Replaced thermostat and water pump on my 2000 ranger 3.0 flex. still gets real hot after driven for a couple miles??????? please tell me why.


It could be a number of things. Cooling system not being bled correctly, blown head gasket, clogged radiator, incorrectly installed thermostat, bad fan clutch, or maybe it is not really getting hot and your coolant temperature sensor is lying to you. In any case, it needs to be properly diagnosed and repaired unless you really want to buy an engine.

Engine is getting hot


Obviously, check the coolant level first.
I'm sure you've already done that, so next would be to replace the thermostat. If the thermostat is sticking in the closed position, the engine will overheat.
It could also be that the radiator is getting plugged, in which case you'd either need a new radiator or you'd need to have the radiator professionally cleaned.
If it's "none of the above", it could be a damaged head gasket. Generally, if the head gasket goes it causes the coolant to blow out the overflow. Once the head gasket has failed the engine just won't hold coolant. If that's the case the only real option is to remove the head, have it machined to make it perfectly flat again, (overheating causes heads to warp slightly and a new head gasket won't seal properly) and reassemble.
Good luck. Hope it's a cheap fix for you.

Hi i have a 94 misubishi exspress van 2.0litre motor i brought it with a blown head gasket i had a mechanis pull head off had it tested and ithe head was no good now replaced with brand new head mechanic...


Yes, it sounds like the water pump or radiator is bad. And the car overheated in the first place, which warped the head on it. It is an aluminum head and if it gets too hot for very long then it will give somewhere. And that is what you bought. Or when the head warped, the engine did to. Or it cracked, and the antifreeze leaked into the cylinder and you leaked antifreeze there and overheated now. But it should have had steam coming out of exaust. Or running bad, missing? Did yoy have the water pump replaced?

Or he could have put the gasket on backwards and it blocked off one or two holes that the antifreeze travels through to cool that head and the intake.

I hope this helps.

Heater blower resistor gets very hot


the resistor is indeed very hot! and you are right it's cool by the blower, that's why most resistors are in the blower case.
the fuse was blown because it's not the right amp rating or the blower may be going bad.
