start engine, turn heater(not defrost) on and let it run until up to normal operating temperature. Keep an eye on temperature gauge & rad level. When it's at normal, watch for good flow going through rad when thermostat opens. after flow slows down,(thermostat closes) top it up if needed. If you watch 2 or 3 times for flow, and gauge doesn't go over normal, then put cap back on, then fill bottle only to mark for warm or hot engine, with coolant. If gauge goes up over normal from there, replace thermostat, and I'd get a new rad cap too. If that has electric cooling fan, make sure it comes on shortly after you see thermostat open & coolant flowing through rad.

Coolant system


If your coolant level is dropping, I would suggest that you take a good look at the water pump. That is a very common coolant leakage probelm area on your vehicle. I change 2-3 a week.
Hope this helps.
