Overheating while towing? Low weight.

[JHarris1385]

Well *****, was not looking forward to having something wrong with it!

I am over 100K now and its probably time for a new water pump.
How difficult is that repair?

The cause of the wetness above is power steering?

- I did overheat enough to blow out the reservoir off roading about a month ago.


+ Today the temps outside are about 20 degrees lower and today I was running much cooler.


No brakes on trailer and the bearings MAY need attention.

See Barts timing belt "how to"...

Pretty much all the same shtuff has to come off to do the water pump, & since you're already in that deep...

Giv'er a new timing belt & tensioner too.

Thanks for all of the advice.

I wasn't able to locate where the thermostat is at exactly. I must have passed it up in the repair manual.

By any chance can someone point me towards it? Or a pic of the area where its located.

- Today - about 50 degrees outside, highway speeds, ran about 200 degrees.

It's part #1 under the coolant return pipe #215 that comes from the bottom of the rad that sits on block 'B'. However, the entire intake sits right on top of that location. So, the whole intake has to come off just to replace the thermostat. It's a big job.

Maybe the system developed an air pocket when you were trying to refill the coolant after this happened, and the system just didn't get topped off adequately?

Have you tried getting the system to operating temps high enough to open the thermostat, then taking the radiator cap off to see how high the fluid level is in the radiator as the coolant is flowing?

Since you most likely refilled it, the reservoir may be showing the right level, but if the coolant actually in the system hasn't been full enough since the off-roading incident to get high enough to overflow into the reservoir, it's possible the reservoir level has simply never changed since you topped it off even though the system is actually running low.

If you've ever visualized the actual height of the locations of both the thermostat and coolant temp sensor(s) in a cooling system compared to the height of the coolant flowing in a radiator when the system is full, you know that they are basically the same, and if the fluid level is low, gravity could be preventing the coolant in the system from getting high enough to cool the sensors reading the coolant temp, resulting in high readings.

If you're lucky that is. Sometimes it's the simplest stuff that get's overlooked, sometimes not.

After the intake manifold comes off, this is the view...
