My 1990 DA...LS/Vtec, Only over heats after I get on it, if I drive slow and normal lol it doesnt over heat or atleast not as fast.Is it the Waterpump? i always have coolant in it, even after it over heats, and my fan does turn on.

 

bump please

 

is there a leak anywhere? waterpump area?

 

no

 

what water pump are you running? if you have a non-vtec waterpump then it doesnt pump as fast as a vtec one... so that could cause overheating when you "get on it"...

and inspect your radiator and see if there are any dents or anything of that nature as that could cause it as well

 

chcek ur theromstat also to make sure thats working peoplery it might not open up when u get on it
