Help!
hello, my 79 CJ5 is having a little bit of issues.. after being driven for a while the jeep stays cool... however when i go and park it.. the water temp goes up to a little over 190 and then it takes a little while to start... also.. i have noticed some residue in my radiator.. looks almost as if a little bit of oil has mixed with the coolant. any help would greatly be appreciated.
