I don't think this is a problem I just need some clarification...when I replaced my pressure hose on my ps pump I pulled the lower radiator hose so I could get to it..of course anti freeze went everywhere...got everything back together filled my resivour (which is prolly 1/3 of what spilled from the radiator and went for a test drive...within 5 mins I got temps up to about 220...parked and refilled my resivor and still overheating...what's going on?

Gee oh Dee

Bubble in the cooling system.

Try my dumb *** pinching lower rad hose between pressure and return ps hoses...got half way down the road and it exploded

Xj88

Fixed that but I'm still rapidly over heating..is it most likely do to low coolant?

highmiles

sounds like a air bubble... does your rig have a closed system?

Xj88

Yes.

Xj88

The fluid in my resivor is draining out each time I fill it.

highmiles

keep filling it

Xj88

Think that will solve the issue?

highmiles

if its low on water and not being burned up or dumped on the ground....sometimes they can be a real pain to fill with water and not get air in the system

Xj88

Yea I've heard that..I'll pour more coolant in after class..hoping it is the answer

Gee oh Dee

Switch to the open loop system. Its not hard, it makes things easier, and can be done for less than $50.

Xj88

How? Haha

Gee oh Dee

either find a radiator and overflow bottle from a newer XJ or get Moroso's splice in radiator cap and use your old overflow bottle.

Several write ups exist. I may post pics in my build if I ever get around to it.

I will put that on the list of things to do...For now..do you think filling the coolant is the answer for my issue? Its def. been a PITA today.
