What do I do about my car running hot?
I have a 94 geo prizm that keeps
running hot. The water pump is good.
I just gutted and put a brand new
thermostat in it. I was told my heads
could be going out to put some block
seal in the radiator so I followed the
instructions on the bottle and its still
running hot. When I first start the car
up it runs perfect for about 5 to 10
miles then starts running real hot so
what do I do?
how old is the radiator,it could be blocked.
I really have no clue! It looks newish maybe a couple years or so but idk
If its blocked how do I unblock it?
Never ever ever put any type of sealer in your cooling system, it causes more problems than it cures, plugs radiators, heater cores and smaller water passages in your engine. Have the engine block checked, that will tell you if you have a head problem or not. Just the way you stated you problem I would say that you have a radiator problem, slow coolant flow internally or plugged cooling fins externally.
Get it flushed or just replace it. They cheap and a new one will out last your 20 year old Geo.
How cheap is a new radiator?
$100.00 or less. Look online and check out EBay.
